I almost forgot one of the best details of this grow room design .. see the screen .its 4 inch but it is one piece and hangs down on wire . when the grow finishes the lights are as far up as they can go . so I cut off the harvest and then rise the screen all the way up to the lights . I have a float light in the room so I can turn the grow lights off . this lets me re set the buckets clean them and re load them and then just lower the screen back down to the right height and then lower the lights again .. so I never remove the screen from the system ,its like a large printing press .. harvest ,clean and reload ... talk about easy ....this is a great design ...and nothing can SCROG faster !....lol
