I put up a harbor freight green house in October. I've been sealing the panels with a silicon caulk. We've got a lot of rain here lately and now all the caulking is turning to a loose putty. The caulking had previously dried.
Now the trouble is not only the seal but my panels have started blowing off because the caulking isn't holding them on.
It's the smaller of the HF greenhouses so I can't really screw in the panels on the roof. The vertical panels are screwed in.
Any ideas? Thanks!
