http://www.lumileds.com/uploads/600/DS162-pdf Hello. What do you think about these COBs? Efficiency seems good and they cost 1/3 of vero29 and less than 1/4 of cxb3590. I don't know the spectral data of the light and do not know how they work in grow practice, They are produced by Philips ...

Hello rollitup growing community, I have just finished my first set of DIY grow lights. Its a simple setup for a 2x3 or 2x2 grow box. I am using an HLG-185H-C1400B driver, currently 2 Cree CXB3950's and some cheap but silent Alpine fans on two separate heat sinks. My driver runs at an operation...

I'm two weeks into flower with a Sour Jack grow. There is a single plant in a soil bed 2.5ftx2.5ft. It is all recycled organic living soil in its 3rd round of no till. I don't have a great schedule with my plants instead I just try to do what I can when I can. My specialty treatments are as...

I apologize if this has been posted somewhere, I have scoured this forum and the rest of the internet trying to figure out how these two pieces fit together for assembly but I can't find the answer. I found this video but they are using different reflector holders...
