<"You can">, but you need to cap it with something, as its very light. I'm not sure how well it would mix with soil if you want a walstad type tank, and it produces a lot of tannins.Hi can I use cocopeat as a substrate in my low tech tank ?
Thank you broHi all, <"You can">, but you need to cap it with something, as its very light. I'm not sure how well it would mix with soil if you want a walstad type tank, and it produces a lot of tannins.
It might be worth adding a little bit to some water and looking for a rise in conductivity, if you get a steep rise your cocopeat was either insufficiently rinsed at source, or has fertilizers added.
