Flash Seeds was started up recently by an experienced auto-flowering seed aficionado. He’s been a hobbyist for decades and has cultivated his own unique strains after years of advanced experimentation in his secret laboratory. Some of these strains are true monsters, with many of his Sativas reaching 2-3 meters high while still being an auto-flowering strain. That is absolutely staggering and outdoes many of the regular seeds on the market. True Super-Automatics from a breeder who is passionate about his research. What more could you want?

We’re all about supporting new breeders, as long as they can put their money where their mouth is when it comes to strains. I fully vouch for Flash Seeds, these babies are some of the best Auto-flowering seeds on the market. Absolutely massive yields while shooting up in the sky at record-breaking speed. Many of these are Sativa-dominant strains, to an extreme amount. Flash loves his plants to be gigantic, and Sativas are the plant for it. Check out the catalogue, Ice Head Shop is bringing you the best deal on these truly unique strains.
