Gold Label Hydrocorn is an RHP-certified expanded clay pebble designed for hydroponic growing and substrate mixes. The irregular shape and porous structure keep water within reach of the roots while letting oxygen through, which supports root development.

The pebbles are pH-neutral and do not bind nutrients, so the grower stays in control of the nutrient solution. The pebbles are suitable for drip irrigation, ebb and flow systems, DWC and NFT, as a drainage layer in pots and as an additive mixed into soil or coco. Rinsed and sterilised, the pebbles last for several growing seasons.

We measure this pack out from a large sack, so you get exactly the amount you need: a small test batch or enough to fill a few pots without buying a whole 40 litre sack.
