OK, I'm going to tell you anyway.
Results with LEDs usually mean slightly less dense bud and just slightly less wgt, but more trichome production and increase in potency. Blind taste testers have always been able to tell the LED stuff was better. (sighted testers have not been used yet)
Another plus with the LEDs, no need to run duct work and use (in my case) a 400+cfm fan to cool them (more electric use). The LED setup raises bloom room temps a couple of degrees only above ambient. The other big plus, with less radiant heat generated your medium won't dry out as fast, instead of watering ervery other day the LED plants go a week. But that's not all....because less moisture is cooked off from the pots the amount of salt build up is reduce tremendously.
Here's a couple of pics of some LEDs. How about 2 TI problooms for a total power consumtion of 660watts vs 1150watts total for a 1kw HPS.
See, a side by side comparison of LED and HPS. I've actually used both.
(I also use T5s, love to overdrive them)
