problem in my grow room help please

howdy people il give yo the run down i have four nice plants going in a scrog style system they seem to be doing pretty well they all look healthy but ive noticed after my babies have had there sleep and i switch the light ON theres water all over my roof and bits on my walls does anyone know how this happens and how to stop it from happening??

thanks for your time.

How high is you humidity? Whats your temps High/Low? I think it condisation do to high RH or Large Temp Swings. Just a Guess!

ive been having cold nights. dosent go lower then 15 and as high and 30 (sometimes) my humidity has been real high because of the water on the roof about 85 to 90% but after i clean the water it drops to normal. i was thinking not enough air flow in the room and other suggestions???

You need to have your air intake / exhaust on all night.

i have it blowing air out of my room every hour for 15 minutes 24/7 u think that should be enough to keep my humidity normal??

thanks for yo reply.

?????????????

keep your fan on tonight see if there is a change
have you checked ur feed line for a pin prick(just a thought)
what stage are in eg veg or flower

i run my exhaust 24 hours a day and run a humidifier when lights are off during the flowering stage.

The only thing I have set to a timer is my light. Fans and everything else are on 24/7. Gotta get it under control or you're looking at moldy buds.

wow exhaust on for 24/7 thats abit full on

i run mine 24/7 too

i wouldnt run anything but 24/7 on my air. sounds like high humidity hittin a dewpoint when it cools at night...maybe run your a/c-heat or whatever your using in your house a little more? they are both designed to remove humidity.

thats too big of a temp range in 24 hours. You dont want the temps fluctuating that much. Also I'd run your exhaust 24/7 as well. The temp swings ALSO promotes molds just like the humidity, so I'd be careful. If you're looking at any decent amount of pot off those girls, a 100 watt fan running 24/7 is really no big expense in electricity.

ok so if my exhaust fan is on blowing air out 24/7 how will fresh air come in to replace the air that the exhaust fan blew out??? and another question ive been having cold nights here and my babies get to a minimum of 14 degrees sometimes at night time just wondering what this cold weather will have any affect on my plants that i just flipped to 12/12 a few days ago???

Thanks for your help.

it will come in through your intake. if you dont have an intake that is your problem. your exhaust isnt doing anything.

no really tell me you have a in take
even passive will work
