I was reading that in order to equal one decent HID light, you need a panel of like 52 LED grow bars. One LED grow bar goes for $150, so that's $7800 vs like $300 for the HID. You do get greater bulb life, but 52
led bars, with three light clusters per bar, is going to take up quite a lot of space, so there's absolutely no real advantage. So don't waste your money on LEDs.
That's one way to look at the situation...Quote:

Ah yes I see.
And here's a pdf that explains a lot

www.ledgrowlights.com what do you think?
check the specs on the bulbs
They look great, but I've read the information (couple of months ago) and my conclusion, was the HIDs are better right now... my 2 cents..Quote:

Dude, if you do it, please keep us posted... Very interesting to see your results.Quote:

lumens are the measure of light according to the human eye.. not the plant, so you can't go based on that.. i dun understand how u can say they ahve no business with workin mary j, when they've worked on numerous plants.. they deliver more of the spectrum... i HOPE u read the other LED threads, we've been researchin this for a minute..
this is all experimental.. its been proven to work on other plants, and they're using it in space.. that SHOULD be proof enough that they should work on a mary, its not a mutant ninja turtle, its a plant..
