I got tired of constantly having to adjust my y-adapters daily, as they would love to wiggle out of alignment throughout the day. My makeshift, Reflectix reflector wasn't cutting it for me so I built another one today. I bought some thick, stock cards and foil tape.
Supplies:
Foil tape, boxing tape, stock cards, razor blade, zip ties, y-adapters, Cfls, ring links.
Dimensions:
20.5"Lx14"Wx4"H
There is no reinforcing/bridging components; it's wings' angles are kept by tension created with the two types of tape.
I'm so much happier with this new wing reflector. I'm able to focus more of that light on my plants that had been escaping into my ceiling area with that piece of shit reflector I had.
