The hydroponic substrate that outperforms its predecessors

PERFECT AIR / WATER RATIO

The Rocket Foam structure provides a near-perfect air/water ratio at all times, encouraging the development of a mass of finely branched roots – enabling better uptake of water and essential nutrients. The result is stronger, healthier plants and improved yields.

37% AIR BY VOLUME

Oxygen is as vital to healthy root development as water and nutrients. The open cell structure of Rocket Foam ensures good oxygen content throughout the entire depth of the slab or pot of flakes – even when Rocket Foam is saturated. Before Rocket Foam it was effortless to add water to a substrate – but far more challenging to add oxygen!

EASY WATER MANAGEMENT

Rocket Foam is impossible to over-wet/saturate at a maximum of 60% saturation. Even when the slab or flakes have saturated the structure of Rocket Foam ensures there is sufficient air for healthy root growth. Should Rocket Foam dry out for any reason, re-wetting is simple and trouble-free.

START WITH A CLEAN SUBSTRATE

Minimize your risk. Rocket Foam is sterile. This gives your young plant the best start to life. Rocket Foam has a starting pH of between 5.5 – 7.0 so there is no need to adjust your pH – just add your nutrient solution.

EASY TO USE IN HYDROPONICS

Lightweight and easy to handle – non-prickly. Rocket Foam is impossible to overwater. Rocket Foam provides the plant with easy access to water. In case of emergencies such as power failure, there is a good water buffer for your plants to maintain life. Rocket Foam has low cation exchange and flushes easily.

GREAT CAPILLARY ACTION

The great capillary action of Rocket Foam means that water is drawn up to the top of the slab. In uneven surface conditions where either ponding or dryness can occur, Rocket Foam is still able to provide a balanced air/water ratio in both the slab and flake form.
