HydroStones grow rocks, or expanded clay pellets, also referred to as leca clay, clay balls, are one of the most helpful and versatile growing media to any traditional and hydroponic grower.
There are many reasons that you may gravitate towards the use of extended clay pellets for horticulture growing.
Water drainage. The biggest appeal seems to be the way that it helps to drain excess water, though they also keep enough nourishment for constant delivery of it to the roots.
Sterile. While expanded clay pellets last for a long time, it won?t actually nourish the plant. They have no nutritional value and are primarily meant to use as vessels for the other food provided to your plant. For this reason, they help to keep insects and bacteria away from the plant during growth.
Easy for harvest and transplantation. Because hydroStones is a form of pellets, it does not stick. You will not face much nuisance when taking the plants/seedlings completely from the grow pots.
