CFL Rubbermaid Grow

The Rubbermaid grow is the most practical for my situation, however I need a few pointers along the way. Currently they are 1 week in and in relatively small pots, how soon should I transplant, and to what size? I am going to be doing LST also, would it be pointless to start LST while they're in such small pots?. Because I have such limited space, there is only room for (2) 1.5 gal pots, will these be large enough to sustain 2 plants? I'm looking for the smallest pot sizes I can get away with...


Also, currently only (4) of (6) 23w CFL's are going during veg, I imagine 6 would be ideal but it creates a great amount of heat. Would it be in my best interest to add another fan, and if so, where exactly?

Thanks for any input, help and advice.

I would add a fan below to bring more co2 in at base of the plants

I'll definitely add a fan before all 6 lights are going. As for the pots, are they too small for me to begin LST?
