humidity

hi folks first post so hello all,i have a problem with my humidity.i was bringing my air direct from outside but due to cold weather i,ve had to start bringing it in from inside.i bought a humidifier and put it in the room that has the fan but i,ve had to keep the heating on at night as my babies are in the loft so the air is very dry and my humidity level has been at 20-25 when the lights are on and about 25-35 when the lights are off.i know this is not that good so any help would be grateful please.thanks folks.p.s my babies are 3 wks into flower.:thumbsup:

You don't need too much higher humidity- 30-40 is fine. Keep your plants well watered and the ambient temps between 65 night and 80 day (high / low) and monitor for signs of stress from too arid conditions, which is when the edges of the leaves start to appear curled sharply upwards.

thank you.
