Has anyone out there tried to grow maryjane in their ap system? A friend gave me one to try, very ph sensitive and fish dont give it enough phosphorus I think. No Im not a pothead, I just thought it would be a challenge to try, anyone know more?
Several months ago I built a debris filter using cooler pads. It worked great but as my fish began to multiply and grow larger I went from cleaning the pads once every couple of weeks to everyday. Today I replaced it with a bed of 3/4" gravel. It sits in one end of the raft tank so it will be a continuous flow gravel bed. I'll add some worms too.
I probably should have asked this before spending 5 hours cleaning gravel and filling the bed, but I'd like to hear your opinions on this change. I don't plan to grow anything because all I want is the gravel to filter fish poo.
On the right is the gravel and the rafts are on the left
Well, the pH range for nutrient availability on the soilless graph is far below my experience as well. At least as it relates to AP or bio-ponic growing ...Which is kinda why I told David not to get too hung up on those numbers shown there...and that he'd be just fine with a pH in the mid 6's...I like to keep my pH just a tad lower than the range Sylvia or Murray suggest. At any rate, that is the chart David was asking for. Not sure what you mean by "going with David on this one", since it seems we're all on the same page
David, don't get too caught up with the numbers on those charts...A mature AP system ran in the low to mid 6's should be a plants producing powerhouse. (Besides the bio-filter precludes the systems ability to function at a pH of 5 anyways)...
Damn, thats a pretty low ph, 5-5.5? I guess it would affect different plants differently cuz my peppers are producing!
Yup, that about looks the one (on the right).
@Vlad. Is the the one you are referring to?
@David That chart is generally accepted to work well, but for soil. That is the soil pH chart.
There is a different pH chart generally accepted for use in a soilless set and setting. You can probably easily fin it in 'internetland'...
