    Well N A, The Tankless Water Heater is the Bomb!

    Looks great. Btw what co2 alarm do you have? I think in most places its the law that they don't display anything til they hit 20-30ppm. The only one I've seen that measures lower is The Defender and it starts at 5ppm. https://www.trutechtools.com/DEFENDERLL6070 Edit - I guess there's some...

    Controlling lots of DC fans (active cooling)

    Did my first couple fixtures at 40w ea, but now thinking of going down to 30w. I build the fixtures around the ELG-240-36a, which I get for about 1/2 the cost of the HLG's. So 6 cobs run at about 40w, 8 run at about 30w (1 driver per fixture). These are just about the last of Bobby's gen5's...

    Controlling lots of DC fans (active cooling)

    Umm thanks but... that's a low efficiency power supply (74%). As far as the buck converter goes, maybe, although this one only handles 5A.

    Controlling lots of DC fans (active cooling)

    Got 30 Cooler Master 92mm a while back for super cheap. And about to order a bunch more of these: https://www.alibaba.com/product-detail/portable-laptop-cooler-master-775-cpu_60583509720.html?spm=a2700.7724838.2017115.360.46155250c76oXT The key is finding them with a square area to mount the...

    Controlling lots of DC fans (active cooling)

    So I've got 90 1212's so far and once I've completed all my fixtures that will obviously mean 90 small fans running. I was going to buy a Meanwell 12v power supply for them, but the general purpose ones aren't that efficient or adjustable. Anyone know of a 12v supply that will allow me to...

    Oh I'm sure everything is top notch, its obvious you give your ladies a lot of liove :) But more specifically, I was wondering if you notice any difference in smell, taste, potency, etc, between the 80 and 90 cri. Thanks

    DHP Presents Citizen Cob 1812 3500k 80CRI Vs 1812 3500k 90 CRI

    So the 90 cri gave 13% more yield even though the 80 went 1 week longer. Any thoughts on taste and potency of smoke? You had mentioned that the 80 looked a bit frostier. Thanks for the effort involved in documenting this grow for us :)

    plant ph and mag Issues after switching to cobs

    That's fine for your system. A lot of my nitrates come from my 120 gallons of fish tanks. All that water eventually ends up in my hydro system, and I have more than enough nitrates (fan leaves bigger than my face). All my Calcium comes from Calcium chloride, I've been using it for several...

    plant ph and mag Issues after switching to cobs

    This my actually be your only problem. If your buckets are too small and become crammed with roots, a lot of that mass is getting drowned, not getting enough oxygen. I grow big plants in hydro (1 per m2), I only veg for 3 weeks or so in 5g buckets as they are too small, I need to switch to...

    plant ph and mag Issues after switching to cobs

    A 2:1 Ca to Mg ratio is what I aim for and never have mag problems. Also for someone wanting to add Ca without adding a lot of N, Calcium chloride is an excellent tool to have in the arsenal. It also adds chloride, which is a micronutrient most people never think of and that a lot of gardens...

    plant ph and mag Issues after switching to cobs

    I think 85-89 degrees would be too warm, especially under his hid lights. I think he's already in a pretty ideal range for led. Edit- just reread it and I missed the mention of tents the first time. I thought these were tables next to each other. In that case I agree, maybe bring up the...

    How to maintain Beneficial bacteria in DWC?

    No, the idea that fertilizer kills microbes is a myth. They will do just fine in DWC. The thing to get into ones head though is that if you are committing to running beneficials in DWC, then the "standard wisdom" no longer applies. So no sterilizers (h2o2, bleeches, etc) and no worrying about...

    Amazon COB light, CREE CXB3590, Meanwell driver, 200w, 26000lm

    The big problem with that light is that the cobs are driven twice as hard as they should be, destroying all your efficiency. If you want a cob fixture delivering 200w, you want to use 4 cobs (in this class of cobs that is). Here's a much much better choice (newer more efficient cobs as well)...

    supplementing uv With argomax Pure UV

    HLG will soon be selling their own custom designed florescent, meant specifically to supplement white phosphor lighting. It will have UVA, UVB, and a bit more. No pictures of spectrum yet, I believe they are awaiting delivery of the prototype. I think that Stephen said he hoped it would be...

    Cobs have burnt

    Yeah you'd think the plants would die before the cobs if ambient was the issue, considering that they're tested at 80c.
