hey all, I some what of a newbie. I've grown before but only with natual light which didn't net good results. This time I want to use artificial lights and I'm not sure what's a good deal(moneywise) At Discount-hyrdr.com i can get a 400w HPS econoswitch w/ horizontal reflector for $220 -HPS bulb included fully wired. With this model you can use 400w HPS or 400w MH bulbs. I figured this was more econonmical considering the cost of conversion bulbs. What do you guys think? Also what is the best reflector? I have a space about 3'x3' with 7' ceiling. I only need to grow a few plants nothing commercial. Any suggestions? Is 400w too much for the space I have? What would be the best lamp size?
