You can, but yield won’t be the best. You want 2700k to 3500k for flowering


#4

How big of a yield you think?
@HornHead


#5

Too many variables. Like size of pot? Coco or soil or hydroponic? Nutrients? Lights?


#6

@Camblam light will be the single most determining factor for yields. CFL won’t yield much, but it will produce a little if you want to keep growing with it.

You can actually get good yields with warm white CFL, but you need a LOT of them. 50 watts per square foot, so a 3 x 3 tent needs about 20 of the 23 watt type. They also need a good white reflector above them and the walls need to be reflective as well. CFLs have a limited number of times they will cycle on and off, so this works best with autos and a 24/0 light cycle.

Can you mix mh bulbs and cfl bulbs? @HornHead @dbrn32

If by mix you mean have them in your grow space at the same time, then yes. But you can’t just interchange them in the same base.
