Mods, please move if needed. My inherited greenhouse is a bit peculiar because the previous owner bolted a few extra and very thick glass panes onto parts of the inner frame. Hey ho but not to worry UNTIL the other day when I saw some snails had taken refuge between the two panes where I couldn't remove them, and my plug plants had a few leaves chewed. I did remove an escapee but the rest are beyond my reach. I sprinkled some organic slug pellets between the two panes of glass and on and around my plant trays (these are on the beds so I can water them properly instead of them being in my mini-g'houses) so, having had a nap yesterday afternoon, I thought - if I can't get them out then I'll keep them in. Today I plugged the gap between the two glass panes with bubble-wrap. Whaddy ya think? Will it work?
