I recently got an indoor ficus bonsai and it's doing well. I bought a grow light for it and I put it on a timer, but I'm not sure what the best light timing is for the plant. I'm having trouble finding the yearly growth cycles for a ficus and what they expect so I'm kind of winging the light timing. Right now I have it on for 8.5 hours a day to mimic more of a winter lighting. I was planning on slowly increasing it to 12-13 hours a day over the course of the spring into summer then back down in the winter to 8-8.5 hours. Does this make sense for the tropical plant or am I giving it too little light right now? Does a ficus have a winter dormancy or some sort of winter lull where it doesn't grow as much? If so how do I replicate it? In the summer and spring how much light should I be giving it?
The light I'm using is a 26 W full spectrum light bulb if that helps. Thanks for any help.
