temperature control

Hi, I started auto white widow a week ago. They all sprouted. The 48x48x80 grow tent is in my bedroom and my tent temperature is always 10-15°F lower than my room I'm guessing because of the humidifier. So I knew I had to get a heater since my room is getting pretty hot just to keep the warm...

Hello there everyone, after moving to a new house I'm realizing that my grow room is holding right at 70F with the light on and I need it at 82F. I'm running my central air at 74F and refuse to go hotter than that for the rest of the house. I'm considering a space heater for about $80 on...

Growing some auto flowers, what is the optimal temperature range that they like? Also what range of humidity should I try to keep the room at?

So I bought a hygrometer Only this 1 is Bluetooth, it's around £8-12 so not too expensive, you download an app then you pair it then you have a digital display on your phone to keep track, and the party trick is that you can set it up to send you notifications if the temperature or humidity is...

Hey guys, I'm looking for people who have experience with having lights without air-cooled hoods AND without them. How big of a difference do air cooled hoods make for overall temperature of the room? Is it nominal or significant?
