f I start marijuana plants outdoors in the early spring, will they have a higher mortality rate than plants started later?
Yes. Marijuana plants that have been started in early spring are considerably more susceptible to the forces of nature than those that have been started later. The plants are more prone to attacks from hungry insects and pests because there probably aren’t many other sources of food in the area. Spring weather is also notably fickle and can end up damaging young plants. It’s possible for them to be drowned and washed away in heavy rain, and also harmed by the potentially cold weather.
