A simple clip on stand to hold an LED light tube above my seeds
Not the most stable but good enough for what I needed…
Prototype was printed in PLA but recommend something more UV resistant given the grow lamps are often UV heavy
I used it with these tubes: https://www.amazon.com/gp/product/B086BWPBHL
Near identical tubes seem to be sold under numerous different brands, lengths, and spectra.
