Cannabis seeds BLACK JACK F1 FAST VERSION® from Sweet Seeds

Sweet Seeds has taken a final leap towards success with their third-generation feminized cannabis seeds, Black Jack F1 Fast Version.   By re-crossing the genetics, the latest fast version has increased hybrid vigour, resulting in higher yields and even more pure traits from the original Black Jack strain.

The R&D Department's partners finalized the most decisive element. They took confident action and managed to shorten the flowering time to an unprecedented 49 days.  As a result, Black Jack F1 Fast Version cannabis seeds now have an ultra-fast flowering time while preserving the well-known powerful effect from the previous version.

This version is a cross between a specially selected SAD Auto strain and Jack Herer cannabis seeds. After achieving the desired result, we used the specially selected clone Black Jack, which had the most stability and the correct growth sequence, in the original strain. Although this process can be described in just two to three sentences, it took years of incessant labor to accomplish. We overcame many problems and failures during the crossbreeding process. However, the appearance of a new variety from the Fast Version line could not be prevented due to the tenacity of the creators. This group has not only developed cannabis seeds that mature quickly but also promotes cannabis cultivation in northern latitudes with shorter summers and harsher frosts.

Sweet Seeds' Black Jack F1 Fast Version can now be grown in new locations. This success benefits all growers who want to harvest in mid-September and be satisfied with the final product.  The strain produces vigorous buds with strong, long branches, and in the last weeks of flowering, it emits a pleasant sweet fragrance with hints of lemon.

This version shortens flowering by one week and is ready to harvest in mid-September. For those who love Sativa and need early maturation, we recommend buying feminized marijuana seeds Black Jack F1 Fast Version.
