I have 1 plant using 3 cfls for flowering. They are 40w 2600 lumens each. Will this be enough? Or maybe 1 more. I was thinking about adding a T5. But I hear it's the lumens that count. So right now I have 7800 lumens for 1 plant. 1 above, 1 on each side. Don't want to buy anthing else if it is't neccessary.
