It's gonna be a growbox made out of PC tower (60cm height). I'm thinking about putting 6 LED bulbs inside - 3x20w 6400K (1900lm each) and 3x25w 2700K (2150lm each). All diffusers are gonna be removed from bulbs, all bulbs are gonna work all the time. Can't get any CFLs inside, they're too huge. Can't get a bigger grow box either, nor can I buy a proper LED grow light, so I have to work with what I have. Do you think it's gonna work?
In a word, yes. However, in a small space, heat may be an issue, possible light bleaching. Now this all depends on different factors. Since the lights will be on constant, I'm assuming that you will be running auto flowers. You may not get a super yield or be super dense buds, but it will grow weed
