Put a line of cotton around the plants this will easy to break but not be seen easy.If the plants had been found by any person and there ready the lot would have gone bro.I would go on the basis that some animal is high has fuck now and then.I always put a line of realy thick fishing line the clear stuff not braid mono fillamont this will scare any animals that walk into it i have seen this with my own eyes.I have a outdoor grow every year and one year bits were going missing so i watched from a tree only to see deer feeding on the plants.A farmer told me about the fishing line trick it scares them because they can't suss what is going on.But always lollypop the plants above rabbit height these can also be a pest.And always never ever have all your eggs in one basket or if someone gets one grow your left with nothing.3 off my 4 have been robbed this year but don't let this get to you sometimes shit happens.
