U sure your light isn't melting snow above and going through the cracks ?
I had this issue before I started my grow. My grows in my cold cellar Now but before it was all concrete and the front porch on top of it leaked.through the tiles ..I waterproofed from the outside and used the Styrofoam insulation framed and drywalled it.. Your getting way to much moisture if its dripping..gonna cause mold fosho..try bringing in more warm air from the house..what's ur temp
well finished everything all is good so far.....2 inch foam, dehumidifier back on, good intake and exhaust. concrete ended up being 7 inches thick, soooo hard to drill even with a brand new 1/2" bit. Thanks for the tips guys!
