I have a 250w MH light and a 190 cfm exhaust fan with the carbon filter.
I placed a fan in there too for air circulation and a warm humidifier because I've read having 60-80% humidity in the first few weeks is great and I took it warm because it's cooler in the basement and I don't want the room to cool down too much.
The only problem here is that I need to keep my door open when my lights are on, wich is not subtle, because it's getting to hot in there, but I should receive my intake fan next week!
The temps are 21-22 degrees (celsius) when the lights are off and 26-28.5 degrees right under the plants when they are on and 24 degrees in the rest of the room.
When the lights are off, humidity goes up between 70-80%, when they are on it's between 50-60%
