Fast Bud Auto feminized seeds



Fast Bud Auto: Rapid Growth

Fast Bud Auto was developed by Sweet Seeds as one of the quickest autoflowers in their catalogue. While fast, this strain does not compromise on quality and delivers heavy yields of tall, dense, aromatic flowers dripping with resin in lightning fast times!

A strain with Diesel origins, Fast Bud Auto leaves very little to be desired: a compact plant with multiple branches and many bud sites. This strain was designed to be fast; she yields between 400 – 500 g/m2 of large, resinous buds in a short 7.5 weeks from germination making this the perfect cash crop! While this strain is best grown indoors, it thrives in outdoor gardens too. Like most autoflowers, she prefers a minimum amount of nutrients so limited feeding to half the recommended strength. Here is some further information to help you grow this strain:

  • Short plant – depending on phenotype, this strain reaches a final height between 40 – 90 cm indoors and slightly taller outdoors.
  • Max EC of water – 1.0 in veg, up to 1.2 during flower.
  • Water pH; 5.8 – 6.0.
  • Recommended lighting: 600 W LED.
  • Recommended grow style: SoG due to a short height and apical dominance.

Sweet, Aromatic Resin – Perfect for Extracts!

Fast Bud Auto grows with a very typical Indica structure with slightly taller branches with longer internodal distance. This results in flowers with a high bud-to-leaf ratio and a sweet aroma with hints of spice. Fans of aromatic, resin-coated buds will be more than pleased with this strain.
