What temperature can Vancouver Island outdoor handle?

Scenario: Plants are expected to finish 2nd wk of october and one the end of october. They dont get rained on, they are defoliated properly for an efficient air flow, decent amount of light, humidity 50-60%, watered when needed. Healthy nutrient supply. What temperature should be the killer? Thanks

Same temperature plants anywhere else on Earth can handle...

If they freeze, you're fucked. Generally you want them to stay above 40F/5C as a minimum, to avoid frost burn issues.

Okay great thankyou, ive looked at the past 5 years temps and havent been lower than that 99% of time late october so im hopefull!!

Humidity is your friend at night because if it's low, the air temperature will easily drop below freezing. Dew point is that temperature where RH reaches 100% and it becomes more difficult for temperature to fall.
