Jack Herer Feminized Cannabis Seeds

Jack Herer feminized cannabis seeds are named for the well-known and much-respected advocate of the industrial hemp legalization. An enduringly popular recreational and medical strain, Jack Herer is also recognized as a medical-grade pharmaceutical in the Netherlands.

Jack Herer Hybrid Cannabis Strain

nearly balanced hybrid, Jack Herer brings to the table the best of both Sativa and Indica effects. Users generally find they are happy and calm after consuming the orange and lemon-scented vapor, but alert enough to carry on conversations that are bound to get interesting thanks to the strain’s ability to “Jack” up creativity.

Jack Herer Effects

You will notice a healthy deposit of sugar-like trichome resin on your Jack Herer plant, despite the level of Sativa. This sticky surface is what offers those calming, blissful effects that play along so nicely with the more euphoric Sativa qualities the strain provides. Depending on your tolerance and body chemistry, you might find yourself more energized, or deeply relaxed. A moderate THC level of about 18% means you’ll get the heady buzz for which cannabis is known, but should avoid any overpowering psychoactive effects. The effects of Jack Herer tend to be long-lasting.

Medical Jack Herer Cannabis

Medically, our Jack Herer cannabis seeds grow into medium-height plants that provide relief from the symptoms of depression, soothe away stress and anxieties, and reduce pain. The strain is not recommended for nighttime use since, despite the relaxation, users often find themselves too attentive to nod off – avoid this strain in the afternoon and evening if you struggle with falling asleep.

Jack Herer Seeds

Jack Herer cannabis seeds have a relatively short flowering period of 50 to 70 days. Large, round buds provide a good yield both indoor and out, though the medium height and compact body of Jack Herer makes it an ideal choice for indoor growing. You can expect up to 500 grams of harvestable flowers from each square meter of indoor growth, and gardeners with moderate experience should find the growing process quite straight-forward.

Jack Herer feminized cannabis seeds infuse you with creative, calm alertness.

    Always the best in the bunch. I am a huge stoner, but new to growing my own, so decided to try this one out cause I have purchased it from the dispensary many times. Great stuff! Easy online ordering and super fast delivery to my home. Got an excellent growing experience from this and really enjoyed the process of watching the flower form into tight little nugs. It’s super sour and very uplifting. You can’t go wrong!

    Jack herer is a classic…something I’ve been smoking for at least the last 10 years. I never thought to grow my own mj, but I am Sooooo glad I decided to try it out. Maybe it’s the genetics in the seeds, but these guys sprouted beautifully, and they grew up super fast in my greenhouse out back, an absolutely stunning plant with incredible color and aroma, it’ll impress your friends too. Definitely has a citrusy taste and gives me a BOOST of great energy!

    This weed gets me JACKED up, and I get super excited about life! I love socializing, and I love moving around, it’s basically like adderall for me, increases concentration, and I even feel a little bit creative! I got myself 20 seeds from Green Leaf and planted them in the backyard, and they did super well back there in all the sunlight and whatnot…had to water them fairly frequently, but that’s no problem…Got a nice yield, and very fresh nug 🙂

    I’m a return customer, I’ve been buying from green leaf ready for a long time and this has been my go-to for a while now. It’s an easy grow, a classic strain, very well documented and easy to follow, and hey, the grow guide on this site is super helpful! The buzz is solid! Its easy breezy and great for my stress and my mind. Now I can finally relax after work, and feel good about the night ahead. Depression doesn’t stand a chance!

    If you’re a fan of hybrids this one is definitely top of my list. It’s a classic mj strain, and it’s actually really hard to find in Canada! Got my seeds delivered in no time, so easy to order online! and the smell of this herb is so sour and sticky and dank, I am pretty stoked about how this turned out, and how well my plants did out back. Good stuff for sure!

    On my new property, I finally have a ton of space to grow weed! Got a big old greenhouse built out back, with indoor lighting and everything, so everyone in the neighborhood will want some haha! Jack herer is an all-time fave. I’ve grown it before, gotten some nice results, but something about these seeds took it to the next level. Maybe it’s the genetics? Who knows? Either way, I am really happy with the quality of this weed!

Not difficult to grow and the seeds were very responsive to my tending. Looks great in the garden and is loved by everyone in my household. A staple stoner crop!

    If you’re looking for that warm fuzzy feeling when you smoke, this is the perfect strain for that. It’s a nicely balanced hybrid that has been great for my anxiety, depression, and overall fatigue. I love the smell and taste of Jack Herer, it’s amazingly sweet with a hint of sour earthiness. Its something to share with friends or just chill in the park with on a sunny afternoon!

    The perfect daytime strain for stress and anxiety. I have a very stressful work life, I am always on the clock and need help relaxing and staying focused. Jack Herer is my go to for sure. It was easy to grow in my basement and has these bright green and orange nugs. It’s been very useful during the work week in calming my mind and helping me stay focused!

    Wow if there ever was a perfect backyard strain this would be it! Jack Herer is a classic, almost any stoner you know will have heard of it or smoked it at some point. I was amazed at Glr online collection so went with a safe bet and was NOT disappointed! A great grow, super fun and even pretty quick too! I got a GREAT yield and smoke this stuff every afternoon for a burst of creativity and life!

    This is my favorite strain of weed, have been smoking it for years! It’s a well balanced hybrid that will keep you feeling both energized and calm. It’s fun to grow and the seeds were shipped out super quick. I got all 20 of my seeds to germ and then only 3 months later I started seeing beautiful green crystals! A great anytime weed, perfect for afternoons or weekends. Has been helpful with stress and anxiety as well as mood.
