i'm in the same situation; first grow; closet about that size

1.120mm fans are pretty small for that closet. the easiest way to go is just regular desktop type oscillating fans from walmart or the like

have you considered whether you're going to have a veg room and a flower room (take clones) or just grow one grow from seed to bloom?

cloning is very simple and that way you can keep growing constantly rather than start from seed all over. if you get a 10seed back you might get 4 healthy females out of that. if you take one as a mother, and flower the other three, you can take that mother and make 4 clones, then once you're done harvesting your first plants, you can take the clones (which have been growing for a couple months in your veg area) and flower them, and the cycle goes on and on. you can use cfl our flouro tubes for the veg section of the closet (you can make a little growbox for veg for instance) and use that hps for the flower section. that's just about perfect. the one thing you have to make sure is that no light from your veg section/box spills into your flower room, those flowering plants need 12hrs of darkness


the reason for having two growing sections, is A: you can be harvesting every couple months, and B: you can just use flouro's for veg, and hps for flower, if you just had one room you might not be using your hps for awhile in early growth, and it would just sit there


anyway, i'm trying to decide this very thing myself. i just have to make sure that my flower area is lightproof


oh, btw: i've ordered "silver pearl" nirvana seeds from seedboutique, and my closet is 2'deep, 6'high, 9'wide about. ventilation is going to be an issue so i'm going to have to be clever about when the closet is open for airflow (essential for hps, for veg with cfl, a little oscillating fan is enough as long as it's not in a closed box). i intend to flower 6am to 6pm and veg 6am to 12am; of course when starting out i'll just be vegging so i will have less light worries.

anyway, it's good if you can clone and not have to keep buying seeds. it helps you keep a low profile and it keeps costs down. and best of all, you know that you're growing females and don't waste your time on males. you'll want a new strain at some point, but if you're growing WW, it's so good that you wouldn't be needing a new strain too soon and if you have a mother, you can keep here while you get a new strain, and grow multiple strains without having to have tons of seeds and tons of males
