Alpen Gleaux F4 Feminized Autoflowering Hemp Seeds

Alpen Gleaux F4 feminized auto-flowering hemp seeds are a collaboration between Alpine Genetics and the veteran-owned and operated Phoenix Farms. Alpen Gleaux F4 was organically grown and selectively bred from F3 stock for structure, color, and yield. 15 males were planted and culled down to three select studs. Then over 40 females were planted and culled down to a dozen beautiful, insanely purple, terpene-laden, Cannabidiol (CBD), auto-flowering females. These plants not only produce great smokable hemp flowers, but they also make fantastic concentrates!

These are very homogeneous seeds with two main phenotypes to be found:

The first phenotype is stouter, with lots of lateral branching. Expect one main cola with sticky, purple buds and loads of trichomes.

The second phenotype is taller and can be topped, or “fimmed”, early on, if height is an issue. Again, expect large purple buds with lots of lateral branching.

Great for commercial growers, both phenotypes produce large buds and average 80 days from germination to harvest. Terpenes on these ladies remind me of perfume and redwood trees.

These autos need extreme caution when transplanting. Direct sowing into a final pot is ideal. Do not start these seeds in trays.

Why plant industrial hemp with low CBD levels when you could plant high CBD hemp (20:1) ensuring your crop stays federally compliant while getting the most out of your grow?

Averages 80 days from seed to harvest, great for concentrates and commercial growers!
