New to SFG and am planning on building one real soon, hopefully. Was curious if any of you have experimented with building an SFG over a pond w/ fish (tilapia, koi, etc) and creating co-dependency for hydroponics.
I searched around and came across a few people who have done this - it seems like an interesting way to do it. But I'm guessing you'd either have to change the ratio in mel's mix or use something entirely different to grow the plants in.
Any experience with this?
