Cfl's can do it.That makes perfect sense, i will more than likely take that approach. If i get these cobs though they will be in the main room. Which leaves me with a CFL to veg which is ok but not as good as cobs. I can't afford cobs for both
But be aware that 3500K cobs will do an adequate job of veg while providing good flowering. A real all rounder. The 4K is similar in use.
We all use what we have and hopefully utilize it to its best. I still have several lights I keep dragging out to supplement small corners and such.
I would love to have a 4x8. That would really be a good size to get a program off and running since all the humidity and ventilation issues are easier when you start dealing with larger spaces.
