I wholeheartedly believe led are more than capable to replace any other light for vegging. I would take a bs240 to veg plants over my 600mh, partially for the power savings, but mainly because I know it can do the job.

The 500w one is the sweet point on price over the 600w, though I went the route of going with 2 x 240ws to get better coverage. LEDs aren't great for sidelighting (or penetration) in general. They also have a new chrome series one with 7w LEDs you might want to look into too but it's real new so no grow results yet

Thanks matey i was sort of thinking that they wernt that great for penetration as all the pics and vids i keep finding are of smaller plants. Be interesting when the 7w diodes are more widely used i think leds are definatley going in the right direction thats for sure :D

Pretty sure they don't use 7w diodes...in fact I've never seen or heard of any led grow lights that do. Where did you guys hear this from?

My Kessil is frying my plant. It is making my Sativa a squat litle bush. I think it is penetrating the floor!

ooo so how long has that been under your kessil? are you going to flower under led too? was just thinking that it would be cool to have it bushing in veg, then flowering under hps would really be mental :D

I know! I keep seeing 600W and 1000W HPS results and I wonder if I am wasting my time. But this Kessil is doing a great job and no heat. I am only growing one personal plant and so I think the heat and overkill of an HPS right now would be, well, overkill. I will put link up here so you can see my growing pains with this plant and light.

I feel the same and yes, they will. They will also do it with less stress on the plant. Only caveat with the blackstar 240s for veg in my opinion is coverage. I would say 1 blackstar is probably good for about 4 sqft of solid coverage underneath for older plants... 9sqft for small plants/seedlings. So if you've got a bigger veg area you are going to need more than one. But they are fantastic other than that. Really loving mine for veg... still waiting on flower results.

Young plants have the same rules for LEDs as HID -- light needs to be farther away for younger plants. For veg you definitely you do not need the LEDs as close to the plants as you can get or you'll get problems. Your pic actually shows the lack of penetration -- the issue with LEDs is those dark shadows under the leaves like you see in this pic. HID the light is more scattered and you don't get the same amount of shadow underneath leaves as LED. That's why scrogging/trained canopies seem to be the way to go with LED. I got 4 LEDs spread across my canopy for more even lighting and there are still darker shadows under the leaves than there would be with HPS, though not as much as just 1 or 2 LED lights.

look into buying a solar storm there well worth the investment! i have 2 of them after signing up for a growers feed back and so far theyve beat everythiing ive put them up against in veg. im a few weeks away from flower but im confident that nothing will compare! the owner is an elctrical engineer who lives in cali and specifically makes his lights for mj plants!

Damn! Yall put a few pages on since my last visit lol. Just read it and caught up.

@wraffer - I will be able to conclude of LED is a viable replacement for LED after this round of testing.
@curly - the website looks like it was done well.. but that's the most ii would dare to speculate on. I leave the rest in the power of what the light can do itself and I wouldn't venture to say without being able to test it.
