100% CLEAN

SUBSTRATE

Growfoam

Growfoam is a patent pending tailor made biodegradable plant substrate for seedling germination and plant cultivation. Compaired to existing substrates Growfoam offers the following benefits for your Horticulture customers:

Clean & inert Growfoam material enables a completely clean and hygienic cultivation process meeting increasing hygiene standards especially in high intensity Vertical Farm or other Controlled Environment Agriculture Systems. Growfoam is NPK-free giving you a complete freedom-of-choice in your nutrient composition.

Biodegradable under natural & composting conditions (EN 13432) supporting your sustainability proposition. Growfoam will decompose in water and carbon dioxide without effecting plant growth (validated by plant toxicity studies at the WUR Wagingen Univerisity & OWS Research Facility).

Optimal potential for automation due to its sturdy structure. No risk of substrate particles ending up in your sensitive automation systems or water filtration units.

Growfoam is Peat Free & offers an ideal solution for upcoming peat bans in various countries Worldwide. Peat Free Growfoam delivers a direct differentiation possibility for you and your (retail) customers.

Growfoam plugs can be stored for maximum 3 months without having an impact to its performance giving you more flexibility in your planning and less wastage.

Discover the swift & homogeneous resaturation of Growfoam media. Even completely dry Growfoam substrates can be resaturated in a matter of seconds.

Growfoam growing media can be designed to minimize algae growth on the top of Growfoam substrate plugs. Each Growfoam plug has a defined water uptake height thanks to its well-defined capillary water uptake through its foam pores. This unique feature enables growers to define moisture levels, and therefore algae growth, at the top side of the plug during each cultivation phase.

Growfoam can be tuned in shape, composition, foam morphology (structure) and cell size enabling a defined water- and air capacity fitting your specific crop needs.

“Aqua Grow Plants Almere started using Growfoam Plugs in their Hydroponic Lettuce system in May 2020.

'Our interest in Growfoam was initially triggered by the plug/material being dimensionally stable which is a big benefit in our production system compared to the currently used peat plugs. Next to that the clean start we get with the Growfoam plugs helps us to stay clean during the whole production process (algae -pythium- phytophthora) resulting in less losses and therefore better income!!."
