Jack Herer Auto Review

14

jack herer autoJack Herer is one of the most popular regular photoperiod strains out there and since in the last couple of years autoflowers have become very popular amongst new growers, seed breeders have crossbred the original Jack Herer with ruderalis genetics creating auto Jack Herer. This plant is a middle of the range grower with average yield and average growth but that is a good thing as this is not one of those bonsai plants and not a super auto that will grow huge. You can get up to 120 grams per plant and the height is usually from 40 to 90 cm so you can grow this strain in smaller cabinets as well as full-fledged grow rooms.

Strain

Jack Herer Autoflower strain is a Sativa dominant plant with about 40% sativa, 30% Indica and 30% ruderalis genetics and that gives Jack Herer auto this advantage of being autoflowering plant but still giving a great yield.

The original Jack Herer plant is a crossbreed of Northern Lights and Haze plants and that means strong genetic makeup and great growth. Today you can find many different Jack Herer autoflowering seeds from many different seed breeders like Royal Queen seeds, Female seeds as well as Advanced Seeds and Greenhouse seeds and you have to look around before buying this plant. In general all these seed breeds are almost the same and they have only small variations in their growth. The original Jack Herer strain was created in honor of the cannabis activist with the same name who created one of the best selling cannabis books “The Emperor Wears No Clothes” and was also called Emperor of Hemp. And this autoflowering cross is a great legacy to a strain with great heritage and humble beginnings that is named after a great person.

Auto Jack Herer growing

autoflower jack herer Jack Herer autoflowering strain is an easy plant to grow and I have seen great results from indoor and outdoor grows as well as some low light balcony grows and even first time growers can get a decent yield from this plant. This autoflowering strain usually takes from 65 to 80 days from germination till harvest and depending on the grow room conditions and the genetics you can get your buds ready in that time period. I have seen some early harvests on day 65 and some great buds on day 75 so the average age is about 70 days. And because that is a bit more than some super fast autoflower strains Jack Herer will give you a bit more yield and gan give up to 120 grams in optimum growing conditions but usually the yield is anywhere from 20 to 60 grams per plant. Of course if you use CFL lights and a small pot the yield can be greatly diminished but you should still get a couple of dry grams at the end of your plants growth. Auto Jack Herer is a great strain for first time growers as it is very resistant to pests and can tolerate stress caused by inexperienced growers like under or overwatering or too much or too little nutrients. You can even use some LST methods and even HST like topping if you want but the best results can be achieved with an organic growth without any training. Autoflowering Jack Herer can be grown either indoors or outdoors and as well as in soil, soilless mix and hydroponically but of course the best results usually are from hydroponic growth but that requires a lot of equipment and specific knowledge. For first time growers you can just take these Auto Jack Herer seeds and put them in the soil that is potted in a 2 or 3 gallon(7 to 11 liter) pot and after the initial seedling growth phase start adding some ¼ strength nutrients and you should have a great harvest after 2 and a half months!

Yield and harvest

jack herer auto before harvest

Jack Herer Auto Flowering plant as I mentioned earlier will be ready to harvest in about 65 to 80 days with the average time being around 70 days from sprouting. You should harvest your plant only after about half of the trichomes have turned amber if you want to get that 15% THC mark that breeders specify on the packaging. Because this strain has some ruderalis genetics then the CBD as well as CBN ratios will be a bit higher and that is great for medical users and if you wan to get a more “body” high then you can let the plant mature a bit more till about 70% of the trichomes have turned amber. Because Jack Herer is sativa dominant strain the buds will be a bit more widely spaced and that means that the harvest will be easier and you will have more room to cut down those fan leafs and to manicure those dense buds as well as there will be lower chance of molds in those bud sites.

Smoke & Smell

Jack Herer automatic plant will start to produce odor almost as soon as the first pre-flowers will emerge and you will definitely need a carbon filter or other filtering mechanisms to mask that skunk and herbal smell. As the harvest approaches the mell will get more and more intense and even after harvest you will be able to smell the great aroma that this plant produces. The smoke will be a mix of both that body high as well as a head high and after consumption you will first experience a great uplifting feeling and a great surge of energy but after some 20 to 30 minutes you will start to feel that body high that will push you to sit down and enjoy life. The taste of the smoke is very similar to the original non-automatic Jack Herer strain and it has a herbal and spicy taste but because of that a little lower THC content autoflower Jack Herer will be more mellow and better for first time users. In my perspective this strain is not the best autoflower that I have tasted but it can be a great so called daily-driver for most people and I can’t complain neither about the taste or about the high!

  1. First time auto grower doing J Herer in DWC plants well over the 90cm mark I’m on day 65 of flower and wishing the buds had a little more to them, continuing to flower in hopes that they plump up. Besides that I have no other complaints.

  2. I planted my germinated seeds on June 2nd. It is now September 16. that’s 3.5 months. The plants have been outside in a green house. There are great colas on the plant but after all this time, I would have thought they would be ready to harvest by now. Trichomes appear clear at this time. WTH?

  3. 3 JHA started July 27th, today (Oct. 12th) is day 77, or 11 weeks. One looks like what I have seen online, thick tight buds, under microscope long orange threads, with trichomes 90% milky, very good. Not sure on maturity rates, but looking like maybe 14 weeks, before harvest. Two plants look more alike than the one above, looser buds forming, but not going to produce the gram weight of the best plant. First time growing, lots of beginners mistakes, learning fast. Next grow will be all in a grow tent, its critical to control the environment. Will start a different strain next grow, its been fun.

  4. Got one which I didn’t know was Auto but which is in flower now at the end of two months. It is about 90cm high and very large leaves. Buds forming have red hairs. I’d be surpised if it didn’t manage to reach the 120 grams listed. Until it started budding it was going faster than anything else and I was expecting a regular photo-period plant. Glad to have something for Christmas anyway. We’re in the Southern Hemisphere by the way and this is outdoors.

    First time grower. i wonder if i can grow this seed indoor with multi Spektrum 200w cfl lamb? and is harvest time is important when growing indoor?

    • I think that you most certainly can, and usually the harvest time is just an approximate time and the real growth time will depend on almost all the growing factors starting from lights to nutrients and temperature.

    My Auto JH popped on Jan 1st, 2017. It is from advanced seeds. I am growing it in a pot with coco, vermicompost and perlite. It is growing in my balcony and not under lights as I live in a country in south east Asia and getting grow lights and tents etc are difficult and expensive. Though it is winter now, because of the tropical climate where I live, I am getting uninterrupted direct sunlight for at least 8 hours a day. Do you think that should be enough for the autos to get a decent yield? Also, on day 12 since it popped, it had got 2 sets of true leaves. But I checked a few grow diaries and videos for Autos and noticed that most of them had at least 3 to 4 sets of true leaves by day 12. Is it because of getting only 8 hours of direct sunlight? Also, I have bought micro and macro nutrients and the instruction says to use and dilute about 5ml to 1 litre of water. What it does not mention is how many litres of nutrient filled water I need to be feeding my plant. Any suggestions? Thanks in advance. BTW this is my first ever grow.

    • Autos are tough and I think 8 hours of light will be enough to get a couple of grams from your plants, but of course they would do better with more light.

      Those nutrients could be made to add with every watering but if you do so be careful as autoflowers need less nutes than regular photo-sensitive plants.

    I got the Jack 47 Auto as well and I’m two months in and I have not seen a flower yet it’s 68 cm tall with a stock thicker than a quarter and all the branches thicker than dimes big thick arms with multiple branches coming out looks beautiful just wondering when the hell is going to flower

  8. I grew and smoked the JH autoflower & it is a very good uplifting and happy lift. It does not have the sluggishness that some ruderalis plants have. It starts with a body numbing feeling similar to blue dream and then goes to a light hearted and very happy and contented feeling of peace and oneness and acceptance. It’s a GREAT autoflower. For an autoflower, it is pretty clear bright and inspiring. It feels like a genuine sativa.
