Undercurrent system?

Never thought of this. That’s a good idea. Jus t nought a new hood kit so I may just swap it out

Well got a little update

Have the new ballast up and running with the system all dialed in! Don’t judge on the fan, it’s going to be hung upside down.

What’s the humidity level inside the shed from all of that circulating water? Where I live, ambient humidity is often at 15-19% and i run a homemade swamp cooler (soil grow) to keep humidity up. I’m also trying to figure a way to heat and cool the water depending on the time of year. Any ideas?
