growing in shed

Currently growing in a wood tough shed. I have sealed everything that i want to so I can control what and where the air comes in. the shed is is 12' from door to back wall. and 8' from side wall to side wall. it has a pointed rood that is 10' tall. I have two 600s and a 400 watt mh/hps digital setup in there. using twelve 5 gallon buckets with fox farm soil. I am using a 8" 450cfm fan to extract air from the grow room to through the lights and out of the shed. for intake I have a 4" hole with a 4" elbow on the inside of the shed with a cone filter on it.


THE ISSUE. I have to pull air from outside being as this is a shed. not a room in my house. this is fine in the summer when its 80+ degrees out. its when it starts raining and the outside humidity skyrockets. I don't feel I am getting enough fresh air coming into my room and I would like to make a bigger intake for the room. but I cant have the room pulling in even more high humidity. is there a way around this? I know I can get a dehumidifier. I just don't think that is practical and I feel like it will be full all the time. last year when it was raining, my gauge said that the shed was up to 90% humidity. (mostly with lights off) during lights on it was still anywhere from 50-70. (not good for flowering as far as I know.)

I don't NEED to have the whole shed setup. if anyone thinks it would benefit, I can section off and seal the back half of the shed to use for growing.

sorry for the long post, I just didn't want to leave any details out. any ideas please help. I have 2 weeks before I flip my lights and its going to start raining very soon

I had to have a dehumidifier in a former shed grow - was way too humid without it. Most rolling dehumdifiers have a place to connect a drain hose....you can get a length of vinyl tubing and a hose clamp at your local harware store. Drill a hole thru the shed in an inconspicuous spot then run the hose outside.

most dehumidifiers can be used to drain to waste, not to a bucket. I think this will be your best option. The other option would be to use a AC unit instead of in taking humid air.

I've used damp rid and calcium chloride to drop the RH in a shed grow. I run into the same problems when its raining outside and I have to intake air. I'm experimenting with peltier style dehumidifiers, to keep the RH low..
