GHE

GHE has tested a very large number of substrates to offer you the most efficient, best adapted to our systems, and the most environmentally friendly.
Separating the world from above ... from the world below
The substrate intervenes in the interface connecting the top of the plant to its root. The magic of hydroponic culture takes place in the world below, in the root domain, hence the importance of the choice of substrate.
Since the beginning of the hydrophony GHE has tested a multitude of gravel substrates of different kinds, coco fiber, mineral fibers such as fiberglass or rock wool, sand, sawdust, Perlite, vermiculite, plastic foam and a quantity of other products. After 20 years of experience, we have eliminated as many as possible for reasons as different as their efficiency, quality, and / or ecological impact.
