Killer Kush F1 Fast Version feminized seeds



Your Favourite Kush – Now Much Faster!

Killer Kush F1 Fast Version is a feminized photoperiod cannabis strain developed by Sweet Seeds as a cross between an Indica-leaning autoflower and a remarkable phenotype of OG Kush to create a plant with the yield, effect and aroma of OG Kush but with a much shorter flowering period.


Once you’ve tried it, you will thank yourself for growing Killer Kush F1 Fast Version as she offers excellent yields of chunky, resinous buds in lightning quick flowering periods! In addition to having a sweet and musky terpene profile, this strain has up to 25% THC making it one of the strongest cannabis strains available on the Sweet Seeds catalogue. Indoors yields for this strain are between 400 – 600 g/m2 after a 7-week flowering period while outdoor growers can expect to harvest up to 600 g/plant in early September. Here is some further information to help you grow this strain:

  • Medium height – reaches a final height of 1 m indoors and 1.2 m outdoors.
  • Max EC of water – 1.4 in veg, up to 1.8 in flower.
  • Water pH; 5.8 – 6.0.
  • Recommended lighting: 450 W LED.
  • Recommended nutrients: Advanced Nutrients pH Perfect® GROW, MICRO, BLOOM.

Killer Kush F1 Fast Version: A Potent Indica Power & Pungent Aroma

Killer Kush F1 Fast Version has a smell, taste and appearance which is almost identical to her parent OG Kush – a sweet, pungent aroma with notes of spice and sandalwood which comes together to create a well-defined terpene profile. Her effect is relaxing and begins as a cerebral buzz but slowly progresses into a relaxing body high.
