  1. EzGro Tri-Helix Solar WindmillBelieve it or not, there is some inefficiency in the renewable energy industry. For instance, what happens on a windmill farm when there is no wind? What if there are several dreary days and the only energy system a place has are solar panels? A Midwestern company sought to change all of that, and spent years doing research to come up with the best possible solution. EzGro Garden is excited to form a partnership with a leader in the renewable energy industry.

    The technology incorporates BOTH solar and wind energy into a hybrid technology known as a Solar Windmill. This innovative product consists of solar panels mounted atop three rotating wind turbines. Together, the three turbines are known as the “Tri-Helix;” they resemble twisting DNA strands. This technology allows for the integration of solar and wind energy into a much more efficient sustainable energy system. The compact, low profile design means that the Solar Windmill has the most dense energy-generation capability of any renewable energy product on the market. The Tri-Helix wind turbines are also silent, which means they are completely safe for wildlife, and don’t disturb the neighbors!

    The system has been designed to last 20 years, so there’s no need to worry about needing to replace it any time soon. The product houses a solar charge controller as well as “Maximum Power Point Tracking electronics,” which both work to maximize the power generation capability of the solar panels and the wind turbines together.

    The hybrid between solar and wind energy is the missing link in clean energy; because wind-only and solar-only systems are only able to work when that resource is available. By combining both into one hybrid system, we are able to produce a more consistent renewable energy solution. So now, we will not only be able to harness the suns energy during the day, we will be able to harness wind energy at night, when solar power is not available.

    The Tri-Helix wind turbines are able to improve on the current limitations for harvesting wind power. Most wind turbines begin turning in wind speed of five miles per hour, and will not start generating power until wind speed reaches 15 miles per hour. The Tri-Helix works with just a fraction of this amount of wind. The Tri-Helix turbines start turning in winds of just two miles per hour and will generate power when wind speed reaches four miles per hour. This is a huge difference in the amount of wind energy available for harvest, making this the ideal choice for renewable energy based on the wind requirements alone.

    In many parts of the world, there is often not enough of one resource to justify the expense of either a wind-only or solar-only energy system. This system is perfect for any location because it can utilize either solar or wind energy, or both, depending on the environmental conditions of the day. The extremely low wind requirements make this even more appealing in areas that don’t often experience 15 mile per hour winds.

    The system has been tested and proven successful all over the world, in many different climates. It has been used in frigid Scandinavia, as well as tropical Caribbean Islands where salt spray is often an issue. It has also been proven successful in the hot, sandy desert of the Middle East. One of many notable examples of the technology’s success is in India, where it has helped businesses comply with mandatory reductions in carbon emissions.

    EzGro has come up with several different models of the Tri-Helix Solar Windmill, and each is able to generate a different amount of energy spicily for our hydroponic gardens. The difference in the models is based on the amount of wind turbines and solar panels it has. The TH1-2 has one Tri-Helix wind turbine and 2 solar panels. The TH1-2 will generate more than enough energy to power an EzGro Garden system of 100 towers or less. This would allow our Backyard Garden to grow 3,200 plants without using any electricity from the power grid! Imagine being able to grow that many plants with very minimal effort: no manual watering or fertilizing required! The TH2-6, which has two Tri-Helix turbines and 6 solar panels, will be used for gardens with between 500 and 1000 towers, which will be able to grow between 10,000 and 28,000 plants. We even have systems to handle our fully lighted greenhouses.

    This is truly a revolution in food production. Combining EzGro’s proven vertical hydroponic technology with the renewable energy system of the Tri-Helix Solar Windmill will empower growers all over the world to get off of the energy grid. We’ll be able to grow large quantities of food without having to rely on traditional energy methods. This will also give growers the freedom to build greenhouses and set up systems in places where electricity is unavailable.

  2. EzGro Deck Garden[Best_Wordpress_Gallery id="2" gal_title="Deck Garden"]

    The EzGro Deck Garden is a brand new system recently designed to be lighter duty than the Rooftop Garden making it a more affordable solution. It may also be placed atop any flat surface, such as a deck, a rooftop, or even soil!

    What You Will Need

    It is of utmost importance to begin with a smooth, level surface. If your surface is not level, take care to prepare it by adding sand and using a level. This is the most important and involved step when setting up your deck garden. The area you choose should also receive plenty of sunlight, at least four or five hours per day. Take some time to make your decision, and observe the space at several different times throughout the day. This will ensure you select the very best location for your garden. Just like our other gardens, you will need a nearby source of water. An electrical outlet is necessary if you do not choose the solar panel option. If placing the garden on a deck or rooftop, it is important to consider the weight. When full, the 50-gallon nutrient reservoir will weigh about 350 pounds, and each tower will weigh approximately 50 pounds wet.

    What You Can Grow

    These pots were designed for almost anything you could think of to grow. Many different types of herbs including, but certainly not limited to, basil, parsley, cilantro, rosemary, thyme and oregano can be successfully grown in this system. A variety of leafy greens such as lettuces, Swiss chard, kale and spinach thrive in these pots. Flowering plants such as tomatoes, cucumbers, eggplant, sweet and hot peppers, nasturtium and marigolds may be grown as well. The possibilities are endless!

    How it Works

    The EzGro Deck Garden is specifically designed for the gardener who wants to grow food on top of a flat surface such as a deck, a parking lot, or any area you can’t penetrate into the ground. The design of this system is unique and the footprint of the base system with 5 towers is 3’ wide by 7’ long. Our most popular system has 10 towers and is 3’ wide by 15’ long. The systems come with everything you’ll need, including grow-media and enough nutrients for about one year of continuous growing. You’ll just need to provide the seeds and water. The quad pots stack on top of each other to take advantage of vertical space; the tower systems can accommodate from 200 to 600 plants, depending on the plants and system you choose. The nutrient tank houses a submersible pump that delivers nutrient solution to each tower. The plumbing runs from the frame at ground level, up through the center of each tower. Once at the top, the nutrient rich water passes over the root system of each plant. Roots take up the nutrients they need, and the remainder of the solution returns back to the reservoir where it will be recirculated. The system is composed of towers, each on a pedestal that is supported by a sturdy wooden frame. The kits include everything necessary to get started: your choice of white or terracotta quad pots, a 50-gallon nutrient tank, the wooden frame, stained in a color of your choice or raw, to support the towers, all the plumbing parts needed, and durable pruners for harvest. There are several options and upgrades available so that the system can be customized for your site and your needs.

  3. EzGro Quad Pots

    [yith_wc_productslider id=585]

    The Ultimate Stackable Garden

    Stackable pots are the best way to maximize vertical growing space. One square foot of a traditional garden plot can support just one or two plants, but stacking pots on top of one other allows twenty or more plants to be grown in the same space! There are many different ways to set up a vertical garden, and many different pots to choose from. This article explains how the EzGro Quad Pot was engineered to optimize vertical growing space and production.

    Quad Pots are designed to stack on top of each other; the corner of one pot fits snugly into a groove in the center of the side of the pot beneath it. The sides of the pot are angled in such a way to allow for a secure fit. This is a dual-purpose feature that provides two important benefits for growing. First, the planting sites are staggered when pots are stacked this way, giving plants a full 16 inches of grow space. This means the greatest plant density can be achieved without crowding plants. Taller plants can be grown to their full size without crowding. This is one of several reasons why all different kinds of plants- from lettuces and leafy greens to tomatoes- can be grown in these stackable pots. Secondly, maximum airflow, which reduces the frequency of pests and fungal infections, is achieved by keeping plants separated in this manner. Plants actually grow healthier because of the staggered stacking design.

    Quad Pots were even engineered to protect plant’s gentle stems by reducing the occurrence of pressure points that cause stem breakage. The pot has a rounded lip along the entire top edge, which is designed to be gentle on your plant’s stems and leaves. The rounded edge gently supports a plant when it hangs over the lip. Most pots have a harsh rectangular corner at the top, and plants tend to break when they hang over these edges. A broken stem is a point of entry for harmful bacteria, so the rounded edge on the Quad Pot is another defense against disease.

    The Quad Pot was planned to create optimal growing conditions in all seasons, which is a unique feature that can only be attributed to this pot. In summer when the sun is high in the sky, the large lip and the angled sides of the pot work like the eve of a house and cast shadows over the sides of the pot so the plants root system stays cooler. When the sun is lower in the sky in winter, the sun’s rays reflect off the side of the pot and warms the plant root system. This very intentional design works with nature to produce the best possible outdoor growing conditions all year round. Plants are cooled by the shadow in summer and warmed by the reflection in winter.

    Another feature designed into the Quad Pot is its rounded corners. When looking at the pot from the top down, notice the corners have been replaced with circular “pockets”. This makes more room for each plant to grow. If the pot was square, the corners would not be big enough to support larger plants such as tomatoes or peppers. This design makes EzGro’s hydroponic garden systems the best stackable gardens that can grow fruiting crops. Engineers who designed the pot did research to determine the correct amount of growing media needed for optimal hydroponic root growth of all kinds of plants. The size of the pot was decided after this research was complete. Each quad pot holds half a cubic foot of growing media, which makes the pot large enough to not interfere with plant growth and not so large that you are wasting space. This is the ideal amount of media that plants need to grow healthy roots.

    The final component to creating the best possible design for a stackable garden pot is the environmental friendliness of the pot. This is a very durable, heavy pot for its size at just over 1/8” thick. It is designed to handle heavy loads, as it weighs 1.2 pounds when it is empty. Plants can grow through the bottom or split other flimsy pots, destroying the pot, but this will never happen with a durable Quad Pot. EzGro Garden’s Quad Pots are made from High-Density Polyethylene (HDPE) #2 plastic, which is a 100% recyclable plastic. One of the best features of this pot is that the plastic will last over 50 years, so they never need to be replaced. This is a one time purchase that will last for years to come. Quad Pots are very easy to clean and sterilize for re-use. They can be scrubbed, bleached, or pressure-washed, the pot’s smooth surface holds up very well to all kinds of cleaning methods.

    When choosing a stackable pot for your vertical hydroponic garden, look no further than the EzGro Quad Pot. The pot’s design has been proven over and over again, in growing systems all over the world.

  4. EzGro Riga Greenhouses

    [yith_wc_productslider id=564]

    Why buy a Riga Backyard Greenhouse?

    1. If you intend to grow your own food during the winter, then the Riga greenhouse is the most suitable product – it offers more insulation than other units.

    2. Its special shape is designed to offer optimal head room inside, but with enough slope on the outside so that heavy snow loads slide down and severe winds blow over the greenhouse.

    3. The Riga Greenhouse comes with significantly larger and more windows than other Greenhouses.

    4. It has a large Dutch Barn style door – with a key lock in the door handle

    5. Its shelves hang from the roof and do not sit on braces – more storage space.

    6. The unique design of the Riga greenhouse has the best ratio between aluminum framing and polycarbonate panels, which allows for maximum light transmittance and less “moving” shade. (The side glazing panels are wider (40”) than those of other greenhouses, as such the Riga greenhouse utilizes significantly less aluminum profile materials)

    What are other unique features of the Riga greenhouse?

    1. It comes standard with oversized rear-wall window, 1 or 2 large roof windows (depends on the size) and an oversized 30” wide Dutch barn style door.

    2. 8 mm or 16mm twin-wall polycarbonate glazing as side panels

    3. 10 mm or 16mm twin-wall polycarbonate glazing in the front and back walls.

    4. Roof windows come with Automatic Window Openers

    5. Heavy-duty rubber seals are used on all the windows and doors as well as at the bottom and top of each of the large side glazing panels.

    Warranty: Aluminum Profiles: 15 years and Polycarbonate glazing 10 years, both against manufacturer’s defects. The Warranty of the glazing panels is prorated after 5 years.

    General Description Materials:

    1. Frame: Smooth finished anodized aluminum frame/profiles

    2. Glazing: UV coated 8 mm Twin-Wall Polycarbonate Glazing on the sides, and 10 mm twin-wall polycarbonate glazing in the front and back walls

    3. Heavy duty rubber seals

    4. Silicon caulk to seal around windows

    5. Door handle with key lock

    Frequently Asked Questions

    Does the warranty cover damage due to severe wind or a hail storm?

    No it does not. However, the type of weather which would damage the Riga greenhouse would be such that it would also damage your main house and/or other structures in your garden. In which case this damage would be covered by your home-owners insurance policy.

    How long does it take to assemble the greenhouse?

    Installation requires two people minimum Not considering site preparation – the assembly should take between 6-10 hours, depending on how many shelves are bought and/or the foundation frame is added.

    Who should buy a Riga greenhouse -The Perfect Customer?

    • Usually a some what serious gardener: either likes to grow most of their plants and vegetables from seeds, and wants to start before the winter is over, or

    • The serious gardener, who wants to grow some of their own vegetables and flowers during the winter season.

    • Some one who has already had experience with a greenhouse – but they bought an entry-level unit – and they now are ready to buy a real-greenhouse (to upgrade).

    • An orchid grower/lover.

    • Some one very concerned about eating only organic foods – very health conscious.

    Why buy a greenhouse in the first place?

    • Generally: To grow your own plants, vegetables and flowers from seed

    • To protect plants, shrubs, small trees etc. against frost during the winter.

    • To show-off – to pretend to be a serious gardener.

    Cost Justification -Why do prices of greenhouses vary so much?

    • Look at it this way: why is there such a wide price range in cars – they all have an engine, 4-wheels and can get you from one place to another? The more expensive the car the more value/features etc. you generally get. This is also the case with greenhouses.

    • Because: for one thing the experts don’t call all covered garden structures greenhouses, as is currently the case in our country. But in Europe where the greenhouse concept was invented over 100 years ago, they consider any structure using less than 8 mm twin-wall polycarbonate not a proper greenhouse but a “season-extender”.

    What is a “Season Extender”?

    • It is a structure covering flowers and plants designed to prevent a late frost from damaging the flowers and plants. They are too expensive, relatively speaking, or sometimes impossible, to keep warm enough (above 50ºF) during day time frost.

    • These structures usually include all “greenhouses” which use 5 mm or less twin-wall polycarbonate glazing. Or use only single layers of heavy polyvinyl sheeting, or 3 mm or less single layered glass.

    • To keep these warm enough in the middle of the winter you need so much heat that often the plants near the heating unit are damaged from too much heat.

    • The cost of heating these units properly is too high; in the long run it is cheaper to buy a better-insulated greenhouse.

    What is a (proper) greenhouse?

    • Usually, a structure which uses at least 4 mm glass or better still at least 8 mm twin-wall polycarbonate glazing. These units are designed to be used in cold weather – including continuous day-time frost conditions

    • A unit designed to be kept comfortable (about 50-53ºF) during the middle of the winter with out costing an arm and a leg to do so.

    • Less insulation can mean significantly higher heating costs.

    Why use twin-wall polycarbonate instead of glass?

    • In the old days twin-wall polycarbonate glazing did not exist and therefore all older greenhouses have only glass or a corrugated plastic type walls.

    • Cheap glass was/is cheaper than good polycarbonate

    • Since the invention of the twin-wall polycarbonate glazing it has become the new material to use – even the professional growers are using it now.

    • Twin-wall polycarbonate glazing is much more efficient – like a double pane window it provides much better insulation.

    • At least 40% cheaper to heat – for a same size greenhouse with 4 mm single layered glass or less.

    • Twin-wall polycarbonate glazing defuses direct sunlight – glass does not. This is important to sensitive plants.

    • Provides much better UV protection

    • Easier to handle – not dangerous

    • Easier to assemble – safer and lighter

    • Safer for children and pets

    Why is ventilation so important?

    Because, in this country temperature can change drastically from cold nights to hot afternoons. To compensate for this, the Riga greenhouse comes standard with larger and more windows than similar greenhouses. For this reason it comes with an oversized window in the back wall. In addition, you can leave the top half of the front door open allowing a breeze to flow through.

    What kind of ventilation is provided?

    • Automatic Window Openers with each roof window

    • An oversized 30” x 42” or 30” x 49” rear-wall window

    • An oversized Dutch barn style front door -30” x 72” or 30” x 79” high.

    • Additional windows can be added.

    How does the Automatic Window Opener work – does it need electricity?

    • No electricity is needed.

    • It comes with a special cylinder (black) filled with unique paraffin oil, which expands, and contracts due to temperature changes. It pushes the window open when it gets hot inside and closes the window when it cools down.

    • Temperature range is adjustable

    How are the roof windows attached?

    • FYI: with most greenhouses they hang form simple hinges, which can break if the window is left open in heavy winds.

    • The Riga roof windows are attached with a ‘tongue and grove” hinge system, which spans the full length of the top profile of the roof window

    • The top profile sits “inside” a grove in the roof beam.

    • It is attached by sliding the assembled roof window down the grove in the roof beam from either end of the roof beam.

    Can I install an electric fan?

    Yes, you can – simply cut the required hole with a utility knife in the polycarbonate glazing either in the back or front walls

    Does the greenhouse require heating in the winter?

    Yes, it might depend on outside temperatures and the needs of your plants. Standard recommendation is to keep the temperature inside at about 50-53º F.

    Zoning Restrictions:

    • In many areas of the country there are restriction with respect to adding some kind of permanent structure in your back yard, set by either your local government or by your neighborhood association.

    • Most common restriction: everything over 100 sq. ft. needs a permit

    • Or anything requiring a slab.

    • However, we are finding that more and more places are willing to make exceptions for a nice greenhouse – associations understand and respect the environmental benefit of growing your own food and plants. Just ask them for permission.

    • This greenhouse does not require a slab

    • It is not a permanent structure.

    Wind resistance:

    • Although there is no official wind rating the Riga greenhouses were driven on a flat bed truck down the German highway at 80 miles per hour and suffered no damage.

    • Basically due to its unique roof slope strong winds are diverted over the roof.

    • Additional wind resistance is provided through the 4 lateral support bars, which span from the front to the back of the greenhouse.

    • Recommendation: like any greenhouse the Riga greenhouse must be fixed to its location. We offer a specially heavy duty foundation frame – which can also be used to raise the greenhouse up to 5”.

    Snow load/capacity:

    • Due to the aggressive angle of the roofline it is impossible to measure the Riga snow load capacity – snow and other debris simply slide down the roof.

    • As the roof has no “shoulder” there is no ridge, for any snow to build-up on.

    • However, the roof is more than strong enough to allow a 185 lbs person to stand on top of it – in the middle of the polycarbonate panels.

    How strong are the shelves?

    • Strong enough to put several flats with plants on them or take a nap

    • Hanging from chains is stronger than traditional braces.

    What type of flooring do we recommend?

    • Please do not put any greenhouse on a concrete slab. Standing water on concrete is dangerous, especially when it freezes over.

    • A greenhouse floor should be free draining.

    • Usually people will create some sort of path (i.e. flag stones) down the center of a greenhouse – to walk on. The rest of the ground might be covered with riverbed stones, pea gravel, or pine straw or a similar material.

    • Other drawbacks of a concrete slab: stays too cold in the winter and too hot in the summer (reflects heat back up – making things even worse inside).

    • We do recommend, removing all grass and weeds etc. from inside the greenhouse area before assembling the greenhouse. And to cover this area with a weed control mat.

    • You can put a greenhouse on a deck but be aware that this will allow cold air to blow in through the deck. We don’t recommend this.

    Foundation Frame / Mounting system

    • The Foundation Frame attaches to the bottom of the Riga greenhouse profiles and usually sits in the ground, but it can also be mounted on top of 6” x 6” treated lumber, a concrete or brick wall to provide 5” of additional headspace inside.

    • This frame is designed such that when “filled” with dirt all around the greenhouse cannot and will not blow away in anything less than a hurricane wind. (We do not guaranty this)

    Can I make the unit longer/bigger latter on?

    • Unfortunately you cannot. The reason for this is that the roof beam, Base Profiles and the Lateral Supports are the same length as the greenhouse originally bought -this ensures optimal strength of the unit.

    • Roof Beam and Base Profiles are one piece and cannot be extended

    If for some reason some part breaks – can I get a replacement part?

    Not a problem – we carry spare parts of all parts of the greenhouse.

    Are there other window and/or door options?:

    Yes, additional roof windows (with Automatic Openers) and it is possible to put an additional door in the back wall

    What other accessories do we offer?

    • A bag with 10 plastic hooks – these can be used to attach a string to, to guide tall growing plants to (i.e. Tomatoes and beans).

    • A set of 5 adjustable metal hooks: for hanging flower baskets and/or ceiling lights and fans.

    Does the Riga greenhouse require shade cloth?

    If you are planning to use the greenhouse to grow and house exotic plants in during day time temperatures in excess of 85-90º F than virtually any greenhouse will need some kind of shade cloth and or missing system in order to keep temperatures down.

    Available Options:

    Additional Roof Windows with Automatic Opener – recommended in case the Riga greenhouse is to be actively used in very hot climates (during the summer) ie temperatures in excess of 90º F.

  5. The benefits of AluminetALUMINET (an aluminized shade cloth) is more expensive than black shade cloth. What are the benefits of this shade cloth, and do the benefits justify the increase in price?

    ALUMINET reduces heat load in the greenhouse. Because of the highly reflective nature of Aluminet, radiation is reflected away from the net.
    With black shade cloth, the radiation is absorbed by the net resulting in hotter nets. The black net thus provides a heat source to the greenhouse at a time when the greenhouse should be cooled. If ventilation is adequate, temperatures in houses with black net can be maintained very near houses with ALUMINET, but the fans will be working more to achieve the result.

    In situations where the heat load is pushing the ventilation to its limits, actual temperature differences will occur, with the ALUMINET being cooler.

    ALUMINET works as a thermal blanket. All warm objects become cooler by giving off longwave, infrared (heat) radiation. At night, the warm earth surface cools as it gives off infrared radiation. On clear nights, this radiation is lost into space. On cloudy nights, some of this radiation is reflected back to the earth by the clouds, maintaining a warmer temperature than would occur on a clear night (under otherwise similar conditions). Within the greenhouse, this same process is going on. The plants and floor give off invisible heat radiation at night.

    ALUMINET, when installed as a thermal blanket/shade cloth, reflects this radiation back to the plants maintaining warmer leaf temperatures. This decreases condensation on the leaves as well as helps to maintain warmer air temperature within the canopy. Because the net is open weave, air does pass through the net. While this tempers the thermal benefits to some degree (compared to a solid screen), this has distinct advantages, particularly with naturally ventilated houses. First, the open weave of ALUMINET allows better movement of hot air to roof vents when used as shade during the day, and second, it allows moisture to pass through to the peak of the house, maintaining lower humidity near the plants.

    In this shade house, Aluminet provides frost protection while less reflective nets in the background fail. Aluminet is effective in reflecting longwave (heat) radiation back to the plants at night.

    ALUMINET provides for more diffused light in the plant canopy. With black shade cloth, the net will absorb rays of light coming from low angles. Because ALUMINET is reflective, it will allow much of this low angle, (diffused) light to pass through the net into the canopy. In permanent installations, this can allow for more light into the canopy during the low light periods in early morning or late afternoon. While the benefits of diffused light have been minimally documented, personal testimonies suggestion many benefits including:

    1. Higher yield, especially in tall canopy crops. With direct light, the upper leaves get excess light and the lower leaves are in shade. With diffused light, the light is spread more evenly throughout the canopy. In a greenhouse tomato study in Israel, a 6-7% increase in tomato yield (11,574 kg vs. 10,866 kg for one manufacturer and 9972 kg vs. 9094 kg for a second manufacturer) was seen for films with diffusive agents (comparisons include the same films with and without the diffusive additives).

    2. More diffused light will minimize shadows within the greenhouse, giving more constant light throughout the greenhouse.

    3. Diffuse light gives more light into the lower canopy, which may stimulate branching.

    Notice the blue and bronze coloring in the strands of Aluminet. The blue is reflected from the sky above while the bronze is reflected from the fabric beneath it. Because the strands are twisted, Aluminet will reflect diffused light from many directions.
