First off its not a 150 watt cfl its a 32 watt cfl which is said to be equivilent to a 150 watt regular bulb.With cfls you will need about 6-10 per plant to do anything which money wise is more exspensive then a 400 watt hps setup and that many bulbs makes a good fire hazard.You can try to grow a plant with 3 bulbs but it ll cost more then just buying a sac would .Good luck
