Replacing all ten power supplies on my 2 290's still burned plants, just delayed it a couple weeks, so I understand the frustration. I'm gonna try to do some vegging with them, or supplemental light for the 1000's. We'll see. I don't have very high hopes.

Either way, I still like seeing the results WeJuana. Thanks for keeping it up.

They work great for vegging. They seem to stay nice and cool and take up less water than T5. I will let you other peeps with lots of time and patience figure out how to use them for flowering, haha. Thanks for sharing.

Sucks doesn't it?
When Companies like Lumatek and Hydrofarm put out equivalent products with real warranties that we can believe in.. That is the day I will buy a big ass expensive LED grow light. These run of the mill, fly by night Chinese outfits with their hands outstretched for cash... they scare me the most.

Same here -- that's why I ended up going with Blackstars -- decent but not the best warranty but way less expensive. I figure by the time they go out I will be wanting to upgrade anyway

I'm quite happy with what my blackstars have turned out.

I just grew a 2 3+oz plants and one 4oz plant under blackstars - got over 2oz off of a 1.5' tall plant. I assure you they are not shit. You need to reevaluate your technique.

Id agree with you Ive had no complaints this far and im on my 3rd round!

thats how I feel if I get a couple years out of the light im happy if it pulls down a 5- 10 pounds it pays for its self 10X over

Damn straight -- even the blackstars are not cheap, but far less than street prices to buy. Mine paid for themselves the first plant I harvested (over 3oz)

I agree, on my first LED grow using a BS180 (and a PG180 for the last 3 weeks) I grew two plants, both under two feet tall (including the pots!) getting me 92g and 72g dry respectively, off each plant.

I vegged using my Spectra 290 V? 2011? and had good luck but seems like overkill. Not sure what to do with the two 180's I bought at his ridiculous prices but will have to chalk it all up to fking education, I am using aan air cooled 400 hps w 150 hps supplement and after 25 days they look like they should. BTW, Irishboy is on Bubbleisious (sp). as are some other die hard spectra users.

I'm glad you all stuck around to see the round through! I am going to do a blind sampling with the yield soon and will give the "smoke report" results when I have them. Next harvest I am going to total the yield for each tent and then divide by the number of plants in the tent giving an "average weight per plant" figure for the lights. That will be a little more conclusive in my opinion.

Then on to the next round.. :leaf:

That seems like it should be a good veg light. My 2 x 150's do a fair job filling a 4 x 2.5 space although the footprint could be a bit bigger. There's more stretching than with my T5's but they're cooler and less wattage than the 415w unit I was using and the overall health is fantastic. I still have 2 or 3 more 180's sitting on a shelf collecting dust though, I will set a friend up with one for a veg light if/when they are looking to start a setup. Grats on the harvest WeJ, looking forward to that blind taste test!

wej do you notice any bleaching from the black stars?

No none at all. I will get another update video up shortly to show the progress of the current plants

What height do you have the bs at? 2 strains that I have under it are bleaching (yellowing) but could be a ph or deficiency issue I need a new ph pen

Bleaching or yellowing? General yellowing isn't going to be due to your LED. Yellowing or yellow spots on the upper leaves that looks like HPS bleaching is bleaching due to the light. Mg-deficiency like pattern on upper leaves is due to LED too close. Mg deficiency yellowing at the bottom may be due to LED (need more mg) or may be pH issue. General yellowing at the bottom or overall is not due to the LED.

Fucking asshole. Fuck him and Irishboy (i noticed his ass has disappeared).

I haven't been on the forums recently because I've been busy, but so much for his 5 year warranty. I've been dealing with lack luster results from the GLHs for 3 grows now and now have burned out LEDs. I emailed Mike and he said it was a bad power supply. I have the 2011 290w and never got the turned down power supplies. I asked him to replace the lights and he said it was a bad power supply so he sends me 2 power supplies. I experiment with the new power supplies one by one and it still didn't fix the burned out LEDs. So now I'm stuck with two piece of shit $700 lights and a worthless warranty claim.

Just FYI, and being fair. Mike has answered my email and told me to send the panels to him (at my expense of course) for him to see what's wrong. I will update when he resolves the issue.

I bleached plants with my blackstar, at least 12'' from canopy .. also it stays lit now which kind of sucks when trying to flower, I will probably just get rid of my bs 240 , anyone? real cheap

I have issues with bleaching getting about 6-8 inches from the 240, I like to keep lights at a 14-18" range depending on the strain.

It's between 16-18 inches away from the canopy and its giving a nice even cover for the 4x4. Can you post pics of your plants and maybe I can give some insight?

if your light is staying on dim when timer turns it off its because the polarity of your house is different than the light. just pull the ground pin out on the light plug <--- only due this if you are running them on 110

How does removing the ground which is for safety, change polarity. Sounds like either a polarity issue in the home (check all plugs with a polarity tester) or timer is bad. DO NOT CUT GROUND PIN OUT,

IMHO

ground pin is only there for 220 110 it does nothing at all not my imho fact
