Re: California Gold
I simply dig out some banana pups, put them in my garage, and never water them the entire winter, and let my flourescent bulb (a total of 80 watts for the entire 312 sq ft area) stay on, occassionally shutting them off for a whole day. The result is that all the leaves stay green on all of my tropicals.
Just before I bring them out, I turn on a couple of my portable flourescent shop lights that are over 125 watt each and let them bake the plants of a whole week to condition them to the outside light and by the time the forecast will be more accurate, I simply wait for one week solid no frost. I then bring them out after the frosty nights and the intense light conditioning, and let them start out in the shady areas first. This way I have minimal leaf damage. The entire winter without watering, sometimes I have grown one to two leaves more in the garage with almost constant 80 watt lights and no watering.
