    VPD vs "80-85°F"

    Michigan grower in an unfinished basement here too. Environment is my constant enemy. Someday I'll build an insulated room down there, with climate control galore, but for now, the struggle continues...

    VPD vs "80-85°F"

    Good topic. I'm very interested in this myself. I've definitely seen a huge leap in the health of my plants, over the life of the grow, by getting temps up over 80°F and humidity around 60%. BUT, I did have mold issues by the end of flower in my last run, and lost too much bud because of it...

    Best T5 HO conversion options? Worth considering at all?

    That's the most often suggested for flowering. In veg you don't need that much.

    Expanded on my QB 260 v2 kit

    You might also want to consider filling that empty space with some 660nm QB11s.

    Quantum boards in a 4x8

    Agreed. Only reason to get the 550 would be if you need a pre-built, or if you care about certifications. The 600 is a FAR better deal.

    supplimentry led lighting

    From that page: "Features state-of-the-art 3 watt color diodes by made by ProLight Opto of Taiwan, which meet and exceed the quality of Cree XPE monos, with better thermal management and greater resistance to humidity, all at a significant cost savings." I'm not familiar with those diodes (or...

    Best led grow light for a beginner

    Budget? And are you looking only for a plug-and-play unit, or is DIY on the table?

    5×CXB3590 3500K LED @1400mA

    Never grown it personally, but I hear White Widow is a good hot weather strain.

    Chilled logic puck?

    Not looking to start an argument, but I must disagree. At an appropriate height from the canopy, 25 COBs, at 25w each, should offer better penetration than fewer, higher-powered emitters. Granted, you would have to keep the light closer to the canopy to achieve your target PPFD, but once set at...

    DIY with Quantum Boards

    You're a crazy bastard, and I love it. As much as I appreciate the efficiency aspect of growing with LED, a gratuitous grow like yours is refreshing to see. Looking forward to the end result!

    Chilled logic puck?

    There's nothing about COBs that inherently provides better penetration. Penetration is more an effect of diffusion than intensity. Generally (and simplistically) speaking, the more points of light, the greater the diffusion, and the greater the penetration. Strips, COBs, pucks, boards, whatever...

    Setup for growing in cool temperatures

    You still feeding them the magic tomato food? Must be damn good stuff, because your plants are always rocking.

    Setup for growing in cool temperatures

    What nutes do you use, and how heavy do you feed? Seeing a few growers here who manage to do well under LED without getting their temps over 80°F, and I suspect the feeding regimen has a lot to do with it. I can tell you that growing in ROLS, if my temps drop below 80, things go to shit right...

    Cheap Chinese LED companies - the Good, the Bad and the Royal Ripoffs

    Yeah, he spent a LOT of his time here being offended by inoffensive comments. Very sensitive type, I suppose. And that made his perpetual "namaste" seem a little out of place, to be honest. Generous dude though.

    Cheap Chinese LED companies - the Good, the Bad and the Royal Ripoffs

    I don't think anyone is doubting that they'll grow well. It's more about whether or not peeps are getting what's advertised; I'm sure some are, but I'm also sure some aren't. @Prawn Connery is simply trying to establish which companies have a history of lying, and which have a reputation for...

    Cheap Chinese LED companies - the Good, the Bad and the Royal Ripoffs

    Wasn't joking. Thought maybe you meant "do your own digging", but wasn't sure. In any case, I don't see why someone should get shit for asking the people who've already "DTOD". That's one of the principal functions of community.
