Well, I'm in the process of setting up my grow-room and from what I have managed to research and get advice on from the kind, experienced people on here, my closet measures 200cm(h) x 70cm(w) x 60cm(d) and I've got 2 x 42W LCF's for vegging stage and 1 x 400W HPS for flowering.I am setting up a closet grow room. The closet is wide and 25 inches deep.How many watt hps lights should i use?Its a pretty small closet so wondering if 400 would be too much and if 250 would do the job.Any help would be greatly appreciated.
I'm using a 600 HPS in a Rubber Maid storage shed thats about the same size as your closet. If I were you, I'd go with the 400 HPS. Like others have said, you'll need to set up some kind of ventilation though ... and have a small fan blowing in there too. Remember, the smaller the light, the lower the yield. Rule of thumb to shoot for is 50 watts per square foot of floor growing space.I would say its 45in wide,25 deep and 6ft. tall...dont know what other dimensions you might need.
50 watts per square foot would be a good starting point for flower, in veg you can go with less...say 25w/sq ft.I am leaning towards CFLs....so any ideas on total wattage?
