Description
Black Jack Seeds Info
Available as feminized seeds with an equal mix of Indica and Sativa, Black Jack is well-suited for growing in both cold and warm environments, indoors or outdoors. The smoke will give you a boost of happiness while keeping you extra relaxed for quite some time.
Genetics
A direct descendant of Black Domina and Jack Herer, Black Jack is like an encyclopedia of Old World genetics. Her family tree includes Northern Lights, Ortega Indica, Hash Plant, Afghani, Shiva Skunk, and Haze – amazing seeds, every one!
Effects
Buds grown from these seeds will relax you while making you feel undeniable happiness and euphoria with the right amount of energy – perfect for stress relief and lessening depression.
THC And CBD Levels
THC levels hover around 16-20% when harvested at the right time, while the CBD content remains at 1%. This is enough for Black Jack to draw its serious healing properties from both cannabinoids.
Smell And Taste
Black Jack has an herbal and sweet yet spicy and woody flavor, almost incense-like, with just a touch of citrus. This makes for a very interesting mix of terpenes to help these seeds seriously stand out from the crowd.
Yields
Outdoors, these seeds guarantee about 500-700g (17.6-24.7oz) per plant. Grown in a tent, they yield about 500-600g/m² (1.6-2oz/ft²).
Flowering Time
Black Jack needs 9 weeks to bloom indoors and is ready to harvest in early October if you choose to plant these seeds outside.
Grow Tips
Growing this resinous lady doesn’t require a lot of experience. In fact, a novice grower can have a successful cultivation following just a very basic routine. Black Jack can reach 3m (10ft) in height if planted outdoors, becoming a beautiful giant with many hairy heads. If planted indoors, the plant behaves more moderately, growing to only about 1m (3.3ft).
- Control the height indoors with the size of the container.
- Make the veg longer to get bigger plants at harvest.
- She’s a branchy plant, so be sure to prune lower branches and defoliate.
