Strain description

3rd Generation autoflowering strain. Tall-stemmed version of one of our most appreciated autoflowering strains, the amazing Jack 47 Auto® (SWS31).

Jack 47 XL Auto® (SWS78) was developed through a recurrent selection programme of tall-stemmed and high production specimens of Jack 47 Auto® along multiple generations.

This is a high yielding autoflowering strain that preserves a powerful hybrid vigor. The plants develop compact buds covered in outstandingly aromatic resin. The tastes and aromas of this genetic are sweet and fresh, with lemony citrus tones and a touch of incense. Probably one of the most powerful autoflowering strains in the market.
