no probs mate, the other option would be to get a load of them cheap energy saving bulbs (cfls,) all the ones you get in super markets are perfect for the flower stage, they are all 2700k cfls, range from 11 watt upto 20 watt in supermarkets, you can usually buy them in packs of 4, these cost next to nothing to buy the brighter 6500k cfls are harder to get and more expensive but their for the veg cycle which you dont need, so you could go out and get a few of the cheaper 2700k cfls id say go for the 20watt ones or 23 watt if you can get them, ive got 30watts that where more expensive but still cheap and ive got loads of the smaller 20watt cfls to use around the plants, so if you bought some of the cfls the normal warm white ones that you use around the house then buy some light fittings that get from a hardware store and wire it up to a plug, you could wire 4 or 5 of these lights into 1 plug socket, you would need to make something to hold the sockets so a piece of wood will be ok for this and screw th light fittings to this then plug it in, this will then help the flowering process loads, you can also keep the cfls lights close to the plants to get the most from them as the light level drops the further away the bulbs are and these cfls give off very little heat so wont stress the plants.
its just an idea mate, and it wouldnt cost much to set up, its all ive done, i bought a load of light sockets for £0.79p and i secured them to a piece of an old fire guard i had cut down and i just use that above my plants in the veg room and it can hold 9 cfls ive only got 6 in though and its ok for what i need, and my flower room has got 2 30watt 2700kelvin bulbs hanging on a bracket then ill hang others around the plants ill use the 20 watt cfls to hang around the plants to ensure i get the whole plant lit up,
