These feminized seeds flower automatically. Once germinated they will proceed to grow with a short vegetative period followed by flowering - regardless of daytime hours. In other words, even if the daylight hours are greater than 12 they will continued flowering. This makes them a great spring time plant that will finish in early summer, just about the time when you'd like to plant your full or early season crop, giving you two crops per season! Since they are a quick finishing plant and produce high density quality Hemp Flower, some farmers run them early, plant again in early summer, and are able to plant yet again in late summer, allowing them to get 3 harvests per season! This is also a great way to hedge your bets if something should happen to one of your crops, you have more on the way!
