Ok so ive read enoguh about the subject and most people agree mh increases potency and density. So i thought as you cant find a good comparison on thc i would do one as im currently doing it.
The room is 1.5mx 1.2mx 2.4m so its a nice rectangle which is very tall. I have got 1x 400w mh bulb and 1x 400w duel spectrum hps and both are in cooltubes connected together by good old tape (what else would i use)
The grow will be a 12/12 grow and im yet to decide which plants to show as i have regs so watch this space and ill be back with pictures of the plants, ill get pictures of the set up tomorrow.
Any comments and advice, ideas welcome. lets put this to bed which is better mh, hps or the middle where they grow mh and hps, the floor is now open
