HPS are just more efficient than MH. I find your point irelevant... Look at CMH grow. If i were to compare a 50% 6500K vs a 3000K 36% efficient light source maybe the flower would be greater under the 6500K ?! I flowered under 4000K and I can tell you flower were dense and big. Now I put half...

@nevergoodenuf So you said you ran them in parallel before without any probe. What driver was it and what did you put with them ? Did you consider them like an equivalent driver model enabling choosing your led ? in theory I know you can add as much sources as you want in parallel as long as...

Well right now I am about to try cooling 200W of vero 13, 80mm fan, and about 20cm/W cooling.

@ Seriousbuds I have designed a lamp for a 2x4x5 recently, If you want to go cheap : 2 arctic cooling or any other good CPU cooler, 2 LPC 150-1750, 2 vero 29. Plug the 2 driver in // and then the led in serie. It would give you aprox 315W of led at 37% efficiency (veros driven @3,5A) for about...

Hi guys, Just wondering, have you ever try to cool with less than 30cm/W in active dissipation? I am right now at 90cm/W in passive but using the fan for plant to cool the lamp. I have a piece of heatsink laying around and it should be abe to cool 120W at 30cm/W do you think a 20cm/W active...

@EfficientWatt Thanks for answering I found it at TME, the only draw back is I can't find the ELG in 2100mA over there... I needed it for 2 vero 29. 40$ is not that cheap, you can find a 200W driver HLG for 50$ so i bet there are still the best for anything under 1400mA. Thinking a bit, I might...

Hi all, Can someone lead me to ELG 150 2100mA for cheap ? I can find any for less than 40euros... I saw some say we better go with ELG instead of LPC because there is only a few $ difference but there is 15$ difference for the best deal i found. ELG would be killer, because I have been using HLG...

Hi everyone, I have been growing in a 1m2 box using only 200W (HLG185C500) of vero 13 4000K. Now, even if the result are high in terms of g/w (1,4 up to 1,7 in Wilma) i would like to change my set up. I transform my light so that it can fit a 2x2 box and plan on giving it to a friend, I am sure...

@ Gator mixing ozone with carbon fitration can be dangerous: CO gaz is created and carbon can heat up till burning. wouldn't advize so...

Hello guys, Nice experimentations ;) Ed said this a few years ago. EDIT: I put the article before but I realised in page 2 it is already quoted. Weed is good :) Also, someone tried it and it made some plants becoming hermi but no real improvement and they spend way more time to pass in...

Hi Captain, I think I will burn a little joint and watch your grow ;) 3 days and already showing pistils ? that sound very good...

Apparently ideal one dissipate heat because they are in metal... But they seems not to push a lot on the cob, so the contact between the heatsink and the cob might not be complete. TE holders seems very good, the only things is you will probably have to glue the lenses as I can't see any adaptor...

Btw, the seed we grow are generally selected in europe or America where the sun is less powerful. Perhaps by doing the selection the one which performed the best where the one needing less light and so we kept them. Landrace can undergo harder condition including dry soil, high temperature and...

little up, Did anyone tried to use a reflector on this TE-connectivity holder ? they seem to be less expensive and to push more the led against the heatsink.

LOL, I meant 1 square foot of course. I am not use to this measure but more to the square meter so it come naturally ;) Though I would love to have a big 400W cxa at 40% of efficiency in da house :fire: A meter square to power would make about 1200$ for the light then. The price really begin to...

Dude I think you should go for it. Beginning will be hard but if you fine young and motivated guys it 4years you are the new HGL ;) Look at the price of commercial panel : more than 3$/W. I would have been glad to buy a panel even a little bit higher than normal price if it is top bin led, good...

So If I understand well, Cxa 3000K driven at 1400mA provide the maximum light needed for a square meter. If used in more than 52W than not only it would be inefficient but it could also harm the plant if all the other factor are not perfect such as CO2 supplementation and quick available...

I know as a matter of fact that nutrition have an impact on the burnings. It happen to me under 250W with a too close cootube. Then I added an anti-chlorose and I didn't had anymore. But it might not be organic. and if you always gave them the same soil than light was just to intense. I think I...

Reflector are good if you grow trees I think... I like having more penetration from a light source 'cause It enable you not to put higher everyday and fuck off the LST and all this skills to keep plant low profile that takes lot of time. way too much time for me at least. Also you could fixe...

Thank You Supra, I am glad we agree that 60W/sq is not necessary and on my part I think it is a waste with no CO2 running. The driver you have from ebay are not dimmable isn't it ? 11$ shit that get the price of led under small hps (with electronic ballast)
