Black JackF1 Fast Version®

Black Jack Fast Version F1 by Sweet Seeds is a plant that has plenty of dark colors and gives large yields outdoors and indoors especially.

This SAD x Jack Herer combination takes even less time to flower – the original Black Jack would take around 11 weeks whereas this one takes just 8, reducing the wait by three whole weeks. Everyone wants to get their hands on its incensed, resinous buds as soon as possible without sacrificing yield or quality, and we can guarantee that this strain won't disappoint.

Black Jack Fast Version F1 Indoors and Outdoors

Indoors this version of Black Jack should finish flowering after 7-8 weeks of 12/12h lights, making it much faster than the previous versions. You can get an easy 500g per square meter from this plant. It’ll yield a bit less, although its flowers are just as potent as the original strain’s. This stable plant will astonish you with its incredibly fast flowering period.

Outdoors it should be ready to harvest towards mid-September, allowing you to harvest up to 700g from just one plant if the weather’s in your favor. It needs a lot of light and not much water, so make sure you don’t accidentally overwater it; you let it dry out enough, it’ll grow larger roots which means a much larger plant. For best results, use Dense Bud Compactor.
