BOX PAREMETERS Width: 10inches Length: 20inches Height: 20.5inches im doing a SCROG grow. i have a rig of 4 compact flouro bulbs wired into a mechanical system, all hung from the lid of the grow box. the lumen output of each bulb is 2900 and they are 45 watts each. very very bright. so i have 4 currently, @ 11,600 total lumens. If i do this on a scrog grow in a grow box, will i yield enough? i want to use these for the entire grow. I may rig 2 more of the same bulbs into the rig and get a total lumen output of 17,400. I did some research and thats more than some 150 watt hps systems. i do not want to use HPS or MH because of the heat out put, this is a secret grow and i want to be incogneeto about it. will i yeild a good harvest with 17,400 lumens on 2-4 plants using SCROG? PS. is this equation correct? Square Feet: 1.38' @ 11,600 Lumens Footcandles (fc) = 8405 Lumens per square foot. @ 17,800 Lumens Footcandles (fc) = 12,898 Lumens per square foot.
