Just keep bulding your empire mate. Add things bit by bit. Bit of insulation here, new temp controller there. Humidifiers, dehumifiers etc.......
I plan on controlling a main room, pull fresh air, filtered. Then my main tent,s can either stay open or suck in air from the main room area. That should make things easier to control in each little area.
It's all dreams lol. But that's how we build our canna empires
