Sprouted at 5 days. Bought three of these from Seedsman and all 3 seeds germinated. Seed planted directly into a mixture of Fox Farms Happy Frog and Ocean Forest soils.
Kept light on all the time to keep the tent warm until the seed sprouted, then put on 18/6 schedule 6 am to 12 am at 40% of 200W intensity. Inline fan set fairly low to keep humidity and temp in the tank up. I have another small fan circulating air inside the tent.
I have an AC Infinity T3 Cloudforge humidifer in the tent keeping it at 80% RH. The display on this humidifier went out after my first grow, but it still seems to be able to be set with the controller.
I'm not sure I would go with AC Infinity in the future; I have mixed feelings about the products. The light, inline fan and oscillating fan have worked well. The controller struggles to come back sometimes on updates. I warrantied a cable that came with the humidifier once. Customer service did not seem enthusiastic to help. Because of the delay I didn't use the humidifier with the controller for the entire first grow. Now it I do not have an option as the display does not work at all. I do like being able to operate the humidifier from outside the tent. The connecting tube has to be positioned just right to not get clogged, but reading about this humidifier it does not seem like the electronics are insulated very well and I don't recommend using it inside the tent.
