Filled to the brim with flavor, potency, and benefits!
Jack Herer pays tribute to the legendary cannabis activist and best-selling author of The Emperor Wears No Clothes. It’s a 60% Sativa, 40% Indica hybrid, which many fans call the “perfect mix.” Sensi Seeds initially developed it, but the strain has been refined into what we now know – a therapeutic cannabis strain that produces dense buds with a pleasant cerebral high.
Jack Herer has gained so much notoriety over the years. It was created in Holland in the late 1990s by crossing Northern Lights#5, Shiva Skunk, and Haze. Initially intended for medical marijuana patients, the strain brings happy, soothing effects and potent therapeutic properties. Many people still rely on Jack Herer for their mental and physical health, especially to ease stress and pain. However, it is also known for giving a happy, clear-headed feeling of euphoria. This is an excellent morning bud that energizes and puts people in a good mood.
Jack Herer comes in autoflowering, regular, and feminized seed varieties. It is simple to grow, even for beginners, and can be cultivated indoors or out in a dry and warm climate.

Jack Herer is available in regular, feminized, and autoflowering seeds. To know which one is best for you, we’ll discuss the differences between the three. Note that it is impossible to tell the seed type through physical inspection.
Regular cannabis seeds have a 50% chance to become male or female, just as nature intended. Regs are very popular with breeders who want to create new strains. They use the pollen produced by males to fertilize female flowers and produce seeds or their own strains. When creating a new variant, you can choose plants with the traits you want. Anything can be modified, including the terpene profile and cannabinoid content.
To maximize the chance of germination of female plants, feminized seeds were developed. The chances of female germination are 99.9%. If you prefer flowers to pollen sacs, the odds are in your favor! Feminized seeds will give you only resinous buds. It will save you a lot of time by not having to remove males from your growing area. Your garden or grow tent will be pollen-free, so you can rest assured.
These are feminized plants. Contrary to male plants and female plants, these are the ones that produce consumable weed. They flower when they get less sunlight per day. In the Fall, or when you alter the light cycle indoors.
In contrast, plants that grow from autoflower seeds start fruiting in a matter of weeks regardless of the light conditions. These plants are smaller than photosensitive plants, but they can be grown much faster and produce more fruit. They are great for beginners, small spaces, and multiple harvests.
Autoflowers boast genetics from ruderalis plants, a type of cannabis found in Siberia and introduced to Amsterdam in the early 1980s.
Jack Herer is resistant to most diseases and, therefore, easy to cultivate. This strain is often called a “grower’s dream” because it can produce high yields and flower quickly.
Jack Herer loves to grow bushy, so ensure sufficient spacing between plants. Also be aware of the stretching involved in growing the Sativa variety to prevent it from outgrowing your space. To avoid its branches from snapping, ensure they are adequately supported as they grow. Giving silica-based plant food also helps develop thicker stems that support their buds.
Jack Herer thrives in dry, Mediterranean climates and is an excellent option for hydroponics systems. Indoor hydroponic gardens, where temperature and feeding can be controlled, can produce 500 grams per square meter after nine weeks of flowering. Outdoor growers can expect similar yields with harvests in late September or early October.
Overfeeding Sativa-dominant plants is possible and quite common for beginner growers. Be sure to start slowly and watch out for any nutrient blockage. If you feel you have been overfeeding, you can flush the Jack Herer plants.
Jack Herer can be grown as an autoflowering variety. It doesn’t need to be exposed to a certain amount of sunlight to thrive. It also switches automatically from the vegetative phase to the blooming stage. Even better, the plants will flower quickly and be ready for harvest earlier.
Novice weed gardeners can use auto Jack Herer seeds. Its small stature (rarely more than three feet, even with space restrictions) and its resistance to pests and diseases make it ideal for those new to gardening.
This compact cannabis plant thrives in both indoor and outdoor settings. You won’t need to spend much time or space in either situation. In 10 to 14 weeks, it is ready for harvest. Mimic a Sativa-preferred climate if you’re growing indoors. High temperatures between 70 to 85 degrees Fahrenheit are most beneficial.
This high-yielding autoflowering variety produces approximately 150 to 450grams per square meter indoors. When grown outside, Jack Herer auto can share a harvest of between 400 grams of cannabis flowers per plant. You can expect better results if you live in a Meditteranean climate. However, some cold is not an issue. You can start sowing after the last frost has disappeared, collect by late May, and start another grow for two harvests per season.
Hydroponics and the Sea of Green setup allow for maximum harvest potential. SOG is a low-stress growing method that allows you to grow a large number of small plants in a very limited space. Your crop will look like a green sea, as the name implies. This method allows for a shorter growth cycle. They can also increase their annual harvests.
The plants in a sea of green setup are often grown in small containers that allow for dense packing in the grow area. Grow of the side or lateral budding sites is discouraged in favor of a well-developed apical cola.
Hydroponics in Sea of Green requires that you dial in your system to perfection. Hydroponics can grow plants faster and more efficiently than soil, provided it is correctly set up. The best hydro setup for SOG growth is a tray that floods and drains (more commonly known as ebb and flow).
