After thinking about it all day i decided to just experement with very small pumps. should work as long as the whole system is level. im going to try it with the return line. just need it to circulate. dont need a toilet flush.. my idea with air might work but its way over my head.
and i just wanted to thank all the ppl of this fourm, after months of reading im on my way to growin fat nugs. ahh but who give a S@#T im just talkin to myself anyway.
