Membrana is a very special plant, this hyper feminized automatic variety comes from Russia in the city of St. Petersburg, famous for his two weeks of sleepless, where the sun does not set. This variety was tested at this time of the year, exposed to the extreme temperatures in the area with twenty-four hours of continuous daylight, the result was spectacular, and our membranas were flowering smoothly, with an incredible size of 160 cm, with clusters full of resin and coated flowers of remarkable quality for extreme weather conditions and the absence of sun in two weeks. This test was crucial to realize us that this feminized automatic works 100% in the most severe conditions I could find and opened the doors of our catalog.
