Grodan Rockwool offers many advantages to the home grower. Full control of the plants' needs, high yields and easy processing in the grow system. Grodan Rockwool has a lasting optimal water / air ratio and is completely nutrient-free so that every cultivation can be supplied with the appropriate nutrients. We offer mats and Growcubes as rockwool media and a variety of cultivation blocks for reproduction. The cultivation cubes fit into the grow cubes; those will be placed either on the rockwool mats or will be planted into another substrate. Rockwool mats are available in the size of 1 m in length and in widths of 15 and 10 cm respectively. The Grodan Expert Mat is made for one season, i.e. for approx. 6 - 12 months. The Grodan Master Mat is somewhat firmer in its structure and usable for up to two years. We also offer the 10 cm wide Grodan WFMX mat on request.

RFX-1 rockwool/PU flakes mix, 80 L RFX-1 is a new and innovative substrate for growing plants in pots and basins. RFX-1 is a mixture of rockwool flakes (earthwool) and PU flakes. Contamination with diseases and fungi is prevented, as RFX-1 contains no recycled materials. The earthwool in the mixture only contains mineral-based binders (ECOSE) that are free from acetylate and formaldehyde. Organic life required for strong and sappy plant development is also added to the RFX-1 mix during the production process. As the substrate contains the right blend of rockwool and PU flakes, it has ideal proportions of water and air. RFX-1 is suitable for use with drip irrigation, ebb and flow trays, and watering by hand, and it ensures the plants develop healthily from day one. Three RFX-1 bags are packed together in a neutral cardboard box. This means each box contains 240 L of substrate!

Janeco-Light-Mix, 50 L Janecomix is an ideal basic substrate on which practically any plant can be cultivated. The slightly fertilised soil has the advantage of preventing even more „difficult“ varieties from being overfertilised. Apart from a minor dose of fertiliser, Janecomix also contains perlite to keep the substrate sufficiently aerated while simultaneously generating an optimum water balance. When cultivating in Janecomix soil, it is possible that you will not need to add any nutrients during the first 3 to 4 weeks. The soil mix contains enough fertiliser for the first three weeks depending on the number of plants and pot sizes. After this period, Atami recommends adding liquid fertiliser to the plant for an optimum result. Available in: 13-litre and 50-litre bags (130 and 70 bags per pallet)
