Here's my idea: One 400+W for both veg and flower....18/6 veg and then switch to 12/12 for flower.....how does this sound? If I could get some approval then I think that this will be the cheapest/easiest for me, for now atleast. I def hear ya Zoidberg, I stopped by my local hydroponics store this morning and WOW! As soon as I can generate some extra income, I will most definitely be doing some major upgrades. I feel a hydro operation coming on in the not too distant future! Also, yeah, I can keep the door open to the closet for vent. Should I leave it open all the time? Do I need to leave it wide open? Thanks so much, yall (I'm from GA, sorry about the lingo) are so very helpful!
