Being new the grow, I am interested in finding out which light system produces a better plant. HPS with the ballast system or LED with different colors? I went to one website grosense.com and looked at the prices for either system and the different wattages. Just wondering which does better for the dollar investment. I have a 4x4 enclosure.
With LEDs you'll have fewer heat problems, but watt for watt, they are usually more expensive. I use LEDs, and am sold on them.
