Was gonna say cold , I chucked a stack of seeds in a flower bed where I use to chuck old soil when I use to grow in house and garden bat special one summer , thought fuck all ov it , few days later there was a dozen sprouts popped through , couple weeks later left the most sexist one out the lot and binned the rest , anyhow grew bout 7-8 foot tall and had to tie it down but started to flower then the colder nights kicked in so didn't produce real bud but shit load of trichomes, only experience of outdoor growing for me , and that wasn't even intended .
