Amnesia Haze Feminized at a glance: Amnesia Haze strain is an 80/20 sativa dominant plant that flowers in 10 to 12 weeks, tests 20% to 24% THC, yields 550 to 650 g/m² indoors, and delivers a sharp lemon and earthy incense flavour with a fast, energetic and very talkative high.
A long-flowering sativa for indoor Canadian rooms, shipped from Vancouver
Amnesia Haze strain needs 10 to 12 weeks of flower, which is a long time to wait for a plant and no time at all compared to an overseas seed order. Ours never leave the country: the packs sit in our Vancouver, BC seed bank, go out in plain unbranded packaging the day payment clears, and reach every province in 3 to 7 business days. That matters most with a strain like this, where the grow is a full season indoors and a delayed start pushes your harvest into the new year. We germination test every batch in Vancouver before packing it, stand behind each pack with the 80% germination guarantee, and give you a second pack free on every 10 and 25 seed order.
Where Amnesia Haze comes from
Amnesia Haze strain is a polyhybrid rather than a simple cross. Its family tree pulls in Haze along with Thai, Jamaican, Hawaiian and Cambodian landrace sativas, then anchors all of that with Afghani and South Asian indica to keep the plant from growing forever. The version sold today was assembled in the Netherlands in the early 2000s and became a permanent fixture on Amsterdam coffee shop menus, collecting Cannabis Cup recognition along the way.
The name is a joke about the effect rather than a description of the genetics, and it has stuck for two decades. What makes Amnesia Haze worth growing now, in a market full of 30% indica crosses, is that almost nothing else offers a true sativa structure, a huge yield and a citrus profile all at once.
Amnesia Haze strain effects and experience
It hits quickly, usually within ten to fifteen minutes, and the first thing most people notice is that conversation gets faster. The effect is strongly cerebral: energetic, creative, sociable, with a slightly psychedelic edge at higher doses and very little body weight behind it. That makes it a daytime plant rather than an evening one.
At 20% to 24% THC it is potent, and the speed of the onset catches people out more often than the strength does. The flip side of a pure sativa effect is that it can be too much of a good thing at a large dose, so a small amount and a twenty minute wait is the right way to meet it.
Amnesia Haze flavour, aroma and appearance
The aroma is lemon first, sharp and clean, followed by earthy incense and a faint sweetness that some people read as spice. Ground up it gets peppery. The smoke is smooth for something this citrus-forward, and the lemon carries all the way through the exhale rather than disappearing after the first note. Terpinolene and limonene lead the profile, which is the signature of the haze family.
The buds are long and slightly tapered, lighter and less dense than a modern indica cross, with a thick coat of trichomes that shows as visible crystal rather than a frosted sheen. Colour stays bright lime green with abundant orange pistils.
Growing Amnesia Haze in Canada
Indoors
This is the setting Amnesia Haze was made for in a Canadian climate. It stretches roughly two times after the flip, so veg for three weeks at most and expect 100 to 140 cm at harvest. Keep the room bright and warm, 24 to 27 degrees, with humidity around 50% through mid flower; the airier bud structure means rot is far less of a threat here than with a dense dessert strain. It is a hungry plant and will take a full feeding schedule, but watch magnesium in weeks four to six when the lower leaves start working hard. The long flower is the real cost: budget 70 to 84 days and do not harvest early, because the citrus terpenes and the clarity of the effect both develop in the last fortnight. Our indoor growing guide for Canada covers the light and airflow setup that suits a plant this tall.
Outdoors, by region
Be realistic about this one. A 10 to 12 week flower puts the natural outdoor harvest in late October or November, which does not exist as a growing window anywhere in Canada. In a heated greenhouse with supplemental light on the Lower Mainland or Vancouver Island, it can be finished, and southern Ontario growers have managed it in a polytunnel in a warm year. Everywhere else, and in any unprotected garden, the frost arrives first. If you want a haze-style plant for an actual Canadian outdoor season, our best outdoor seeds for Canada guide lists the strains that finish in September.
Height and training
Top at the fourth node and net early, because Amnesia Haze grows long, flexible branches with wide internode spacing and will happily produce a dozen tall, thin colas instead of a canopy. Low stress training in veg does more for the final yield here than anything you can do in flower. Supercropping the main branches in the first ten days of flower keeps the tops level under the light.
Flowering and harvest cues
Haze plants throw fresh white pistils deep into flower, which makes them look perpetually unfinished. Ignore that and use a loupe from day 65. Cloudy trichomes with almost no amber gives the sharpest, most energetic result, which is what most people want from this strain; letting it run to 10% amber softens the effect and costs some of the lemon. Dry at 17 to 18 degrees over two weeks and cure for a month, because the incense note needs time to settle out of the citrus.
Amnesia Haze yield indoors and outdoors
Amnesia Haze is one of the biggest producers we stock. A well trained indoor canopy returns 550 to 650 g/m², and a greenhouse plant with a long veg can give 600 to 800 g dried. The buds are lighter than they look, and the trim takes longer than average because of the leafier structure. Measured against the calendar rather than the square metre, a 12 week flower means fewer cycles per year, which is the honest trade to weigh.
Who Amnesia Haze is for, and who should pick something else
Grow Amnesia Haze if you want a real sativa rather than a hybrid described as one, if you have the patience for a long flower, or if you want the largest indoor yield in the sativa category. It suits growers who run one or two long cycles a year rather than back-to-back short ones.
Pick something else if you garden outdoors in Canada, if your space is short, or if you prefer a gentler, more grounded effect than a fast pure sativa delivers. Gelonade gives a similar citrus lift in a far shorter and more manageable plant.
How Amnesia Haze compares
Amnesia is the shorter-flowering relative and the more practical choice for most rooms. Super Silver Haze shares the haze backbone with more skunk and a slightly faster finish. Strawberry Cough is the gentler daytime sativa for growers who find this one too sharp. Among our sativa feminized seeds, Amnesia Haze is the yield leader, and our fastest flowering seeds guide is the place to look if this flowering time is the dealbreaker.
Frequently asked questions about Amnesia Haze
Is Amnesia Haze indica or sativa?
Amnesia Haze is sativa dominant, roughly 80% sativa and 20% indica. It is a polyhybrid built from Haze and several landrace sativas including Thai, Jamaican, Hawaiian and Cambodian lines, with Afghani and South Asian indica added to control the plant’s size. Both the growth habit and the fast, cerebral effect are sativa in character.
How long does Amnesia Haze take to flower?
Amnesia Haze flowers in 10 to 12 weeks, or 70 to 84 days from the switch to 12/12, and some phenotypes push closer to 13. That is long even by haze standards, and it is the main reason the strain is grown indoors. The last two weeks are where the lemon flavour and the clarity of the effect develop, so an early cut wastes the wait.
How strong is Amnesia Haze?
Amnesia Haze tests between 20% and 24% THC with CBD under 0.5%. What people notice first is the speed rather than the number: the effect arrives in ten to fifteen minutes and is intensely mental, with very little body weight to balance it. A small dose and a twenty minute pause is the sensible approach with a sativa this quick.
Can I grow Amnesia Haze outdoors in Canada?
Not in an open garden. Its natural outdoor harvest falls in late October or November, well past the first frost everywhere in the country. A heated greenhouse with supplemental light on the BC coast or in southern Ontario can finish it, but for an outdoor Canadian season you want a strain that wraps up in September instead.
Why a 12 week strain is worth buying from a seed bank in your own country
A long-flowering plant only makes sense if the calendar is on your side, and adding three weeks of customs to a twelve week flower is how a January harvest happens. Amnesia Haze seeds from MJ Seeds Canada are already in Vancouver, BC. They ship in plain, unbranded packaging with a neutral return address and reach any Canadian address in 3 to 7 business days, with free shipping over $200 and a $30 tracked and insured option that includes one free reshipment if a parcel goes missing.
We have been packing and testing seeds in Vancouver since 2009, and every Amnesia Haze batch is checked for viability here before it goes into a pack. Germinate with the cup of water and paper towel method from our germination guide and the 80% germination guarantee covers you, which matters more than usual when a failed seed costs you a full three month cycle. Packs are 5, 10 and 25 seeds, every 10 and 25 pack is buy one get one free, and orders over $420 add 10 bonus seeds.
Interac e-Transfer, credit card, Bitcoin and cash are all accepted, and our Vancouver team is on the phone, email, WhatsApp and live chat seven days a week, including week eleven when you are staring at fresh white pistils and wondering whether the plant will ever finish.

Excellent growth rate , high germination rate close to 100%. It grew strongly right from the beginning and flowered strong. Very nice and easy plant to grow and gets you good results. This is a very strong, hard hitting and long lasting smoke!
Toby Chabrillan –
One of the best strains I tried. Of all marijuana seeds, this one is very quick to grow. I had no problem from its day 1 up to its harvesting time. It produced huge buds! Thanks!
GGarcia –
Harvest was great and easy to grow. This plant offers a lot to look at the buds. The light green and coated dazzling buds at every glance. Sweet-smelling like Citrus, slightly creamy. Definitely a good smoke, but not as up-lifting as other haze varieties, so you won’t regret smoking before nap time.
Margaret –
Smell! This stuff almost makes my eyes water when I take a sniff. Incredibly pungent, intense hazy smell; tangy and sharp with zesty/chemicals(in a good way) undertones. The taste is similar, sour at first but with a sweet, full-bodied after taste The high is fast-acting and intense, incredible Sativa style uplifting effect and you can soon find yourself mental alertness due to the Sativa’s content. Great for getting some friends over and having a smoke, keeps you buzzing but allows for time to pass slowly and keeps you concentrating on what you are doing. Great hybrid, great taste, great high!

I just got my first batch of Amnesia Haze from Close Friends(Thanks Guys!!!) and I say Wow! I’m a big Sativa guy and this is in my top 5 now most definitely. Great Pungent, Lemon scent. Nice Compact, Dense Budz. Upon smoking, unbelievable, very easy and light to smoke can take big pulls & no coughing gives you a great boost of energy and alertness with a nice relaxing body feeling. Gives me the energy to start my day and during work and it just melts the stress & anxiety away. Always puts a smile on my face. A Holy Smokes!

Another exceptional season here in Michigan thanks to MJSC. I decided to try something new this year and went with a mixed pack of Amnesia haze, Chocolope, and Big Bud. Could not possibly be happier with the results. The Amnesia Haze is exactly as described. A very tasty, clean euphoric, and uplifting, one of the best I have grown in many years of experience. Between it and Chocolope, I truly can’t decide which is better and plan on growing both these strains next year. The outdoor yield was great, actually better than expected. Thanks for another great crop for three years running. Be advised Amnesia Haze is POTENT!

Overall my experience was ok. I lost all of my plants except one to **** spraying in my area. I managed to nurse one of the plants back to maturity and was rewarded with an excellent product, just not very much of it. I want to re-order seeds for this year and hopefully, I can buy it when there’s a promo sale. That’s what I like about this mjseedscanada.ca website they keep us! I can see an equal benefit on both sides haha. I highly recommend the Amnesia Haze plant. Enjoy every puff of this weed! A great strain.

I was expecting these girls to be challenging to grow and had zero problems indoors. I had one runt out of seven plants that just remained about six inches tall when it was time to flower. A couple of weeks after the new schedule, she went nuts and ended up being as tall as the tallest plant with the most robust and beautiful foliage of any plant I’ve ever grown!! The yield was phenomenal with the plants exposed to the most concentrated light producing the most. The flowers are still curing, but I’ve made carts from the trim and nugs… holy smokes!!! She’s a super heavy hitter and monumentally great tasting with that awesome lingering lemon scent. Wow. Can’t wait to taste the flowers! And MJSC is always remarkable to do business with. First-class all the way. Thanks, guys!

As a 1st time buyer, I only ordered 5 seeds. They were intercepted and MJSC.ca quickly replaced them. I only planted one and it sprouted easily. I used the wet paper towel method and planted the seed and the piece of the towel into a mix of worm castings, steer manure, and potting soil into an eighteen-gallon Walmart plastic barrel. The seed was planted on 7/20 and now it is 11/4 and the plant has thrived in the hot SW US weather. The buds are fantastic and smell wonderful. I clipped off a few pieces of bud, dried them out and the verdict is in. Wonderful product and I will be ordering again!

I just wanted to thank you for sending me a new order after the disastrous beginning that I had earlier. The seeds that I planted germinated within three days, which is what I usually see in most seeds. The most remarkable thing that I have noticed was that the Gold Leaf plants that I have growing have overtaken the plants that were in the ground three weeks prior! The tropical weather that we have been having here has been a blessing for these plants. By contrast, the Amnesia Haze plants have been growing much slower, but they are doing just fine, and are now about one foot tall. Even at this stage the smell really spicey. Can’t wait until October! and I certifiably am impressed with the results I’m getting so far. Thank You once again!

Paid for 3. Now, these beans are specific. Before the 20-day mark looks like wing spans I’m not easily impressed with the tiny tiny packaging but it did get here correct ., and on time. I have enjoyed nurturing these already in there really doing well. I love the site the info please sale sell one seed at a time, not a huge budget, and loves varieties with many thanks. If you buy multi-packs plant them before you lose them or misplaced them. It’s interesting the crosses mines got with amnesia haze fem. It’s 5 stars!

All ten germinated, 8 within 24hours, 2 within 72. Very healthy, under 16hours of light., in very rich potting soil, ladies are loving life. One went outdoors, native soil is taking off like a champ in Hawaiian light, one-month-old and beautiful branching, very consistent, can’t wait to try some Maui Wowie. The order took 6 business from payment to delivery. I am very happy, the gold leaf will be next, only so much space in the grow room, Amnesia Haze is worth it. BTW, I have one mutant who has super wrinkled leaves, short and stubby, almost round, looks very odd, I’m hoping it will continue its leaf structure into flowering, which would make trimming a breeze. T- 30 days till lights go to flowering, hoping for a 100day total growth. And so far it looks like it will hit that no problem. Will I use Amnesia Haze again? Most definitely!

I had this strain as an edible once, let me tell you if you have never had this as an edible, get ready to enter literal paradise on earth. It feels like you are riding a high that transitions through all of the various parents that came to create this strain. I remember staring at the computer screen and there was this afterglow and I was at complete peace with the world and everyone/thing in it. the munchies, food will taste incredible like you never thought the food could taste, insatiable hunger. and the orgasms. well. you will have to try it yourself and find out. Must TRY!
Grant –
It’s awesome great strain! A true mind fuck though, when I smoked it I was with one of my mates and his friend came along and thought it would be funny to “mind fuck” me. He’s a prick and that’s all that needs to be said about him. But a great strain, it gives you an amazing buzz, but it did make me paranoid after a while, a lot more than other strains I have tried. But it just mainly made me feel like I was In a dream, I had a few mild hallucinations, I was giggly and it’s an overall I love it!
Christopher –
This is one of my favorite strains of all time. I was looking through a small local store and saw that this was advertised as a “strong Sativa dominant hybrid that is floaty, cerebral, euphoric, creative”, and was supposed to taste like lemon citrus, all of these things advertised were exactly right and it was the best I ever spent. It was frosted with trichomes, smelled almost like fruity pebbles, with lemon, plus a little more citrus taste when smoked. Delicious, and exactly my kind of high. I wish we had more of this around the US legally. It’s a knockout!
Barbara –
It is a bud that pulls you by your bootstraps and forces your smile up to your forehead. Now though this may or may not be an exaggeration, it does what is promised well. This strain is a dark green trichome dynasty wrapped in bold orange hairs. Amnesia Haze brings on inner warmth/happiness while a calm euphoric buzz brings focus and creative sparks. I had vaporized this in flower and I almost got a cantaloupe sort of taste throughout the session. This strain would be one for people wanting that Sativa boost without the crash and burn. The couches call is no longer one you have to answer. Those who suffer from depression, chronic migraines, or have trouble eating, get your hands on this now!
Patrick –
Amnesia Haze smoked with tobacco The trip: I have the feeling my head floats and while listening to good trance music, it’s hella intense, just epic awesomeness. I hear my cats purring and when drinking I can feel the liquid go down into my stomach all the way. On antidepressants and neuroleptics, you can’t feel euphoria, but still, I’m smiling the whole time. I also feel very relaxed and could just drift away. But then there is so much which is interesting. Now it’s time for a cheeseburger 🙂 This gives you munchies. I will recommend this to all my friends!
Cynthia –
It’s a perfect morning strain. I’m not normally one for Sativas because they tend to make me too up and anxious but I like Amnesia Haze a lot. I get the right amount of energy. One bowl (about 20 hits) makes me feel clear-headed, energetic, motivated, and happy but I’m still relaxed. Another bowl of the same size makes my head feel lightheaded but not dizzy and increases the effects I already felt. I’m a full-time student and this strain helps me do my homework, which is often daunting. This is a creeper so be careful when you first smoke it. It took about ten to 15 minutes to feel the full effects. I would easily buy this again!
