Great grow man I been on here for a awhile back when blackstars first started. Whoever says blackstars wont flower are crazy iI pretty much perfectted my setup I have 2 240w flower blackstars and a 300w chinese led panel. The best I ever did with my setup was more than 2 ounces dry on 1 plant in 1 gallons ! people said I was full of it but if you check my post I had pictures . Now im pulling just shy a half a pound with my setup with about 3 plants one in a 3 gallon and 2 in a 2 gallon pots im using AN and molasses. I use to just use no name nutes at home depot im using promix hp great stuff could use a little more soil mix tends to dry quick. Anyway great job man keep it going !

@Endur0 - Not too sure, as I haven't used a Diamond series before, but the Blackstar seems to definitely be better priced for the wattage (3w bulbs and around 135w actual draw)
@surgedup - Thanks for the encouragement!

Link? I've been compiling some info on these LED retailers. Would like to see these pics with 2.5oz. per plant on LED.

Looking good WeJuana. My bet is on the Spectra. Although I've seen reports of the 2011 models not being as good as 2010. It is discussed here.

Are you feeling like you are wasting money doing this experiment? I mean, since you are not scrogging you could probably have at least 2 plants per tent without affecting the yield of each plant and get double harvest out of the setup? Or since it's only day 10 you are expecting them do get much bigger still? dont get me wrong, I like the experiment!!! just wondering

I just set my UFOs in my main room as supplemental lights until I finish the dresser... Can I leave the LEDs on for 20hours? I read somewhere 16 is about the max you want to leave your LEDs on, is that true?

yes I guess I got ripped off with my NEW - Diamond Series LEDs - Extreme 3w LED Technology... 400$ with shipping for a 100w! How long has the blackstar 240 been for sale at 279!? mine was 295$... I guess there is 11+ Wavelengths of Color Output in the diamond...
I have two panels from advanced and im very happy...never once have I felt ripped off.

Good to know!! I am not worry about the quality of the light... I just started to think I could have gotten twice the wattage for the same price with blackstar! I didnt know about 3w chip until I got on their website and that is what sold the light, so I couldnt resist!!

you know the answer to my question anyway, can you leave LED lights on for like 20hours no problem? thx

Ditto. I've got two Advanced lights and I haven't a negative thing to say about them... keeping in mind that I'm just finishing my first grow.

I only wish my growing skills were on par with my lights' capabilities! ;-)

No problem with leaving the lights on that long. I sometimes veg 24/0 and I've done autos under 20/4 most of the cycle. No issues at all, they have very long lifespans and excellent heat dissipation.

Glad to see happy advanced customers. Have any pics or journals to view? I always enjoy seeing what others are getting done with the same lights

I don't think you got jacked by advanced. Haven't used them but did a lot of research on them. They were on my "I would buy these" list. The blackstars are a bit less expensive yes - but only covered by a 12 mo warranty as opposed to a 36 from advanced. I read that older model blackstars - can't speak from personal experience and newer models may have chanced, but heard older models were not using finned heat sinks which could lead to overheating issues later on down the road. The 100w from advance was about $300 right? The blackstar 240 is essentially somewhere around a 130-140w light. Given the warranty alone I wouldn't be upset with your purchase.

I've been leaving my leds on 23-1 now for a while - its totally safe for the light.

I don't at all feel like I am wasting money, because knowledge is more valuable to me than having extra pot lying around. I grow not for profit, but for personal use as a patient.
I have enough to get me by to this harvest, and in the future I should be harvesting perpetually, as the clones are about ready to pot today.

The tents will also start filling one quickly once I start entering in new plants, so the space will be utilized soon enough.

If you have a comment, feel free to shout it out! No worries Endur0!

I've left my LEDs on 24-0 for over a 2 week period without any issue. As long as the light is working properly with the heat sink it shouldn't be a problem.

Agreed I ran my panel (different brand but 3w) for 24/7 during veg. Make sure you don't exceed your suggested operation temp and it should be fine.
