Potent Doesn't Even Begin To Describe These 100% Feminized Seeds!

Knockout Seeds are so devastatingly strong that The Gorilla wanted to slap a little Skull & Crossbones sticker across their cute little bums. He settled for a "Tread Lightly" statement instead. Heed that warning or pay the price - stoners who disrespect K.O. always need at least a full day to recover!

  • Knockout or K.O. is Insanely Strong
  • Ready in as Little as 6 Weeks - Bigger & Better at 9
  • A Little Expensive, But You Get What You Pay For!

This is a dyed-in-the-wool killer without the slightest bit of conscience, but don't get us wrong - Knockout Feminized is no couchlocker. These wicked-good marijuana seeds are diabolically potent but in a pleasantly energetic way - social, uplifting and active with just the right touch of mellow.

Don't underestimate the amount of effort Advanced Female Seeds put into these intense 100% feminized seeds! These THC gurus have paid meticulous attention to every detail to create a real workhorse that rises to the top of connoisseur quality & takes a flying leap into sheer bodaciousness. Everything from the power to the flavour is absolutely magnificent!
