If I did it again I’d go with least 8” on a 4x4 and bigger. I feel my 6” is just enough in the my 4x4or5x5 the 6” work awesome in my 3x3
How many watts do you run in the 4x4? I'll have 15sq ft, but only planning the lights designed for 8 sq ft(300w), so hopefully not too much heat to get rid of.
I could shift the budget around to make room for an 8" fan though. Ditch the 2'x4' Grassroots fabric bed in lieu of an amazon one for $60 less. That would leave wiggle room if I wanted to upgrade to more lights later too... Or just save up a little longer and increase the budget...
Though depending on what the mechanic says about my wheels, it may be next year before I'm growing again.
