“One Hollands Hope was male so I set it outdoors to segregate it. This plant lasted 10 weeks longer than other strains. It survived 3 consecutive nights of 18°F weather - the top and sides of the soil (left it in the pot) was frozen hard. I poured 2 gallons of very warm water over the soil at midnight each night. The soil surface was still frozen in the morning. The plant didn't mind. It thrived outside 8 more weeks, surviving a second 2 day freeze as well.”
