Hey guys, I want to power 5 of these on their own, the strips themselves say 700mA but the data sheet says nominal 960mA with typical forward voltage of 20.3V. So do I want to wire them all parallel with a current supply that will produce 3.5A to 4.8A and doesn't go far above 20.3V or do I...

Did you not see anymore the rest of the way through flower? I was just hit with thrips across my whole grow... I have another month to go for my plants closest to harvest... I might cry.

I realized I had the boards on each driver wired in parallel on accident, I was just looking at a diagram and not thinking. They're easily together pushing over what I need now, I wasn't expecting 315 from one driver I was measuring them together.

My 4 qb288 V1s at 320 watts seem to be doing good in my 3x3, there's still a month to go for these peanutbutter breaths. Those look nuts for 135w in a 2x2, what strain is that?

I bought some seeds from them a few years ago and the critical kush was delicious. Didn't have any issues.

Im considering building a rig for my 2x4 foot tent to replace my t5 lights... think 8 of those 4 footers would be enough for a 2x4 tent? Could adding a few 470nm strips (if I can find them) be advantageous? I see that's what the HLG b-spec boards use to supplement them.

I've been using a space heater in the room with my tents the past several winters, this year I'm putting heat mats connected to temperature controllers below the drain trays... I've had other people suggest this option to me before, maybe it would be a good option for you as well.

It's like the YouTuber integza says, "why buy something when you can build a way crappier version yourself?"

I just bought a bunch of these on a whim to add some to my weaker flowering light then realized they are supposed to run at a much lower current than the qb's on the frame... I already ordered heatsinks for them too lol (on a side note, I was able to buy heat sinks for them from heatsink USA for...

And gals

Sorry guys

I thought the constant current drivers would push more juice than they are... turned all the way up they are only pushing 269 watts... each driver is pushing two of the light panels I was hoping for at least 315 watts in here... I'm not sure if I just need to add some supplemental lighting or...

I finally put together a frame for 4 qb288 v1s that I bought up when they were cheap. I've been a busy guy, haven't updated anything in a long time... These plants were under the 4 qb 132's in my profile Pic which I chopped the frame on to make it fit in one of my 3x3s instead of a 2x4. They are...

I've never heard that 60% humidity is so high you should be concerned about it. My humidity stays around 60% all summer long with a dehumidifier running 24/7, Idk about anyone else but it's hard for me to get much better than that with these great lakes surrounding me. You should be fine though...

I noticed today one of my branches was dying, thought it was bud rot at first but I didn't see the fuzziness I usually associate with that so I clipped that off Then I noticed some of my other branches have kinda the same brown look to them at the bases Are these branches done for? The tops...

I sprayed them pretty well with neem oil and pro-tekt last night and was surprised with how many mites still seem fine today, will it hurt to spray again today or should I wait another day? Im kinda bummed to find out the main ingredient in azamax is the primary compound in neem oil, thought I...

Damn, 4 weeks? I'm about to try it on some plants for the first time, early/ mid veg... Dont think I can let em all go 4 more weeks, they'll out grow my space! Hope I can completely kill these shits, preferably in under 2 weeks

Just installed it, this thing's a lot louder than I expected lol

One of my plants has leaves that are crazy jagged, look about like shark teeth. I think the plant is plenty healthy, it's a feminized zkittlez and its right next to two other feminized zkittlez that just look like any other plant. Thought it was kinda cool figured I'd show you guys. Yes I...

Hell yeah I'll look into that permeate pump, maybe I can pick one up at the hardware store on the way home today. Last time I tested my tap water it was around 380ppm and when I sent it into a lab to get tested it had really high levels of nitrates. I'm growing in coco coir pretty sure I've...
