The Spectromaster CFL Bloom 300W is suitable for the blooming stage. Fluorescent tubes can emit one color, 2100º K, for the blooming phase. They give your plants lots of usable light for the best flowering and yield.
No separate ballast is required. The lamps simply screw into a standard E40 fitting (normal grow light lampholder) and are run directly through a mains plug.
CFLs have been used successfully by growers across the globe as a complete light source for their plants. There are several benefits to using CFLs over HIDs in small or confined growing areas. Less heat output makes for easier environmental control, less power consumption, and cheaper energy bills. The bulb is your primary grow light or auxiliary to your leading grow light.
