I run the photobio, luxx and the roi 720. With the lux I get smaller denser flowers and some strains seem to ripen a little quicker under it. The photobio looks more red than the luxx and I get larger, but more feathery bud sets. If that makes sense. Some things also seem to take forever to ripen under that light but it might have to do with the spectrum just tricking my eyes. The roi seems to be pretty harsh of the plants and even with co2 I don’t usually push them at 100%. They are also hotter for some reason and that tent almost has a yellow hue to it. The photobio is probably my favorite and I’ve got the largest yields under it, but that could have to do with other factors
