Help a mother out...

Hey everyone, I have a rather small grow room about 6x7x4.5(height). Right now I have 6 AK-47's under a 600 watt hps. I am in week 2 of flowering and everything is great.

However the two mothers that I have in my veg partition (about 2.5 wide x 4 long x 4.5 high) are growing really slow. They are under a 4 foot 2 lamp t8 with the daylight bulbs that are 35 watts a piece. The light is just above the tops of the plants. I think they just need more light, but what can I use for a small space like that? Would a 150 watt MH do the trick?

Any suggestions greatly appreciated! Thanks

i would keep the florescents for vegging clones, as you can fit allot under the 4 foot tube, and yes 150 watt mh would be great for 2 mothers, or you can also go with cfls!
