Ultraviolet Auto feminized seeds


The Ultimate Lavender Autoflower

Ultraviolet is a feminized autoflowering cannabis strain brought to you by Samsara Seeds. A Sativa-dominant autoflowering strain, it was initially crossed between White Dwarf and Skunk followed by Lavender, which gave its main characteristics including her beautiful purple color, dense buds and high resin production.


A Beautiful Plant with Violet Hues

Growing Ultraviolet is a pleasure for any grower. Having a strong genetic lineage, this strain is totally worth all efforts. Due to its Sativa genetics, Ultraviolet tends to grow to a medium height, slightly taller and more spindly than some of the other White Dwarf x Skunk crosses in the Samsara range. Well cared for gardens can yield up to 400 g/m2. This strain is known for its excellent resistance to mold and to pests such as fungus gnats and thrips which makes this the perfect choice for a beginner. To bring out the cyano-pigments that give the purple bud colour, ensure that daytime temperatures do not exceed 23˚ C from mid-flower until harvest.

  • Max EC of water – 1.2 in veg, 1.4 in flower
  • Water pH; 5.8 – 6.0

Sweet and Purple

Ultraviolet has a phenomenal smell, taste and appearance; it has lovely pale green and purple buds covered in a dusting of trichomes. These frosty nuggets are sticky to the touch and leave your fingers covered in an aromatic resin containing myrcene and pinene amongst other terpenoid compounds.
