Earliest outdoor grow time in BC?

At 13c the temp is too low to get good growth. Especially on an autoflower. Once the temp drops below 15c the growth almost stops on most cannabis strains. I would really try to avoid growing outdoors until the average temp is about 20c. Autoflowers don't have much of a window for issues so slow growth during veg could really kill your yield. If you don't have a choice, and have plenty of seeds to run then go for it. Some buds are always better than no buds. Good luck!

I do 3 runs with autoflower in the year outdoors. I start first run Indoors, and take them outside or in the greenhouse in middle of My. Then I start a grow in middle of june,,, thats the perfect run most times. And then i start on August.. and end them indoors

If you grow an autoflower, you pick the best 12 Weeks in the Year to have the best PerformanceAnd autoflowers looove Light. They love warm nights and 18 Hours of light so get the best i8n middle of june outdoors with your Girls. A Photoperiod dont care so much for optimal conditions. Those you can take outside as soon there is no Freeze and above 10 Degree in the Night. I think you asked a similar Question and i give you now a similar answer

You can plant in March without any problem, but I recommend putting 1 or 2, then in April another 2, and then in June you put all of them to harvest in August. In my opinion, you can plant whenever you want, but if you want to put a lot of autoflowering ones all at once, it's best to wait until June or late April.

When you chose the place for your plant try to see how much sun it actually gets sometimes you can't reach to get all of the 12hours, I would start during first days of April..
