Pest control in a greenhouse...

We're planning our first little greenhouse, with some more "real" ones on the way within a year or two... it's hard trying to prioritize things since we don't have much cash haha. Anyhow, our main issues so far have been slugs eating our seedlings, they seem to be able to get just about anywhere... We already have LOTS of great underlayment to put down for weed control, so with that down and some gravel on top we'll have a nice floor, but to stop the slugs, I'm thinking of dusting the gravel with lime. Seems like that would solve the slug issue, and possibly some issues with bacteria/molds as well. Any reasonable reason not to do this? also any other ideas that folks can think of would be appreciated. For now this will mainly be for starting plants for our large market garden, so no need for year round protection

Many factors go into solving problems such as slugs. Think of things in space relation. Are the seedlings on the ground or on a table? Are you transplanting from trays? Is the green house Sealed? What is the green house surrounded by? Can you make the greenhouse a defensible location? Where are the slug originating from? You can track slug migration to see where they are going to. This would lead to the gaps in your defenses. Can you force the slugs to take specific routes? Can slugs cross bodies of water? Try looking at these questions to find results that will fix the problem. Have a great day

Bill Mollison Presented an odd idea to deal with slugs and snails. A very small electric fence. Low voltage low cost. Maybe run on a battery. Odd idea but fun. Have a great day
