Happy 420! The biggest threat to my outdoor guerilla grow is not the police or being discovered by a nosey neighbour... Its slugs! To combat this I grow the plants tall in my tent, removing side branches to get them long and lanky. Once I plant them out, I use plastic collars with copper tape as a physical barrier and slug pellets around each plant. This year I am most excited about Parvati, a charas plant from the Himalaya!
