Have built a lot of these bad boys.. 300+. Standard 4x cxm22 and hlg-185h-48a. 272w of light, 16 for fans. Covers a 2x4 flower solidly.
Over a LOT input obviously: average about 1.1-1.2 gm/w. I've gotten as high as 1.7 with big pots, long grow time, hydro, co2 and big yielders. Not that i use...
Every time someone comes into these forums asking if the $100 chinese light is ok they get the same answer: NO.
you bought it anyways, and now you're mad?
Obviously you know shit-all about leds, but you know about these forums? You skipped everyones advice and then come here to bitch about...
Thanx for posting data. Its THE ONLY gm/per watt I've found outside of some limited growmau5 vids.. I want the DATA! I didn't bite on cobs until I had seen many success stories.. I'm VERY concerned at the lack of data on these. Anyone concerned about canopy penetration? I grow scrog and the...
Single cob to each fan. 4 per light. 2x4 coverage. 288watts. 1560ma or so.. sweetspot with cxm22's.. RELEVANT: You'll get more light in a 4x4 with these for 576 watts.. THATS 1900 watts electrical savings AND more light..
Those chinese (red) lights are the worst..Waste of elec trying to flower with them.. One use I found for them: replace chip. Yeah, its not a fun project, and you'll have to cut edge off reflectors in two places so your new chips holders have correct spacing.. cxa2540 is your match. If you're in...
Go do some reading. Figure out how cool you need your lights to run. Your vent/cooling situation will determine how cool you need to run.
You want leds cheap, you're building it. Period. Otherwise check CL for people building for you. Or get a warrantied fixture and pay up.
4x4= 8 cxm22 on...
One of the most interesting parts of the observation phenomenon is that it is unaffected by time.. They used solar lensing in a celestial sized double gate experiment and were affecting photon measurements that should have taken decades to relate. Quite literally the photon state which was...
Meanwell is worth it. But I have used cheap chinese drivers.
Things to know:
Their rated ma/watts: lies.
Their rated efficiency: lies.
Their rated voltage: generally true.
They do work however. 1400 ma ended up being about 1200.. that kinda crap. Figure eff is mid- high 80%ish..
I run some...
I think it's stupid af. But seen the vids too.
Biggest rationale: wash off powdery mildew. (Cervantes did it.) My criticism is : throw if fucking out man and improve ventilation.
Other reasons: washing off chems. A lot of knuckle heads using tons of foliars and stuff.. I bet the stuff...
Sounds like BS. Throw us a pic.
NEVER seen a blatant set-up. Plain sight shit WILL ALWAYS gets reported and dealt with. Period.
12 plant limit is MA as far as I can tell. MA police will fuck your shit up sideways with blatant pot violation- blasting is strictly forbidden too. A permanent...
Too scared to do things yourself + limited budget is not a good start.
Your english is excellent, have you tried viewing Youtube instructional videos? Quite literally positive to positive, negative to negative connections.. Not too hard.
Expect to pay 200%+ actual cost/ premium if someone...
