aeroponics chamber ideal dimensions

[ways2]

Have almost every piece to build HPA system finally!! However, can't decide on root basin. Had originally planned to go all 55-gal as sourced food grade new drums for good deal but have since wanted to do either a U or an A shape and possibly even a square vertical chamber!!! AAHHHHHHHH please help am going crazyy!!!! Liking the idea of using 6 mil poly and fastening it around a half-pipe skeleton, with holes cut out of 2x4 insulation that'll rest on top of the frame. maybe incorporate the irrigation piping into the frame as well but probably won't. Am working with 24 100 watt cob led's (barely received the holders,which don't exactly fit them as they aren't mainstream but we'll see if they hold true to claimed specs) running them using 8 meanwell hlg-240h-c1400a. not going to get sidetracked... would like to focus efforts into no more than 10' x 10' x 8' but can expand if necessary as the room is approx 20 x 24 x 8. Bought a tent that was not going to cut it so just went and bought all the wood and conduit to construct a mostly passively cooled room by trying a baffle idea have been thinking about. Kind of like a giant glovebox, using negative pressure to draw all the hot air out using a wind tunnel that's created whenever the garage door is opened at the right angle, along with the windows up stairs. It's awesome!!! Now if only can practice the patience to not give up! ARRRGHHHHH!!!!!! sidetracked againn!!! alright, back to the drawing board...... if anyone would love to interject constructively, please don't hesitate as am all ears right now.........sorry for the foggy details.... its that time of year again...... also in a little dilemma with buying some watered-down nutes that am now stuck with at the behest of the bastard who talked out of going with seablast from earth juice......it's another long story though..rather to focus constructively than spend time harping vindictively, i love to and will go out of my way to make more time for humility....
