    Which would produce more DO in a DWC?

    Real nice setup. Kudos. Now build your self some LED rigs, and do away with the hps.

    I have a difficult time swapping dwc buckets and untangling airstone tubes from roots

    Why not have your air stone connected permanently to a 2-3ft segment of air hose then use a 2way connector to attach this to another hose that leads to the pump. This way you can disconnect your hose before (with two) hand then use one hand to lift the plant and the other to pull out the air...

    Auto Airpot Waterfarm LED Grow

    Man did August fly by! Dam, I'm getting old... Anyways, here's some pics of the plants, Motherdear & #2: Not sure what's going on with #2, its been having a rough time. All the lower leaves have been yellowing up and falling off. It might be root bound? Top growth is slower than normal also...

    Anyone have anything that can beat this $749 - (12) Zero29 rig versus HPS?

    My setup: https://www.rollitup.org/t/watercooled-smart-ic-cob-led-build.943904/ for $800, you could build a 2000+ W setup, with a tad less efficiency, superior heat management and comparable light distribution. I'm just saying...:fire:

    Watercooled Smart IC COB LED Build

    Wanted to update this thread for posterity's sake. Going with the most economical means of production has its downside. Given the humidity range of 40-80%, my $1 clipboard has started to bend slightly up from the corners where the eyebolts are located. The weight of the setup plus the humidity...

    Opinions needed for this LED true 500watt $230.00

    Never buy any light that is cooled passively! Your tent will not be able to handle 500W or even 300W of pure electrically covered heat without large vent fans. These are made for street lamps applications, not grow tents. In the open mounted high up you don't notice the heat and the cool night...

    Is this a fungus or root growth

    I've been trying to clone an intact, uncut branch by wrapping a wet cloth around the stem and sealing everything with foil. It's been a week so I undid the wet wrapped branch to find what looks like a root stud? But it also looks like those fungus you find living off a tree stump. Anyway, I...

    Auto Airpot Waterfarm LED Grow

    Time for an update! Things are getting out of control, literally girls gone wild! Mother-dear is getting huge and #2 is following behind; had to defoliated mother-dear. My new light is really allowing these plants to grow like no other. I've only been running it at 100W too. Won't be maxing out...

    Issues With Ph and Maintaining Ph In DWC (Using AN ph perfect) HELP!

    I had the same setup and exact same problem. Except I was using growstones, which are loaded with calcium carbonate, and a waterfarm setup. Tap water with nutes was hitting 8 within hours. Subsequently, I'm forced to hand water my airport with 4.5 pH'd water and let the run off sit in a water...

    Issues With Ph and Maintaining Ph In DWC (Using AN ph perfect) HELP!

    Do you have any pics of your setup? Here's a suggestion. You'll need two buckets or something to hold enough water and your plant bucket. Flush your medium really good again with pH'd water. And hand water you plant until the roots poke out the bottom. Try not to let the hydroton sit in the...

    I copied the term linear intergrator from the video posted by DiodeGoneWild. To date he is the only expert on these things, so whatever he had to say, I will back up... Watch his video for more information about these linear driver chips, I linked it on page 1. BP5132H chips are termed "smart"...

    Watercooled Smart IC COB LED Build

    I'd err on the safe side and meet in the middle. If you're after cost cutting, buy a 240mm radiator and use cheap fans. Wired up two of these fans to exhaust the tent, and they kick ass. I forgot to mention the fans do not come with mounting screws. So you'll need 4 - 10mm m3 screws to mount per...

    Watercooled Smart IC COB LED Build

    The max power each chip will dissipate is 1W and the linear integrator chips have to reach somewhere around 130C? for them to begin thermoregulating the current. My guess is each chip at max power burns much less than one watt when properly cooled. The data sheet says: "The maximum power...

    Watercooled Smart IC COB LED Build

    :wall::wall::wall:Are you serious? DC regulators and SMPS are not the same thing. Step up/down converters operate off DC power; of course they will not need a transformer! Why is your device running off solar cells? because it needs a source of DC power. Try connecting your little toy to the...

    Here's a link for the Full Spectrum IC COB And the Cool White / Warm White COB Full Spec run for $3, and the others run for $1.50. CHEAP! They're from the seller I mentioned in my first post. She's very professional and ships everything combine very fast. Other people have them too, so as long...

    Watercooled Smart IC COB LED Build

    It's nothing to be alarmed about. Fluorescent, and HPS/MH do the same thing. And by jove, HPS lights are top notch... lol To the naked eye, and plants, the flicker is imperceptible. Because these lights are powered directly off the main power line they have a 60hz flicker. Cameras operate at...

    Using a phone charger as LED power supply?

    Your phone charger will work. Any AC/DC power adapter rated at 12V and higher than 10A will work. Just cut the end barrel to expose the red and black power leads and attach your LED contacts to them with solder, or however you're suppose to do it. Your LED strip and COBs are completely...
