I recently bought a autocob like grow light, 55 Watts with a CREE CXB3590 spitting out somewhere around 8000 lumens.
Thinking about buying three more and using the four of them in a 1 square meter tent.
Can anybody tell me if that would be enough light to grow some autoflowers??
If you go for 5th in the middle and have an X formation you should get full coverage if your aim is wall to wall bud, scrog growing
