I put a wet white towel on my grow rooms floor and a cup of water next to the plant.When the light is on moisture level is around 60-70 but at night it gets down to 40-45.Is this okey? what should I do to raise the level of moisture at night??

thanks alot.

40-45 RH lights off is fine, its fine for lights on too. In veg if it drops below about 35 it becomes an issue, In flowering 35-40% RH is best IMO.

Should be ok althou 30C is a bit too hot, You want a max of 27C. For best results 25c lights on 20C-21C lights off.
