“Jack Flash # 5” Feminized Cannabis Seeds – Sensi Seeds

Jack Flash #5 Feminized by Sensi Seeds is a 65% indica and 35% sativa strain. It is a blend of Jack Herer, Super Skunk and a Haze strain. This results in a sturdy plant that is easy to grow and capable of producing large yields.

Jack Flash # 5 has a strong, earthy aroma with hints of pine and citrus. It can be kept relatively compact on the inside, but can reach a height of 250cm on the outside. The high is uplifting and cerebral.

Thanks to the sativa influence, plants can sometimes reach dizzying heights, although they can be kept more compact indoors. The high is reportedly happy, uplifting and euphoric.

Jack Flash # 5 Feminized Cultivation

Jack Flash # 5 feminized cannabis seeds are 65% indica, 35% sativa. The strain was developed by Sensi Seeds, using the famous Jack Herer genetics, combined with a Super Skunk and a Haze strain. It occurs in two phenotypes; one that is more typically indica (compact, stocky, with large buds) and one that is taller and requires more space to thrive.

Characteristics of the cannabis strain

This is the feminized version of the strain. Therefore, the seeds are very unlikely to produce male plants, which makes cultivation much easier. This is beneficial for those who are not looking to produce their own seeds and who want reliability and predictability when growing.

Jack Flash # 5 Feminized by Sensi Seeds has a relatively short flowering time of 55 to 75 days. The phenotype that is most skunk-like in personality tends to be shorter. When grown in optimal indoor conditions, her height can be limited to around 100cm.

The taller phenotype produces much better results when given room to grow. Outdoors, these plants can reach heights of 180 to 250cm (indoors, up to 180cm).

Structurally, both phenotypes differ quite significantly. The sativa type is slender, with thin side branches. These branches are densely covered with heavy buds, which take on the classic spiral formation. The indica type is stocky and bushy, with huge, large calyxes.

Jack Flash # 5 Feminized is a big producer, which is a big draw for growers. Outdoors, the plants reliably produce around 600 grams each, which is a really sizeable yield. Towards the end of the flowering period, the buds are heavy, massive and covered in resin.

This variety performs best in countries with long, warm and sunny summers, such as those in the Mediterranean. Plants also grow well indoors or in greenhouses. The indica phenotype is ideal for the SOG (Sea of ​​Green) system, although growers also report good results from SCROG (Screen of Green), lollipops and supercropping.

Effect, taste and smell of Jack Flash # 5 Feminized by Sensi Seeds

Jack Flash # 5 Feminized is a 65% indica and 35% sativa strain. This blend really comes out in high, which users claim is uplifting, cerebral and happy, while also having a relaxing effect.
