Black Jack F1 Fast Version > Sweet Seeds

Feminized and non-autoflowering version with an ultra fast flowering of one of the first and most appreciated strains of Sweet Seeds' catalogue. The Black Jack F1 Fast Version marijuana seeds hybrid is the result from the cross between a selected strain of S.A.D. Auto and the Jack Herer elite clone used in the original Black Jack. Just like the original version, this strain produces very potent and productive plants, with strong side branches that are very long and fully loaded with aromatic flowers.

 

The aroma is very sweet and with hints of incense complemented by lemony citrus tones. This version shortens flowering time about one week comparing to the original version without any loss in quality or quantity. The available "fast version" strains of Sweet Seeds (FV/F1) are created by cross-breeding of an autoflowering and non autoflowering strain. Through the selective introduction of autoflowering genes, Sweet Seeds managed to reduce the flowering period of this strains.

 

The results are non autoflowering plants, but having a significantly reduced flowering period, without any losses of quality or quantity. All these strains available as "fast version", as opposed to the original version have a shorter flowering period of about a week. That makes it interesting for commercial growers, but also particularly suitable for outdoor growing in cooler climates.
