Here's one for ~$14...

Yes, but shop around. I think you can find them cheaper.

Check out this thread: https://www.rollitup.org/t/grow-room-automation.929606/page-4#post-13423366 Wiring the power meter video:

You want to ping @VegasWinner . He added a power meter to his setup that cost about $9. Even made a YouTube video to show to wire it up. Pretty slick!

Jumping in late here, but isn't the point of using copper in a liquid system to quickly transfer the heat away from source (the COB) through the copper to the liquid and then from the liquid to some other heat transfer mechanism remotely (a fan and radiator )? That's the advantage of using...

You can buy it online direct from the manufacturer. I bought a 25lbs bag and it shipped to my door. ;-) http://www.jrpeters.com/who-are-you/hydroponics/shop-now.html

Jack's 3-2-1. Google it. Simple, cheap and effective! Been using it for 2 years. There are some YouTube videos on it as well. Good luck.

Thanks for helping an old man's eyes! Nice!

Hey @VegasWinner can you take a close up of the display? I can't really make out what it's displaying. Thanks.

Thanks for the video. Way cool!

Can't remember the thread but PM @VegasWinner , he has a kit you can purchase to do all the light controlling you want.

You probably purchased an "audio taper" pot and not a "linear taper" one. That's why you don't see the nice gradual dimming.

I had a similar area (4x9) and went the same layout and COB, 36 1212s. I had a custom drive built to deliver 1300mA max. After I did the math for current vs. threshold voltage I wasn't sure the meanwell 1400 drivers would do it (others have done it and have been fine ). Make sure you get...

Now that's what I am talking about! A central control box for each room, controlled by a web page or phone app that also gathers data! Damn @VegasWinner you are about a year a head of me and what I want to do!!! Can't wait to see your finished product!

No worries on root tangles.

That's why I went to a chiller and swear by it now! It doesn't seem like that will work in @Smokey57 case. Controlling the heat is always the issue.

Look fine to me. Roots get twisted with bubblers and water flow. Your water looks a little colored, so maybe its residual nutrients or something you added to the water?

Well, if you want to think outside the box, you could get some rigid foam insulation, cut hole that fit your containers, then separate the upper part of your room from the lower. Trying to use the coolness of the floor to get your buckets cool, and separating them from the warm upper air. Even...

Well, for me I had a 16 5-gal bucket RDWC setup and the $400 investment kept my buckets at 67 degrees when the room was 80! Not for everyone. I wasted money on DYI solutions before buying an off-the-shelf model. Could of saved money in the long run. My plants ❤️ it!

You really need to invest in a chiller! I did and made all the difference in the world! Warm room , cold roots, heaven for the plants. Look at Active Aqua Chillers. They sell them on Amazon. A chiller is worth the investment! Edit: sorry didn't see your last statement. Maybe this not an option...
