Price range: $9.00 through $500.00

Critical Jack is one of the top hybrid strains on the marijuana market. It has bagged some serious recognition, taking home the best overall strain in the 1994 High Times Cannabis Cup and first place in the San Bernardino Hempcon Cup in 2015. This bud consists of the genetics of 2 celebrated parents, Critical Plus and Jack Herer. Modest THC levels of 10-15% provide an uplifting high that will not overwhelm. The CBD content of around 2% combined with a rich terpene profile offers some profound therapeutic potential for a myriad of mental and physical wellness challenges. All this awesomeness is delivered on exotic flavored smoke with hints of spice and citrus. These plants are easy to grow from seed too, making them well-loved by tokers and cultivators alike. If you want to buy Critical Jack Auto Fem seeds online in the USA, order through Weed Seeds for grade-A seeds!

Critical Jack Autoflower Seeds

Critical Jack Auto Fem is an amazing strain that tastes delicious and offers many benefits. It is no wonder that people all around the country are eager to add this plant into their home grow operations. There are so many seed shops out there, it can be hard to know where to source your seeds. We acquire our selection from reputable breeders who are committed to genetic purity. We take extra care to store and transport seeds in the ideal conditions so that we can guarantee germination upon arrival into your home grow. We aim to ensure you get awesome seeds and excellent support in your cultivation journey!

The scent of these sticky nugs is quite intoxicating in its own right. Wood and exotic spices underlay an invigorating aroma of tangy citrus. This delightful olfactory experience is enhanced when these dense nugs are busted apart and lit.

The flavor profile is equally exhilarating. Once you light and inhale the thick smoke from a joint filled with Critical Jack, your palate will be hit with hints of peppery spice. A sweet, citrusy tang will linger on the taste buds after you exhale inviting another toke. The best part of this smoke is the smoothness and is not likely to leave you coughing!

These are Autoflower Seeds , which means they do not require light modifications to flower. Breeders discovered that adding in ruderalis genetics not only created hardier plants that are better able to withstand other growing challenges but also created plants that flower without fuss as they move through their life cycle. These Hybrid Seeds are a superb option for a newer grower as they can be grown in almost any light conditions and require little fuss, knowledge, or equipment. If you want to try your hand at growing a few different auto strains, grow Auto Critical X Mazar Fem or Auto Critical Mass Fem to add a little variety into your stash!

We have 450 different strain options to choose from, all of which have detailed descriptions. We want you to be able to easily find the perfect strain to meet your unique needs. Whether you are looking for an indica herb to unwind and lull you to sleep or a heavy-hitting sativa that will invigorate you for the day ahead, we have you covered. We provide regular, feminized, photoperiod, and auto-flowering options so you can buy according to your level of growing experience. Browse our comprehensive catalog and start building your home grown stash!

    Weed-Seeds has a vast selection of seeds compared to other sites. I especially like how they describe the seeds and what you can expect from each plant. Sometimes I have had trouble placing an order but then it goes through. They are slow to update the order status, so even when your seeds are on the way to you, it will show that your order is “processing”. Hopefully, they will change that.

    After 10 weeks, 1/2+ pound yield from such a tiny plant. 20/4 light..1/2 sunlight + 1/2 led/cob. You can grow 4 easily in a m2, giving you 2 pounds+ every 10 weeks if you do it right. Awesome genetics! Would recommend to anyone who wants high yield, potency, and little maintenance in their plants!

    Pretty hands-off after the first couple weeks. Dark period was clean, no leaks. Setup stayed in my tent with a carbon filter humming. Cloned for the next cycle. Glad I waited it out. Post-dry rest went in a stash jar. Lights-off stayed dark the whole way. Dark cycle was sealed up.

    Stretch surprised me once flower kicked in, ran Critical Jack beside a known keeper, swapped Advanced Nutrients weekly and EC stayed calm, might skip unless I need filler, all three beans woke up after an overnight soak, solid vial appeal for the space.
