Black Jack CBD by Sweet Seeds is a strain that’s been developed for medicinal users thanks to its THC:CBD 1:1:5 ratio, and the CBD content can reach up to 17%. This strain comes from an amazing Black Jack with a meticulously selected Diesel clone that has high CBD levels. Thanks to this cannabinoid concentration and its high resin yield, you can use it to get some potent medicinal extracts.

Black Jack CBD Grow Indoors and Outdoors

How to grow Black Jack CBD indoors

When grown indoors, this strain can be a fast and constant stream of top quality medicinal marihuana – it will be ready just 9 weeks after germinating the seed. It has quite a compact, strong and empty structure, so you can place 16 plants per square meter to make the most out of them. They’re a bit delicate when it comes to feeding, and we recommend keeping control of the pH and EC levels; you can get up to 500g per square meter.

How to grow Black Jack CBD outdoors

When grown outdoors this strain does best in mild climates, as it has a slight resistance to low temperatures; more so than excess light. It has quite a sativa structure outdoors, with a large central stem, separated nodes and long, scarce branches. Its indica genes allow it to keep control of its high, however, and it will grow to a maximum of 2 months. You can get up to 700g per plant, and they should be ready towards the end of September.

Black Jack CBD Seed Properties

This plant has the same original Black Jack flavor; sweet and incensed tones with a marked lemon aftertaste in some phenotypes. Due to having such a balanced cannabinoid content, this plant has a smooth physically relaxing sensation which is capable of calming many different kinds of pains and disorders. It won’t change the mood of whoever consumes it, allowing you to simply make the most out of the medicinal effects throughout the day.

  • Sativa/Indica: 50/50%
  • Flowering: 9 weeks indoors, end of September outdoors.
  • Height: 0.5-1m indoors, 1.5-2m outdoors.
