Well newer models of LED are getting better and better, there is an UFO already putting out more PAR rating than a 400W HPS (290 PAR watts vs 110 of HPS) plus 12000 Lumen that's outstanding for a light that really draws 90W, I'm doing a test run as I want to see if this lights are able to grow buds. They already grow plants better than Metal Halide IMHO. Check it at my sig.

?? What the help are smoking, par- photo active radiation, is a measurement of active light wavelengths, while i have seen many LED system with a higher red band par rating there is still no evidence to support that an enhanced par spectrum not backed by intensity is of any additional value. And growth vs MH is a big claim cause it all depends on what size light u use, i can say for sure my 600 mh will beat any current 90 watt led system no questions asked.
but i really hope that in the future it could be, cause damns that would be sweet.
edit: a 400 hps puts out 55,000 lumen so yea the led might have better par rating but still dosent have the intensity to stack those heavy buds, also most led light have a shitty penetrating rating but that can be overcome by scroging so its a wash.

I can't agree just yet, I'm very skeptical my light would outdo a HPS in flowering thus the test, but you don't have to scrog if not wanted just pick nice stocky bushy strains and grow single colas. Furthermore I've proven to myself LED is better for vegging than any other indoor light source (I don't know yet about Plasma). It's like you think I don't still use MH to compare for myself....Anyways I'm not trying to impose, if you wanna know for real, try it.

The only thing holding me back is the upfront cost, also answer me this, under my 600 i have vegged 20 plants for 6 weeks in 3 gallon pots with out issue, can one 90 watt led system do that?
Edit: forgot to mention, Plasma is meh at best, one light will do a 3X3 zone at around the same intensity as a 600watt dual arc bulb, but in flower it just dosnt have the penetration, and that is still where LED falls flat, its drop off per foot is far greater than HID or MI. One of these days Ill try an LED system but since the difference between my 1000 watt and a 200ish watt system is only about 40 bucks a month and I allready have a HID system its not really worth it

a 600 for me is $150 a month just for 12/12The only thing holding me back is the upfront cost, also answer me this, under my 600 i have vegged 20 plants for 6 weeks in 3 gallon pots with out issue, can one 90 watt led system do that?

youre a lucky pup. europe as shitty prices compared to you guys for electricity and general price of living. thats whats makes LED more of a real option for me. Still.. I can get cfl's of the same wattage and probably similar results for much cheaper
Never heard about that. Only going dark for a couple days at the end.

wherever you heard that its wrong
only time you should be switching back to veg is if youre re-vegging, which takes long than 48 hrs
48 hrs of complete darkness maybe youre thinking of
