Hi..did you ever find the time to try those blue cob? I'm really curious about that ise as alternative to uvb tubes to increase THC...hoping my bad eng question is understable. Regards!

Hi, unfortunately bridgelux from digikay has a min 200 pcs order. So I'd think to go with samsung...making some reserch i found that....do I missing something? Bridgelux is both more efficient and cheaper (run at max 700ma?)

I agree with you, it's unusual. I ve just looked at the MMG site and it seems that they removed this description (and they even removed the reference to the lack of stability ... will they really have managed to make it more stable or just remove it?!). I had read your diary about dinamed...

Hi Phenomenal, yes, you are right, the sativa dominant strain should e more a 20:1 strain but from the same seedbank you can find the "nightimele" where that's inverted, according with the seedbank description. " Nightingale (NN-1), named after Florence Nightingale the founder of modern...

Thank you ery much, really exhaustive answer..now ve cleared(a bit)my mind. I'll definitely go for CC driver. I can't understand why you (and MW as well) say that possible voltage range is 50%-100% when for the example in my HLG-240H-C1400B i can dimm it from 10% to 100%(with a really poor...

Sorry again, you' re a really kind and patient person and i do not want to impose on that. I was convinced that these bridgelux strips were 12V each, this is the reason of my question that made confusion. I'm not an electronics expert, absolutely agree but as I told you I already built my...

I again...could you reasn that? I remembar about COB wire in parallel that was a throuble because of Imax if one cob fails so i wire mine in series ( HLG-185H-C1400B) In the case stripes other people here told me that i can wire in both options or a mix bitween series and paralell and as you...

Hi could you explain it betetr, i know it's an old post but I'm just curious. Of course you're speaking about a CV driver, sin't it? i miss this part " Then keep it like that and connect 2nd cob. Verify current is 2.1+2.1. Use the other current control internal potentiometer to adjust current to...

Hi again. actually veg area is still a DIY project but i think something really tiny like a 65x50x25 cm( 25.6x 19.7x9.8 inches) just to keep a couple of "elite" clones. Maybe just ish 28W would be enought,I do not remembar driver efficiency at ish 33% , if good enought could be a nice to have...

Wow! Great answer, really helpful. I have change my mind and decide to make only a veg/mother panel and then use my 250w cob citi 1212 3500k 90cri for flow. So a small panel, with just ish 70- 80W max ..In that case the extra cost of samsung would be not so great, but i'll see... is it valid...

Hi, sorry, could somebody help me with those questions?

thanx but again : 1)why do not adopt samsung instead of bridgelux habing a better efficiency?" 2)what kind of ratio CCT for a full cycle? 3)and finally, I promise: why do not adopt a cheaper 12V 120W led driver like that...

Randomblame and Serva, thankyou so much for your kind answer. So why do not adopt samsung instead of bridgelux habing a better efficiency? I alreadh knew that with HLG-60H-20A I'd have to wire all the strips in parallel just asked you if there is any more efficient and if there are not any...

Hi, I ' d need to delete this https://www.rollitup.org/t/eb-series-gen-2-build.954608/page-4#post-13986372 I've post it in the right place. Regards

Hello, I'd like to make a DIY microgrow cab. BXEB-L0280Z-35E1000-C-B3 And here five questions, hoping in a your answer. 1)i do not understand if i must use an heatsink like i did with my COBs or if it just depend from courrent amount i will adopt (in that project not more than 35W) On...

Thanx for your answer! will all leaves get yellow or just those under spot light? And what about if my COBs photones will be not so much to cause bleaching even in case of hot spots? I' ve an hotspot with my five 1212 mount as a 50cm "cross" without reflector and so hotspot at least in...

Hi. Pardon for my banal question but why, in your opinion, hot spot may be negative....some bud will get more photones than others but no light actually would be waste..isn t it? Maybe it could affect ripen/size ?

Sorry if my answer is coming with almost 2 years of delay. So are there any solid conclusion about 24/24 lightening...any difference between auto and regular plants? I know that this was not a scientific experiment but there are also a lot of theorical aspect in support of this. For example...

something like that ? http://medicalmarijuanagrowing.blogspot.it/2013/02/uvb-uva-lighting-study-results.html there's an old but better done scientific study with similar conclusions...

Really interesting 3d...THANX!!
