Plants are mostly water and need ample oxygen for healthy growth. Roots supply water and oxygen to the plants. Since both water and air (oxygen) move in, through and out of soil, water retention, drainage, and aeration are important considerations of any potting mix. The use of GroRock significantly increases air spaces, improving oxygen diffusion to the roots. It also helps store and move water through the soil. GroRock keeps your growing medium loose, well drained and aerated If the soil mix has poor drainage or tightly packed, oxygen is cut off from the roots, reducing plant growth. Whenever a plant is watered, air is forced out. In a loose, porous planting mix, as water drains out, fresh air is drawn in and ready to be used by roots. GroRock enhance the porosity of the planting mix, helping plants get the balance of fresh air and water needed for vigorous growth. Nothing is more important to successful growing than soil properties. Its condition and health can determine the condition of your plants. GroRock helps soil breath making it less dense, less clumpy and more workable. Customize Your Planting Mix For increased drainage, use more GroRock and for increased water retention, use more coco coir when creating your GroRock planting mix. How to Reuse GroRock Planting mix GroRock aggregates maintain there physical integrity through time. For this reason, GroRock planting mixes can be reused multiple times. To reuse GroRock mixes, remove old plant material from the container; shake roots vigorously to free as much GroRock mix attached to roots as possible.  Replenish container with new GroRock planting mix. Transplant the new crop. As with any substrate used more than once, it is advisable to sterilize the mix before reusing it. Alternatively, the mix can be simply added to soil to improve texture and structure. More About GroRock
