Whether you're a seasoned grower or an absolute beginner, these strains offer an opportunity to enjoy the best modern cannabis genetics, swiftly and with confidence.
Three of the famous five are F1 Autoflowers, meaning they're the offspring of two special parent plants created by combining two pure strains. These seeds are the first generation and bring together the best traits from both parents. F1 hybrids are highly valued for their vigor and resilience. They grow faster, are more uniform, and resist pests and diseases better. Plus, they produce bigger yields. When you grow an F1 strain, you get the absolute best. However, it's important not to let F1 plants breed freely for seeds. Their offspring, known as F2 plants, can be less predictable and less stable.
Get ready to be mesmerized by the sheer diversity and potency packed into these five extraordinary cultivars.
