Ballasts are in another room where I have my mothers, veg , clones, water and timers. They do power those outlets which energize the hoods
Word 10kw isnt much compared to the giant od plants Yea If you were pulling 1 lb per light rooms, but I am able to pull 20 lb from my 4 4x8 beds....20 lb of indoor is good any time no matter what you having going on....I just am keeping it under 99 now that things are starting to really ramp it up out doors....i would love to give beds a try just alot of medium makes urban farming a drag when it comes to disposal of rootballs, If I was to flip this room again, all I would need to do is pull the MAIN root ball of each plant, hit the beds with an electric tiller, top the beds off with a couple bags of soil a piece, some Dr Earth 4-10-7 , a little castigns, and some Calcite Lime and Gypsum & I'd off to the races for another grow..The root balls from this room would take up MAYBE 1 Large contractor bag.. when i set up an indoor room at my outdoor spot i can give it a shot...its be gonna be a mini version of your room 3-4 lights on each row with the mh in the middle..gonna wire my outlets on the top too...so the bulb connects to ceiling,and where are the ballasts? In another room plugged in to a power board that sends the juice to the outlets in the ceiling. What you're missing is that I've taken the Lamp Out cord from the ballast, put a regular ol' 15A 240V plug on it, and plug this in to the receptacle board in the same room as the ballasts...At the other end of each one of these receptacles that the Lamp out cord plugs in to, is another receptacle (the one in the ceiling) where my lamp plugs in...Basically what I did was make very fancy extension cords
