Ive read through this whole thread and really like what i see, i have some questions and info which may help. As far as circulation of nutes i will give it a go since i just cant stop thinking about it, use a submersable pump in the pale with out a plant(your sump bucket),plumb it out above the water line,split it into how ever many buckets you have going back into the original fill fitting and all buckets will recieve the fresh nutes.As they fill the equalizer (lowest) tube will return the nutes to the sump bucket. Only use a sight tube on the sump,connect each bucket at the bottom only once,if you have more than two buckets be creative with tees so you dont have two holes in the bottom of any plant buckets. Maybe some check valves to keep nutes moving in only the right direction. Seems simple to me, but if my simple mind is too stoned for my own good let me know. And in 21 pages im yet to hear one person even talk about flushing their plants prior to harvest,Did i miss that? I got more but ill see if this helps first.
