Yea man , you need to come down when the weather gets a little better and do some trolling for crappie with me . I wear them out that way and it's a BLAST .
@steely07 , do you use any fertilizer at all ? I was thinking about trying the PVC route .
No, 0 fertilizer, 0 chemicals, just fish food, the fish waste is rich in nitrites, naturally occurring bacteria in the grow bed converts this to nitrates and the plants use the nitrates as food.
It's an awesome way to grow food, we have people here in Australia who live in very dry climates and can't grow plants because they waste too much water, but this way you only replace a little water now
and then due to evaporation.
Today in Sydney for example, it's 35 degrees F (95C) and normal gardens are wilting and dying like mad, but mine is on a 5 min flood / 15 min drain cycle, so when I get home from work, all will be well
