You can buy big cfl lights from home depot, the lights you have i think are 13watt but 60 watt equivalent.

You can buy 42 watt cfl 150watt equivalent from home depot. Also you dont actually need a red and a blue light litterally. You need to look for the the light spectrum number on the box.... It will say something like 2700k or 5800k . This number tells which part of the light spectrum your bulb is in. A bulb somewhere around 2700k is a more red dominant bulb while the 5800k is more blue dominant colour. blue for veg, and red for flower.

I would suggest that you get a couple larger cfls if you want to keep area very small or get some t8 fixtures like suggested. The t8 fixtures will be usefull to you even if your setup grows to a larger one.... For clones,cloning more seedlings. Either way it is not a bad invesment. The lights you currently have will be of no use to you very soon...... unless u eat mushrooms.
