How about t-5's? They are a little more expensive, but you can mix up red/blue and keep them really close to the plant. You would see a better yield than the cfls, and probably than the 150w, if you set them up properly. I'd put a 2' - 4 bulb on top and 4 strips standing vertically on the corners. Total watts = 192, but at an awesome spectrum. If you can start from clone in a good hydro system(pref aeroponic), with a 4 week veg and 8 week flower, you'd have a nice bush. With the right strain, probably 1/4 - 3/4lb. Good Luck
