To add to this, the best way for CFL's to tell if they are burning the plant is to put your hand between the light and the plant. If it's substantially hot, chances are the plant is warm.

and with such a low temperature in the room, the only reason to worry about burning the plants is if the humidity is INSANELY low.

Most people iv talked to who grow with CFL's recommend many small lights.
This has the advantage of more light spread and penetration and is SUBSTANTIALLY cheaper as lower powered CFLs are more commercially available. it works for me.

But addressing the OP's original question I have heard wisps and rumours that a temperature difference of around 10 degrees (celcius, sorry im irish) is desirable as this is what the plants are exposed to in nature, but i haven't really seen any evidence to back it up.. plan to test the theory out on my next grow.

looking forward to the pics aswell :)

sorry, didnt make myself clear, my bad.
I meant maybe use more 6500k for veg then 2700k.
I like to mix up my lights aswell but i have found my plants do better during veg with more 6500k then 2700k.

What you thought i meant is 'topping'.
Out of interest do you plan to top, fim, lst or hst at all?

i dont think i plan to do any fim'ing or lst might try topping perhaps undecided tho. i got 5 feet of grow room so maybe ill leave one plant and top the other see the difference on the yield from each plant..;-)

one thing to remember is that from what iv read you can expect a sativa to double in size during flowering and an indica to double or More during flowering. not positive on this as on my last (and first) grow i LST and didnt pay much attention to the growth so cant confirm it.

my plants took very very well to topping. most of my plants are two headed beasts after ;P

you should get some good growth with the amount of light your using. what nuts if any are you planning to use?
