When planting outdoors is there a min. time duration that the plant needs. If I plant a plant and it gets cold in say 3 months would it be a waste of the seeds for such a short grow time

You could probably still get away with an auto or a Regular FAST seed. Better hurry though…

not sure how cold they can handle but you can put a plastic bag over them at night for a little help.

I’m sure there are a number of Auto Indica strains out there these days, he should be able find a couple that can tolerate lower than typical temps and still finish. The plastic bag thing is a good suggestion as well.

Buy some lights.

The trigger for wether they grow vegetatively(leaves & stems) is the amount of darkness they receive, not temperature like in many others.
Hours of daylight is dependent on latitude so you may be on the equator getting 11/13 or 13/11 or way up north with those 20hr summer days & early snowfall. 
They grow best at 70-80F with some humidity & slow to a crawl near freezing. Most probably can’t tolerate frost. (or rain because it rots the buds).
Auto flower types are different & will ignore the light schedule, & just flower automatically.
9+ hrs of dark = flowering for “photos or photoperiod”
So 15/9 is about as close as I can match the outside moving from indoors. I take them down 1/2 hr every 2 days & it seems to work.
No plastic bag - traps moisture

Well, he said it will be getting cold in 3 months, so I know he’s not talking about anything in my latitude down here in the southern US
I’m in ny and I’ll get until middle of October ish. Parts of ny closer th nyc and Long Island have a longer season
So you’re more upstate then?
You can plant all summer long, the earlier you plant the bigger it will be, if we’re talking photoperiods.
Here in Belgium daylight goes below 12 hours in September, so sowing/planting right now (early July) would get them roughly 2 months of vegging, which can still get you a decent bush depending on genetics, soil, sunlight, etc…
Even if you plant in September you can still get a harvest, it’ll just be less.

Plant them in a pot. Put them outside during the day and bring them in at night. You have complete control.

I’m in zone 5b, my last outdoor plants ran into October but that was pushing it with how wet our fall is.
I’m at 1 week above soil on 4 autos outside as well in 5g buckets

We’re similarly zoned. I’m seriously considering starting some autos today to finish before winter. I think timing is perfect for a second harvest (first harvest will happen possibly as early as next weekend).
