you still got loads of time, i been popping 10 seeds every week since may 1st and gives me a week to find room for them. i'll probably pop another 10 photos next week as well and put them out, often the late ones do the best as they don't needs as much water and in general i find smaller plants have better terps.
I believe so mate yes not looked at them a couple years still got a few in fridge always found them reliable all round
sometimes the indica dominant ones grow short and compact but still a nice vape
