    QUANTUM BOARD QB 288 3000K 80 CRI Vs 3000K 90 CRI Show Down

    Also, is it my imagination, or are the 90's flopping over more? It looks like the 80's are standing up straighter (because they're lighter?)

    QUANTUM BOARD QB 288 3000K 80 CRI Vs 3000K 90 CRI Show Down

    Wow those chipmakers aren't lying. The 90's sure do render colors better. Those 2 pictures look like they were taken by different cameras. As far as the bulk goes, I think droman80 said the same thing in his thread... that the 80 cri looked impressive, but after harvest the 90 cri buds ended up...

    DIY Samsung LM561C build

    I guarantee that you are full of shit. Speak for yourself and don't put (stupid) words in other people's mouths. Growmau5 has put his name on deals from several vendors that he respects and likes to support and promote. Cobkits puts a lot of time and effort into what he does for the...

    What case temps (Tc) are you folks seeing with your citizen 1212s?

    Wow, its like you read my mind. I was using the citizen tool last night to estimate a build using the gen5 1212's you have (was thinking about the epoxy as well). I got the idea from this post: https://www.rollitup.org/t/driver-selection-help.945316/#post-13668467, where Danielson999 pairs 6x...

    What case temps (Tc) are you folks seeing with your citizen 1212s?

    Cool, was wondering how they fit, they don't have a large area to mount to. If you get a chance please post a pic of the bottom with the cob mounted.

    What case temps (Tc) are you folks seeing with your citizen 1212s?

    You're blinding me with all your science. I salute you for your inquiring mind and your pioneering ways. Its people like you who used to put men on the moon, goddammit!. I hate to mention it, but there was one obvious step that was skipped at the start of your experiments. That is...

    Driver Selection help

    So do these samsungs require more than 46v ea? 5x46=230, and both the HLG specs and the ELG specs show the cc range up to 238v (the "B" versions). Cobkits tested an ELG an found it performed pretty much in line with an HLG of the same size. Maybe I'm missing something tho?

    Driver Selection help

    Those Sammy's do look pretty nice. I'd prob use the $64 ELG-240-C1050B though. I was looking at these strips a while back but the price of the Sammy seemed a bit steep. Like you say though, they pay for themselves in lower driver cost and energy savings.

    Sorry to hear what happened to you :( Hope we see you back soon. When you get around to it, did you notice any difference in finishing times? Thanks for taking the time to document this.

    Maximum yield potential

    Sounds like you're new to growing, so my answer would be... waay less than you're dreaming about :P

    Anybody tried the ELG version of Meanwells, Rather than HLG...

    Any more info on these Bobby? Do they pretty much perform like the HLG's? ie. If I'm going to run 4x cxm22 on an ELG-240-48, I'll want to get the A version?

    PH swing and water replacement question.

    I let my ph drift between 5.4-6.2, but if it gets beyond that for more than a day or so, my plants become unhappy. They quickly lose that "wet" look and feel they have when they're feeling perfect, and quickly slow down their growth. After a couple days they look droopy and soon after start to...

    I've got something that crushes all the other COBs and other lights

    No the roundtable is only for youtube growers, and I don't think Robin has ever done that. Actualy, even on here I can only remember him posting pics of veggies under the lights.
