I haven't had any success, so what I am doing isn't really working. Indos require humidity year round, I never keep mine "dry". That being said in the past at first I tried the no brumation approach, kept feeding and lights on 12 on 12 of year round, my male still produced plugs but the female wasn't having it. Second season I cut the light cycle from 12 hours to 9 hours and dialed down the temps and cut feeding in half to once a week, with a bump in humidity (never made the soil muddy, just damp). My male again produced plugs, but the female still wasn't having it. This season I am going to do a full brumation no lights in the cage (ambient through the windows), humidity high, fresh water, no food. I am still experimenting myself so nothing I am saying is proven or set in stone, this is just what I have gathered from reading and doing my own research.
