Growing in basement closet/condensation problems on walls

Hey guys,

I have a grow going inside of my basement inside of a sealed closet, I don't have the ability to vent my exhaust elsewhere so the air is recycled unfortunately. The plants seem to be doing fine without the addition of c02, thankfully. Anyways, my issue is that I have brick walls and they seem to be sweating from the temp difference of the brick vs. the grow tent (warm around 75). Any ideas to get rid of this condensation, I don't want to be damaging my home because of a grow tent. Ideas? Thoughts?

Thanks guys

Whats your RH?

This might seem like a stupid question, but was it sweating before you started to grow? Does water leak in when it rains?

During the day inside tent my meter reads from 55-65% RH, and at night recently its been all the way up to 90% RH.

Yes, minor sweating before I started to grow. Just seems to have caused more of it to happen since I started with the grow tent.

You may have to improve your extraction some

Id get 2 badass dehumidifiers for inside and out of your tent. Humidity that high will ruin ya

I have a GE 30 pint dehum for my basement outside of the closet, but that obviously does nothing for the grow closet. Maybe I should move it into the closet...just have to empty the bucket every once and a while instead of having a hose to my sink drain like it's setup now..

poke at this https://www.icmag.com/ic/showthread.php?t=112862 its the best yet on venting

*Update*

I just opened the door to the grow with the 30 pint dehumidifier going in my basement, and that alone dropped the humidity down to 40-50 RH and completely stopped my sweating brick wall problem. I ordered a 50 pint dehumidifier specifically for the grow closet so we are in good shape now! Thanks for the help guys!
