You know I think you are right...I will give a try on an HPS set up. I've never actually tried HPS or MH I have only tried either LED or CFL to date. I want to see how much faster the plants grow and how much better the yield will be. I was reading an indoor growing magazine and they said even still to date HPS put out the best possible spectrum, you have to spend lots of $$$ to get an LED that will put out a spectrum even close to an HPS...so it may be worth a try, next month I will try it...see what happens I wont sell my stuff I will give it another shot, I will get better genetics this time, and ya.
well, I love HIDS, but in no way is it the best spectrum, LEDS have that in the bag all day long.
BUT a nice broad spectrum MH would be helpful, or a simple hps.
And how big is your tent? you can stuff a 400w in a small area, if you have ventilation.
Oh, and that darth vader is WAY overpriced at 290 an oz...
if you are in CA, check craigslist, people sell oz there for WAY cheaper and it'll shit alllllllll over that darth
just have your medical card handy
