OMG this is awesome i love it, and that systemn you made to protect the bulbs, so clever, is it DIY or you can buy something like that?... About what twisted drifter says, do you think you've gottn your top yield that way? It looks pretty cool tho, good performance can't be denied xD
Those are commercially available cool tubes. You can buy them on Amazon and they are there more to pull heat than to protect the bulbs.
Indoors this is how I have gotten my best yield. There are five plants in there. In Illinois we are only allowed five plants taller than five inches. So that's what I grew. I do indoor grows in the winter and use the heat generated by the bulbs to supplement the house's heat. In the summer, I now grow in my hoop house. In the hoop house lis where I have gotten my largest yields ever. You just can't beat the sun when it comes to growing bud.
Back to the indoor stuff-
That picture is from my flower room it's 4x8 and I grow on organic soil. I have used synthetic nutrients in the past, I have also done different types of hydro too. I just find I get better results with less pains in the butt with full organic growing. And like I said before I have grown horizontal using scrogs and got tired of getting sore knees so I just grow up the wall on a trellisthats attached to the plants container. It's just easier to see everything and work with the plants that way.
Glad you made through covid.
Good luck friend!
