I put 24 sprout plants out last night ready to take to the plot this morning; This moring I had 24 pots of nothing and 8 snails hiding under the trays. I didn't go to the plot but the snails now reside in another dimension! Those sprouts have taken months to get to the planting out stage. What a waste of time having a greenhouse, I may as well have just gone and bought the plants! Shish!
