Did it rain inside my grow box

I just got done building a new grow cabnet yesturday. It's 30"x30"x48". I have a 400watt HPS inside it that I just got a little over a week ago. The plants have been under CFLs. I have an exhaust fan running and venting through a carbon filter into the room it is located in(works fine no smell whats so ever). The plants that are in there are on 12/12. Most are about 5 weeks into flowering. Some I just put in there to flower yesturday. Now this morning I was waiting for my timer to go on so everything would kick on(just wanted to make sure everything came on at the right time and functioned right, it did). I opened the cabnet and there was water droplets all over all of my plants. It looked like it rained inside this cabnet. I looked at the top thinking something leaked into the cabnet, but nothing. Nothing on the floor of the cabnet either. Just droplets of water all over the plants. I mean alot. It really looked like it just rained in there. Here's a picture of some of the water droplets on there still. Most have dried up so far, but I don't want it doing this every night. Temps in the cabnet are about 75-80 so far. The cabnet is located in my basment. Humidity is about 60%. I do have a dehumidifier running. I am kinda at a lose for what to do to prevent this from happening. I am now worried about bud rot if this happens all the time.

scroll to bottom of thread for info on VPD, but great info all around.

during flowering u want the humidity to be at 30-40% so u can prevent mold to your buds

Nice looking box, Maybe i dont see it but do you have a fan blowing fresh air into the box or a fan in the box just to move the air around.

Yes I do know this. I am growing in a basment in during sumer so humidity is extremly high. Thats why i have a dehumidifier running. Even if I wasn't growing I have it running. During winter it goes down to 30-40%. This isn't my first grow down here. I have been growing down here for over a year. This is the first time gorwing in an enclosed space. I was only doing 1 plant at a time so smell wasn't bad. now with growing as many as I am the smell is bad that why I built the grow cabnet so I couyld control the smell. now I have problems.

u have exhaust in that grow box?

There's an exhaust fan on the top of the box itself. That has a box built around it to make it alittle more quiet. I also have a dimmer switch on it to control the speed. As far as fresh air I have 3-3 inch holes drilled in the lower back of the box that allow fresh air into it. I wanted to keep a negitive draft in the box so no smell would get out of the box unless it went through the filter first. So I didn't add a fresh air fan to blow in.

As far as air moving around. The plant litteraly move all around like there is a fan blowing on them from air moving from the fresh air holes to the exhaust fan.

Yes l;ook at the pictures you can see a box on the top of the cabnet with a filter on the back of it. Thats the fan enclosed to keep the sound down.

but where is that exhausted air going??

Sounds good, but bud plants luv air movement. If you were to put little cooling fans(from radio shack) on those holes blowing in that would force fresh air into the box and not allow the smell to seep out.

Through the filter into the basment. There's no smell now cause of the filter. Is this a problem? I can easily vent out of the house. I just figured it would be fine to just vent into the basment through the filter as long as the smell was taken care of which it is.

a carbon filter will cure all of that smell and keep the air in your grow cab clean and not stale

doesnt matter where you exhaust it to, you need air movement

You have remembered humidity goes right down during flowering? I've never seen it that bad before, really does look like it's been raining

Huh what??? I have a carbon filter. Smell is not the problem here. The problem is I have water in the grow box from sitting during the dark period. It looks like it rained in ther box from sitting all night. Smell and heat are not a problem. I think we are getting way off track here.

Two options I see are:
Keep running the dehumidifier or get something like DampRid.
Or unseal the box and add a flow of fresh air. (That is if the air around the box is any better, if it's in your basement then it's probably not.)

im guessing it's outside lol, it's almost definitely dew, just like on your grass, its probably not completely airtight and moisture proof, so there's your dilemma

Just think I took that picture 20 minutes after the lightes where on too. So most dried up. That was just one of the many spots I seen with water still there so I snapped a picture. It was bad.

did you water recently?
