...will try to answer your questions as bes' I can:

â?¢ Should I get more lighting?

Yep. Your current lighting seems ok, but they will need more lumens before long. Think about getting a nice digital ballast, and perhaps either a MH or HPS bulb in the 250w - 600w range. 600w would be nice overkill in the space you seem to have.


â?¢ if so now or just when they get bigger?

You could augment your lighting at any time. MH will give you a great spectrum for veg, and HPS a great spectrum for flowering. If you're thinking about adding either of these, try to get a digital ballast that will drive both types of bulb, or at least one offering a manual switch to do the same.


â?¢ Will I need to transplant them again? I know the roots get big and i'm not sure if those pots will support them.

Those pots should support 'em for a bit yet, but you should transplant 'em into at least 3ga. pots when the apparent 'size' of the plant is larger than the container below it. 3 gallon pots should be enough, but if you have a particlularly vigorous one, give it 5ga.


â?¢ When is a good time to stop growth and switch to flower?

Try to veg 'em until pre-flowers show. That will also help you to determine if any are male and need to be culled. Once switching the lights to 12on/12off, you MUST not let any light disturb their sleep period. Make sure your grow area is light-tight, so as not to stress the lil' darlin's in their dreams...

Hope this helps--I'm sure you already have your PH and temperatures nailed down, of course
