The premium kelp meal improved things, but not like crazy crazy good. If you can get your hands on it give it a shot but otherwise don't feel too terrible about missing out.
Honestly the height on this thing is baller as fuck for me. But also it's a food sturdy build. Light leaks are generally to a minimum even with a velcro pane. It functions wonderfully as a flower tent, provided you have the ceiling space.
My cat loves to sit on top of it.
I might be being harsh, and I might just be expecting this thing to do what it can't, but overall not impressed with this light. The dimmer switch on it is nice, but I don't feel confident I could flower a 2x4 tent with it. It is fine as a veg light, but then again so is a blurple.
