Cocos Premium

Cocos Premium is a fully buffered coconut substrate. Unique about all Plagron coconut substrates, is that they are more buffered than comparable products. Unwanted salts have been flushed out during the several buffering steps. This guarantees that the nutrients in Cocos A & B can be absorbed under optimum conditions.

Because Cocos Premium is fully flushed and buffered, a low EC value is guaranteed. It is a given that you are growing with a coconut substrate that is clean and pure. Since all unwanted salts have been flushed out, your plant is prevented from having problems absorbing nutrients during growth and flowering. When Cocos A & B is given in the right dosage, it can be absorbed by the plant properly. The low EC value also prevents a calcium deficiency.

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 Premium has 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.
