I've been on LED since I decided to grow my own medicine. Since it was all premeditated and stuff, I made sure I didn't start off half-cocked. I did anyway, but that's just because no matter what you think you've covered in your plan, there are always unexpected things that force you to change plans.
I'm using the Theoreme Innovation solution. Crazy French Canadiens... I say that with love; I took French in school instead of Spanish; I'm in California. If you want to learn how to chop wood, you don't use a plastic axe. Get a real, researched, designed and engineered LED grow light. Mind you I've never compared mine to another light, so my writing here is biased.
I use CFLs for veg and the TI SL-600 ProBloom (ProBloom is a mix of spectrum that includes UV, IR and green and orange, in addition to the reds and blues.) LED to flower my ladies. I'm about to purchase a second one to mount right next to it on the mover. The only difference between the plants I grew indoor under this light and the same strains out in the back yard was in the yield. The indoor was super sticky and fragrant and potent when it counted. The outdoor was... the same. But the two plants outside gave me about twice the final yield as the two indoor plants did. (The four plants, all clones from one mom, vegged identically under 6500K CFLs (12x23W) for about 6 weeks. Then they were separated.
There is no replicating Ra.
But I'm about to get close. There's a new TI-600 on it's way soon; just waiting for the wife's tax return. Mounted side-by-side as one unit, we'll have what would be claimed to be equivalent to a 1200W HID. But our two lights will draw 660W in total. I can't wait. It's the reason my plants seem to love the veg room and get "skinny" in the flowering room. I was trying to spread the photons too thin with several plants in there at a time. Even with the mover--which should be required equipment for anyone--I was asking too much. With this second light, I'll be doing much better.
Well, I gotta run and watch a movie in the other room now. So... I'll be back later... Check out my picks. They're not recent but they're relevant.
Peace.
