Description

Pineapple Express Auto is one of the original Fast Buds strains, combining stable genetics, easy growth, and a bright tropical profile. This balanced sativa-indica hybrid reaches up to 20% THC and finishes in around 9–10 weeks.

Plants can stretch up to 140 cm, developing a vigorous Christmas tree-like shape with dense flowers forming along the main stem and branches. The buds are rich green, sticky, and covered in a thick layer of sparkling trichomes.

Sweet pineapple leads the aroma and flavor, joined by tropical fruit and subtle sour notes. The effect is uplifting and stimulating while remaining balanced, with enough relaxation to keep the experience comfortable. Its clear, energetic character works particularly well for creative activities and social settings.

Stable, sturdy, and straightforward to grow, Pineapple Express Auto is an accessible option for beginners while offering the production and flower quality experienced growers look for.

You changed my mind

One of the most beautiful phenos of any plant Ive grown. As a sativa and specifically land race specialist, It is quite nice to see Autoflowers which surprisingly hold very high sativa traits and finish in 55-80 days from start. 10 years ago I laughed at the notion of Autoflowers ever becoming worth anyones time. Im laughing again at the irony of my past statements. This sure beats 14-30 weeks of just flowering a Columbian or Thai. Hats off, guys and gals at FB. Great breeding work.

Buds

At the end of the grow, the buds were so massive that two actually broke off, so I had to tie up the rest. That’s never happened to me before. I don’t know what Fast Buds does to these plants, but these aren’t just cannabis plants anymore, they’re straight-up machines.

Resilient

I grew some pineapple express in Spain, outdoors using 15 litres pots. It took approximately 75 days. 10 litres pots are sufficient and recommend, temperatures were in some cases up to 35 degrees, on average, about 29 degrees. Humidty at night never below 80% and during they day ~65%. These buds god really hard and dense, and the weed is really strong. One of the strongest autos I ever grower.

Like a real pineapple.

Really pleasant fruity smell to this plant, very easy to grow not much attention needed. Really nice orange and deep green color with decent dense buds. The high is great from this strain, really uplifting energetic high for around 2 hours also very nice taste.<br>Would definitely recommend, and will be growing some more of this.

Pineapple Express

After 10 weeks it was finished. The plant has a very nice structure and branching. She grows incredibly fast because she knows how big she can get. The flowers are covered with resin coated and give off a fruity smell. The yield was enormous for one plant.

Customer questions & answers

Hey, what do you think about topping this variety at the 4th or 5th node? My indoor tent is small and I'm worried about the plant getting too tall. Thanks!

You can do it but we don't suggest toppings on autos. You may try to LST her carefully better.Thanks for asking! Enjoy it!

How many seed do I use per pot?

Hello, ideally you should only have 1 plant per pot but if you're using bigger pots (30L-50L) you may be able to grow more than one. You need approximately 11L per plant.

Hi! I will be growing 3 pineapple express plants outside this spring/ summer, do you have any tips? thank you!

Hello! As long as they're growing in a good environment with the proper amount of good-quaity nutrients they'll grow just fine.

Hi, what does everyone recommend for germination? Direct into soil? Soak in water glass? Paper towel method?

Hi! We recommend soaking them in water up to 48hs and after they start opening, place them in paper towel until you see the radicle coming out. You can also germinate them directly in the soil.

About know of an easy strain for a first time grower to get started?

Sure! G14, LSD-25, Pineapple Express, Rhino Ryder...Thanks for asking!

Hey! what strain have more potent and giggly effect this or mexican airlines (or another) Greetings =D

Wow, so different! Mexican is also a pretty nice trip to Cancun! :D Maybe PineappleExpress is more sensorial and MexicanAirlines is more straight.

Hi does pineapple express have any negative side effects such as paranoia or anxiety

Hello, thanks for asking. It's hard to say because it depends from person to person, please contact us via email or live chat and we will be able to help you better.

Pinnaple Express 10 weeks the whole circle or just flowering stage?

Hello, thanks for asking. That would be for the whole cycle, from seed to harvest.

Roughly how long of veg and how long of flower?

Hello, it should take around 5-6 weeks in veg and 5-6 in flower but it can vary slightly depending on your growing conditions.

Does anyone know the ideal soil PH for pineapple express?

Hi, Mike! Yes, 6,5 would be the optimal. Enjoy!

Hello, would be possible, with this specific autoflower, to stunt the height but still retain the yield using LED lighting in a 80/80/140cm area?

Yes, we suggest to to LST her. :)we hope it helps a bit!

Hi. Getting ready to grow the Pineapple Express (and a few other strains) in greenhouse. What size pots do you recommend?

Hi, thanks for getting in touch and for your trust!We suggest +20L pots, but you can grow them in any size. Up to you. :)Enjoy them!

I want to grow 4 five gallon pineapple express inside of a 32x32 x5 tent with 4 mars 300watt leds. With lst could i expect to get 300grams a plant?

Hi thanks fo asking! You can but maybe you lack a bit of light to get so. Enjoy it!

hello ive never grown an autoflower before in my life is this a good strain for a newbie grower and how well will pineapple express grow outdoors right in the ground

Hi Shawn! Thanks much for starting your auto-journey with us! :D Great strain!Yes, she'll be fine, give her enough direct light and watch the weather fluctuations. It's a great strain for outdoor and indoor. Keep us posted!

What is the max number of these you would grow in bubble buckets in a 4x3 tent with 630 watts of LED light? I am considering using LST as well...

Well, depends on your skills, Scott. Bear in mind this strain can get big. Maybe 4 would be ok. Thanks for asking!

Is this mold resistant? I think about growing it outdoors, I live in Göteborg, Sweden. Do you think I could succeed with this strain?

Hello! If the relative humidity is over 60% it would be better to grow strains like OG Kush, Gorilla Glue, and Rhino Ryder, among others. Please take a look at our catalog, we give that type of information under "grow tips".

How many days does it take for the plant to be harvest-ready? Living in Denmark, Europe and trying to figure out if it is too early to start. Cheers!

Hello, Jonas! Thanks for asking. Well, most of our strains take roughly the same time to grow. If you are after a high grade finished product all of our strains are going to take around 70 days give or take to fully mature. It can become very bushy! Cheers!

I heard pineapple express is quite resilient. Is ur autoversion good for begginers or would u recommend a different strain? (I want something really forgiving for mistakes).

Yes, it's a good strains for beginners but we have other strains like our Gorilla Glue Auto that are almost foolproof for newbies.
