Jollybud's Greenhouse

For the first time I had issues with night time temps in the green house and set up my heater. I connected the exhaust too a bluebird humidity controller and the heater to a temperature controller. Several days in my my circuit breaker tripped when the heater and exhaust were both on and my lights cycled. I turned my lighting down too 75% until I can insulate the greenhouse better next week. I already purchased two greenhouse airlocks to prevent cold air from flooding in through the cracks in the doors. I had to leave town for three days and the day before I left My plants started wilting. Checked my soil and it was soaking. I switched my water timer to water every 3 days for 1 hour an hour after the lights turn on. Overall these plants are adapting from vegging indoors to being in a greenhouse very well but they are definitely delayed. I see some pistil formation but no buds too speak off. Their sister plants that are still being grown indoors off site are much further along. Pics are from earlier in the week before I had issues.
