you can pick up 2700k bulbs nearly everywhere, amazon ect. or many shops sell them, diy shops, supermarkets, anywhere really, just try to get as much lumen as possible per bulb, remember higher watts doesnt mean higher lumen, and you will find it is very hard to get the cfls where they need to be, if just leaving to grow you will find fan leaves get in the way and you cant get lights close enough to the main bud sites, and you end up burning or chopping leaves, all of this is unwanted stress, what i do is almost modified lst (low stress training) when i get to 5th node i gently bend and tie the stalk to one side of the pot, i usually let her need water just to make everything more flexible (i only starve her once so she can recover) once side shoots start to grow a bit i release her and let her grow towards the light as usual, when she grows vertical again, side branching is extremely slow, but i tie the side branches slowly so they grow outwards, when the mj is budding i found this extremly useful as it ables you to place the cfl inbetween the main cola and the side branch, using the whole cfl rather than one side, and remember to use the sides of the cfls not the ends as these give off more light.
