Hydroponic growing with stable pH valueFind a store
Plagron Cocos Slab is the ideal substrate for growers who prefer to use a pure and natural product. It is natural and completely buffered with stable pH-value, in contrary to other hydroponic substrates. Cocos Slab has a high water retention capacity so you can give less water. Cocos Slab meets the most stringent quality standards, does not contain any fertilisers and is suitable for all types of liquid nutrients. Cocos Slab produces the highest yields in combination with Plagron Cocos A&B and the additives from Plagron. Our Cocos Slab carries the RHP quality mark.

Cocos Slab is easy to use because you can grow your plant directly in the slab. This is because Cocos Slab is especially pre-shaped for proportional root growth and has ready-made drainage holes.
Cocos Slab is a fully buffered coconut substrate with a stable pH value. Unique about the Plagron coconut substrates, is that they are more buffered than comparable products. Unwanted salts are flushed out during several buffering steps. This guarantees that the nutrients in, for example, Cocos A & B can be absorbed under optimum conditions.
Because Cocos Slab is fully flushed and buffered, a low EC value is guaranteed. Therefore, it is a given that you are growing with a coconut substrate that is clean and pure. All unwanted salts have been flushed out during several buffering steps. This prevents your plant from having problems absorbing nutrients during growth and flowering. When you give your plant Cocos A & B in the right dosage, it can be absorbed by the plant properly. Because of the low initial EC-value, a calcium deficiency is prevented. For the correct dosage download our standard 100% COCO growing schedule.
The high quality of the Plagron coconut substrates is confirmed by the RHP quality mark. The RHP quality mark guarantees the correct quality requirements and sustainable origin of the substrate. For example, Cocos Slab has an excellent water retention and is free of sand, weeds and pathogens. This means that Plagron coconut substrates are clean and pure, and you can use them safely without risk to your grow.
