helicopters HAD to see at least 3 of my plants last year and didn't even waste their time pulling them.I was scared as fuck when harvest came around so i just walked aroud every patch for a good half hour just looking for stuff that wasn't supposed to be there and harvested all with no probs(whith the exception of one plant that had alot of sun but still only grew to about 8 inches and gave me about 3 grams)
