This is as close I have gotten to finding a screw in infrared light. I am working on a similar setup to yours for a 2x4
ABI LED Light Bulb for Red Light Therapy, 660nm Deep Red and 850nm Near Infrared Combo, 24W Class
Amazon product ASIN B07SGZBTLW
Nice find, thanks for posting it. Are you going to try a couple?
I have been digging around on the business of red and far red, and am not going to bother for this grow.
I think I will try some UVB though. It seems to cause buds to produce more THC and I assume likely other cannabinoids as well. It is possible that what we chase with this plant is largely the plant's sunscreen.
I think you will find the screw ins pretty effective. If you do a journal, please tag me, I'd like to follow how they work for you. Definitely give me a shout if you are able to get a quantum meter under your setup.
Also, give me a shout any time if I can help you figure anything out about your new setup.
For now I will make one observation that you can think about. One thing that I have found about my setup is that it is a
huge advantage that the doors and sides are made out of plywood thick enough to hold a wood screw. Being able to securely attach stuff like fans, filters, shelves, timers, other electric stuff, etc. to the cabinet walls and ceiling has proven to be extremely handy. If you are on the fence about whether to go with a hard side cabinet or something more like a tent, I recommend going hard side. It can still be made with a modular design that can be disassembled for storage if you want to. You could also design it to permit expansion to a 4x4 without too much trouble, something that I have been thinking about.
Good luck with it, and have fun.
