I think a couple folks on here have an HLG 260 Rspec FR
...any thoughts on whether lights like this that are meant for flowering, due to (I assume) spectrum; should not be used on autos from seed or introduced to seedlings and plants in early veg due to triggering flowering early or other unintentional effects? Anyone experienced first-hand issues with lights like this?
