Well I can only speak for UK for certain from my knowledge but there would be absolutely no point even thinking about starting a photoperiod plant here now it's simply would never get going you need to start them before the sun sets in for them to actually start growing properly you could start auto flowers now in this country but it is still too late for them ideally to get the most out of them.
We have some auto flowers virtually ready for harvest right now we started them at a perfect time in the year and they have done extraordinarily well in the peak of the summer. 74 days and we will harvest three within the next week with another two 2 a week or two behind and but hopefully before we get any prolonged damp spells with luck.
