These plants have been in veg phase for roughly 6 weeks. Should I switch to 12/12 soon or let them get bigger? I'm using multiple CFL's with a grow space roughly 4'x4' with 7' vertical. The plants are between 9 1/2" tall to 11 1/2" tall. They are in 3 gallon pots. First timer. Also let me know if this setup looks appropriate. Thanks guys.
