GrowCNanswered grow question 3 years ago How large is your tent? Do you need more power than your HLG light?
I would want to run only the HLG since the light won't be even and I wouldn't want to be the plant under the burple. Plus, I hate the way burple lights make the plants look. White light makes it so much easier to asses the plant's health and spot problems early.

I run two HLG 260 Rspec in my 1m x 1m tent.
