Cannabis varieties Growing

While patience is a virtue when it comes to growing, you don’t have to suffer the pain of waiting. With early finish outdoor strains, you’ll get faster harvest periods for outdoor yields. This is particularly useful when you need to take advantage of short bursts of fine weather. Temperate climates, for instance, like the UK and Netherlands, benefit from quick growth through warmer spring, summer and early autumn seasons.

Late to the growing season? Then this is what you’re after. You needn’t worry about compromises when it comes to these early finish outdoor strains, either. You can pick from high-THC varieties that are packed with flavor and loaded with long-lasting effects.

What does “early finishing” mean?

Early finish strains are exactly as they sound. These strains finish growing earlier than typical strains. This generally means you can harvest these plants from the middle of September, and possibly earlier.

Record growth can occur within just a month and a half after planting, leaving less chance for the elements to intervene.

Want to know the best early finish strains to try? Here are our top 10 varieties for no-nonsense outdoor growth.
