If using cocopeat or cococoir as a hydroponics substrate, you’ll end up with a big mass of roots after harvest. Some proceed to disinfect by way of solarization or even boil it in a big pot of water. Others re-use this media in their raised beds or vegetable patch in the garden. We don’t like none of those options. We believe in re-using and re-cycling as much as possible, including the substrate media. Buying new inputs every cycle such as rockwool or fresh cocopeat adds more costs that reduces your ROI.

COCOPEAT

By simply composting all of the spent cocopeat in a compostbin or sack, it allows the microbial breakdown of any remaining organic matter (roots, stem, leaves) and purposely promote the colonization of more beneficial bacteria and fungi.

FEED THE BACTERIA

At the end of every harvest, we collect and store the spent media in a compostbin. We’ll add a bit of molasses to feed the bacteria to allow fungi like myccorhizal fungi to mineralize the bacteria to end up with a primed substrate for the next planting cycle. To help speed up decomposition, you can use Effective Microorganisms (EM) or Azotobacter as an additive.

In a few short weeks, you can use the cocopeat again for the next growing cycle.

BIGGER YIELDS, LOWER COST

And by doing so, our suceeding yields keep getting higher and the taste quality markedly improves over time. Plants grown in microbially strong media have better plant defenses against insects and pathogens. And the best of all is the reducted need for the consumption of synthetic fertilizers over time.
