Definitely will slow down growth but if its just a couple nights, not a big deal.
I think the question here was if they could handle a chilly night here and there. Yes.....they won't like it but it won't kill them.
Doesn't CK send out a tracking # when seeds are shipped? Five days should be plenty to ship across Canada.
Try True North Seeds if you want to keep it in Canada. They aren't perfect but their customer service is helpful...and kind!
Hey JJ...
I assume you have ordered heat sinks from Northern Grow Lights in the past? If so, do you happen to know if I should be expecting any extra taxes and duties with shipping to Canada?
Thanks!
Update time...
Looks like I'll be harvesting sooner than I thought. I had estimated that harvest time for the earlier two (Akorn and Purple Trainwreck) would be near the end next week...and the other two would be a week later.
I thought just for shits and giggles I would check the trichome...
