wet plants this morning..wtf?

Since this is my first post, I'd like to say a big thanks to the fine folks that run this site for such an amazing resource... and to all you contributers!

I had something strange this morning when I checked on my girls...they were all drippy wet. I moved them into my new "finishing room" yesterday. It's a 2' x 2' by 4' tall compartment with a 150 HPS light. At the moment it has very limited ventilation, I'm working on that. During the day I crack open the door and have a fan blowing in air as well as a small fan in the box blowing on the light. so far I'm having no problem keeping the temp and a nice 78 degrees. I did water them all before I put them in there to bask in the nice new light from the "Flowering room" of all CFL's.

I also noticed that some of the red coloring had gone out of some of the buds. My girls are a little over 5 weeks old and flowering nicely.

This is the first time I have seen this, it's almost as if it rained lightly on them. not enough to make the floor wet, but the leaves had enough drops on them that when I stuck my hand through the mass it came out wet.

Mold is of course my fear, but I can solve that by letting things dry out good today and I'll leave the door cracked open until I finish the ventilation system.

I'm guessing since it is a fairly well sealed box that the humidity must have gone way up last night and it cooled down to under 60 degrees in there.

Is this normal? I had no idea that these plants could produce that much moisture and have I done any damage to my girls, they seem happy..just damp.

Thanks for any input in advance.

I once read that using C02 causes plants to do this

Thanks for the reply...I'm not using CO2 though.

I am begining to think that the box was sealed well enough and there was enough plants in there that they may have been suffocating themselves...not sure.

sounds like a humidity issue to me. when your room cooled off, the water in the air condensed. you need to get your ventilation up to par, otherwise you risk mold or bud rot.

If your room is quite sealed then yes, it could be humidity. you just watered and i presume its in a smaller room too. give it a day, see what happens.

Thanks for the replys.

Yes, I think that is the answer...humidity, small space and freshly watered with no air movement. Plus the temp dropped almost 30 degrees, that would definitely be a perfect set up for condensation to form.

I guess I'll just think of it as "morning dew" and leave a small fan running in there tonight and not close the door all the way.

The girls are pretty happy right now, I moved them around and have a lot of air circulation going. The color is even coming back to the big nugget at the top of Miss Trio and Shirley Temple. I named all my plants before they showed signs of sex, worked pretty good...only had 2 boys out of 10 seeds I sprouted.

I'm having humidty issues for sure. It's been foggy outside the last few days and last night the humidity in my finishing room was at 95% and 61 degrees. During the day it gets up to almost 80 and 45 to 50% RH.
So far no sign of mold, pests, nute problems or anything negative...just happy girls.
I have great air circulation now by day, fresh air in, hot air out. But at night every thing is off. I'll wire up a small fan today to run all night to see if that knocks down the humidity tonight.

My question is: What effect is this going to have on my plants? I'm about 2 or 3 weeks from harvest.

ideally you want around 40-50% humidity during flowering. anything higher than that for an extended period of time and you risk bud rot. i would definitely continue moving air when your lights are off in order to prevent this.

Thanks for the reply. I ran a small computer fan last night and the humidity stayed under 60%. I think it's going to be a challenge to control the humidity up here in the PNW, it goes up to 95%+ every night outside and on those foggy days it stays there unless the sun burns it off.
