F1 Hybrid Cannabis Seeds

There are 18 products.

As the latest development in the world of cannabis genetics, F1 hybrid seeds are a real game-changer. Focused on producing plants with higher THC levels, massive yields, and, most of all, exceptional uniformity, these seeds are sure to appeal to all manner of growers.

True F1 hybrid seeds are created by crossing pure (aka highly inbred) genetic lines. This time-intensive practice has been part of the vegetable and ornamental gardening industries for many years, and is only now entering the cannabis cultivation industry. Each F1 hybrid seed will produce a robust, resilient, fast-growing plant that's nearly identical to the next. Currently available in autoflowering form, F1 hybrids are easy to grow, without making sacrifices in other important areas—just see for yourself.

Get your pick of the finest F1 seeds right now at Zamnesia.
