    Big COB Setup: the annoying question.

    Hi there! Few months later (wooops, actually about a year later!) here I am with some updates. I wanted to thank all the users here for their suggestion. We started looking to quantum boards and... ended up designing one :D which gave us pretty nice results! We showed the to some friends of...

    Big COB Setup: the annoying question.

    Hi RocketSoul, obviously those heights are possible in an outdoor environment. Indoor plants will be smaller, according to veg period (but we might decide to jump it, or keep it very short, such as 1-2 weeks) and strains (Finola is very short, and autoflowering, other photodependant strains are...

    Big COB Setup: the annoying question.

    Hi Nachoo, thanks for your input. What I'm thinking about is the absence of lensens on top of these quantum boards. Does the light penetrate the lower levels of the plants? We're going to (aka we're forced to) use strains that grow even 3-4-5 meters tall, might this be an issue? That's the...

    Big COB Setup: the annoying question.

    We've found a producer in China that uses the same components of top level kits (wago blocks, premium potentiometers, meanwell, plug&play connectors on PCB) and another one that claims can customize the spectrum on a single board (f.eg. mixing some 2700K's with other 6500K's). I've read many...

    Big COB Setup: the annoying question.

    We're really excited about Quantum Boards, thank you all for the advice :) We're considering several manufacturer in China for now, and one in EU. Given the lower price point at the manufacturer level, we're thinking even to 'pimp' our greenhouses a little ^_^

    Big COB Setup: the annoying question.

    Hi Rocket Soul, I've been digging deeper in the Quantum Board world. I think we're going to use them as they provide the best cost/performance ratio. I'm wondering how much area can cover a single 288pcs LM561C panel. We were thinking to use 4*200W COB KITS to cover around 1.5 * 1.5 meters (so...

    Big COB Setup: the annoying question.

    That's correct, but those numbers are based on Citizen's datasheet, which seems to be slightly conservative (reading different threads on several forums). That may explain why the PPFD gap (measured by some user, I have to serach for the link again) is narrower. Unfortunaly there's no...

    Big COB Setup: the annoying question.

    Thanks NoWaistedSpace! We didn't think much about the Vero29's as the price difference is not that huge. (unfortunately) One of our group is a cree big fan, so only a big money saving would be able to change his mind :)
