Jack plant from Advanced Seeds


The flowering time of the Jack Plant strain (feminized) is 60-70 days, which is initiated by the photoperiod. The high THC level of 20% in the marijuana gives it a powerful kick and a typical, energizing sativa high. An impact that you have almost definitely never felt before is really extraordinary!

Generous harvest yields are already something you can anticipate. You can grow plants indoors at 400-500g per square meter. The plant only grows to a height of 75-150 cm here. To best utilize the plant’s potential, you should calculate additional room in this instance as well. Small niches are not the best environment for growth.

When grown outdoors, the plant, which is more appropriately referred to as a cannabis tree due to its enormous growth, may produce yields of up to 1,000g per plant.
