[Sticky] Pictures guides to Temperature and Humidity
for warmth, an oil rad heater works well. But for cooling, more extraction or Air con, and that can be expensive
I run a humidifier and small 250W ceramic heater connected to Inkbird humidity and temperature controllers. You set the controllers to turn on/off based on whatever values you are trying to maintain. The setup works quite well - my outside-the-tent temperatures in my basement are usually about 15C, but inside the tent never drops below my set value of 18.5C (lights off). Humidity is a bit harder to maintain as the outside-the-tent humidity hovers around 25-30% (and down to ~10% during the recent cold snap), and so constantly running an extraction fan drawing that dry air inside, the humidifier is constantly on trying to maintain my 50% set-point. In more humid months tho, it works perfectly. You are able to plug your exhaust fan into the humidity controller's second outlet and only have it come on when a maximum humidity is reached as well, which is quite useful, especially for drying your harvest.
No longer use humidifier or a heater so have no need for my Inkbirds now but they did a good job when I did...also used a convection heater as they are light and can be hung from tent unlike oil fired heavy job 😉
