FINALLY, after much waiting my Habs are starting to bud and flower. I have been growing them here on my desk at work under and grow light. I also alternate them to the window sill over the weekend when I can't leave the light on. I'm all FIRED UP!
I'm using a Sun Blaster 6400K full spectrum (coil type bulb). I have found that the plants grow extremely well under the light but they do not bud. If I take them out from under the light and put them on the window sill to get them some natural sunlight, they start to bud and flower.
