I'm biased, but hey here goes, forget the HID, HPMH, HPS etc go for LEDs, sit down with a calculator and figure out how much money you will save on the electricity, it will blow you away, also you'll have environmentally friendly weed, Happy days  |
I'm biased as well. Forget the LED's until they have been proven. So far every person I've known who have used them has been extremely disappointed with the results. Most say they work alright for veg growth but truly suck for flower growth. Until they get cheaper and more effective they should only e used as supplemental lighting in conjunction with a HID. Yes they conserve energy but that's a moot point if they don't grow weed worth a crap!
Just my opinion.
