Humidity

Hello all I have a humidifier , im just wondering is it worth using it. (Its a very dry cold climate where i am) I will be using a dehumidifier for flowering and it will be very dry.Also i have a cold air mover so i am wondering should i try to put that near the 400 watt bulb.

That would help the heat on the light out. When you veg it will make a big difference. Like a warm rain forest. If not they spend alot of time and energy trying to save water from transpiration.

ok maybe i will set that humidifier up then, and try to hook up the cold air mover next to the bulb as well

Humidity for cannabis must remain between 40% and 80%. Optimal being 60&.

how can you find out the humidity level?

buy a hygrometer. Thats a thermometer and a humidity gauge combiened into one unit. $10 to $20 at target, kmart or walmart.
