Hi everyone. I know that COBs no longer inspire anyone but I still prefer them to SMD because I love DIY and having a lamp that can be repaired with two screws and spending 30USD if a single COB dies. I wanted to build a new panel with vero29 gen8 I'm going to put 6 COBs and was wondering if...

Hi, do you take any instrumental measures about that? So we could say quantum bar and board has more penetration then COB..or better sayd COB are more susceptible to panel distance?

Hi, could you tell me how do you calculate cct in that way? Nonody consider that marshydro adopts more smd than light geek so prob they run cooler and long lasting?

Hi, i know very wel what shane share on that migro "ranking" I mean the data claimed from geeklight about their new "plus" model. how can a light with "claimed (probably not actual data like migro's owner measure show about the 6bar / pro version 2.78 declared VS 2.27 actually measured) 630W...

So nobody comment so fake claims? I am a owner of this light but I do not love to be kidding. As on alibaba where they claim 3.03 µmol/j

I own the PLUS VERSION : they claim 630W of power and 1820 µmol/s (3.03 µmol/j) it is of course impossible and could realistically be 630W power 2.88 µmol/j ( 1820 µmol/s) ---> LOWER µmol/j value or 630W power 3.03 µmol/j (1909 µmol/s)----> BIGGER µmol/s value or finally 601W power 3.03...

I bought the new 8 bar model but honestly i think could had be a better buy the new eight bars model from marshydro..significative more number of smd at quite identical Watt and a lil less expensive..without inefficient IR and UV chip( even if I do not know about heatsink, specs says it should...

Hi guys. Hoping somenody could anwer to a little question Mini growing tent (50x50cm/19.7" surface) and I' m vegging with a kingbrite QB 3500K 90CRI samsung LM301H without any far red, IR or UV drive at 50W. I have got aldo a DIY citizen1212 90 CRI, 250W(50W each cob, active cooling) Citizen...

Well done! Same identical experiment of me!

Great post..old but ever gold. Thanx!!

Hi, it's the first time I hear this. Could you please argue this theory? does it apply to any type of LED (COB, QB) and brand? best regards

Hello, Maybe it has already been explained right there but I am not very skilled with your language and even less skilled with the theory concerned the air physic. If I reduce the speed of a small 187m3 / h extractor by a dimmer could I know how many W i may give to get ish 80m3 / h? I only...

Thankyou so much fpr sharing!!

And half an year later ....so NL as not smell/stealthy strain is just a legend? Somebody (ogecil) ever done a smoke report of peakseedsbc kushnorthernlight?

Hi again, I have another last question. Do you think can I manage 10 (mixed)EB strips whit a 200v cc driver? I already have six EBseries stripes, first generation. 22.1V at 700mA but i can not find any calculator, according to data sheet should be 21.7V run at 500 mA and 21.0V at 200mA.(I can...

hi guys. I'm going to buy at HLG-60H-C350B to drive 6 (in the future 10?)bridgelux EB series (not the latest generation)560mm at 350mA (without heatsink) Can you explain me why there are two difefrent version under the same producrt code ? one is the classic CC and the other one CC + CV(check...

During winter time people tend to forget monitoring the temperature of the pots during night time. Slow release fertilisers, as do all organics needs a temperature above 20C.... that's first time i read that, whi do not put this indication about temperature in your instructions? PS I know...

Hi, here is another really stupid question that I coudn't answer on my own. I Can' t connect a 18AWG silicon wire to bridgelux stripe solderless connector. I had try also to put a little layer of solder to make it more stiff but again wire doesn't conect to the board. Maybe i must pull or...

Sorry...i meant that one. It would be a seedbank from Canada. http://houseofthegreatgardener.com/wordpress/strains/ But i never heard about that. About dinamed as another seedbank(like cbd crew before change the Therapy description) they claim bullshit(and yes also candida has inica phenos but...

I'm ever more confused!! https://www.rollitup.org/t/vegging-with-3000k-90cri.936591/#post-13421099
