There are best case scenarios for many of the different lighting options. It's not a "One size fits all" or "This is the best" situation. In fact I'll continue using florescent high output T5's for starting seeds and vegging because I think they provide great results, you can get the light right over the plant from early stages and prevent stretching in veg. I don't think I'll ever switch from T5's for starting seedlings.
Anyway. I'm about to have some of that PCK/Durban cross I made topped with some dry ice hash. That's the reason I grow. I could care less about some silly light spectrum chart and how many grams per watt a light yields. I do just fine with my antiquated 600 watt HPS. I give over half of what I grow away anyway. In my case there is no reason to expend any additional cash to purchase some new light because it uses a little less power and doesn't put off as much heat. HPS for me for now. I can buy a new LED setup or I can use that money to go on vacation, maybe buy some 18 year single malt scotch. My money is better spent on other things than fancy new lights.
As you were...
PCK/Durban Just one of my many offspring. I'm focused on growing weed not what light people use. And by the way, this was grown under a 600 watt HPS and turned into fire.
