I am lookin into building two grow boxes one for veg and one for bloom of course. I have been reading books and various threads for reseach but i have a few more distinct questions. I have a 430w hps light that was loned to me by a good buddy. Besides this light im startng completly from scratch. I was wondering which box should i use my hps for and what size should the box be to ensure it won't burn my plants. I only plan on using 4 plants at a time for a bi montjly perpetual grow. Also with a light of that size what would you guys suggest for air flow? And my last question is what type of light/lights should be used in the other box that im assuming will measure 2x2x3 and will be adequate for 4 plants. If anyone could maybe point me in the right direction of a popular thread or just help me out if you kno the anwsers..Thanks in advance
