in my 4x4 tent for 3 og kush autos. They’re only in their second week. I have it at 24”, but now I’m wondering if it’s going to be enough light for them through flower. Is this light powerful enough for 3 plants in a 4x4 tent? I’m trying to keep my cost down, just bought a better dehumidifier. I’m worried that it’s not going to be enough light. I’m hoping it’s going to be enough, I’m tired of telling my wife I need to buy more equipment.

Thank you
