I'm happy with my setup.
It's not that big, but it keeps me busy about 3 to 6 hours a week.
I have a perpetual grow, where I harvest a quarter pound every 2 weeks.
I've thought about going larger. But, I'm happy with only spending 3 to 6 hours a week in my grow room. Plus, my electric bill is'nt that bad.
Also, I'm tired of working on my grow room. I got it to where all I have to do is maintenance.
I'm in my grow room about 20 minutes in the morning and evening, and about 2 hours on the weekend.
I'm happy with a quarter pound every 2 weeks. It keeps my grow fully paid for, with a little bit of cushion.
