Bigger is not always better. A supersized Sativa may look great in photos, but what do you do when it starts to outgrow its tent? Get a bigger tent? Well, then how do you discreetly place that in your home? Nobody wants law enforcement banging their door down because their pot plant was too big to hide.

If you value stealthiness or have limited space, autoflowering cannabis seeds grow compact and shorter, and can still provide you with big yields and potent flowers. Instead of growing like trees, these strains grow like squat bushes packed with dense buds. Sometimes referred to as dwarf cannabis, modern autoflowers offer staggering yields and award-winning, high-THC buds within 10-weeks of planting. With that in mind, let's kick off our list at number 5 strains!

For each strain, we've included a link to a grow report/grow diary that illustrates one way (of many) to successfully grow each variety. Check out our grow tips.

5. Afghan Kush Auto 24-35 inches 

Who wants to get hyped! No strain provides a powerful relaxing high like Afghan Kush Auto. The original version of this legendary strain is a super strong Indica variety and Fast Buds' Autoflowering version is an almost perfect version of the original, but with our twist, offering the Indica relaxation while eliminating paranoia and nervousness.

“... the taste was of green […] mango and after it cured for 3 weeks […] the fragrance turned to ripe [...] mango [...] It would first make you talk out, then euphoric and then totally relaxed...”


This strain produces light-green buds with a long, dense, and pointy appearance while being completely buried in a thick layer of resin that gives them that beautiful sticky aspect.


“I was looking for a strong old indica and found the Afghan Kush Auto. I grew her in a 40x40x120cm tent with a 150w led. She was fed with dry organic nutrients and a pk booster in flower. My goal was a micro grow with four plants in a small space, one of it was the Afghan Kush. So the pot size was very small 5 liter. The plant was short but the buds where so perfect. A lot of resin and trichomes. This strain is very strong and will help with pain. You get super relaxed and sleepy with hard munchies. Typical Afgahn Indica. (I would say 100% Indica!).The Smell was Earthy and Spicy. Super easy to grow and perfect for Indica lovers.”

Grow Tips

  • Due to growing homogeneously, it’s ideal to maximize your grow space by cultivating in a SOG.
  • Doesn’t matter if it’s indoors or outdoors, this plant likes a lot of nutrients so make sure you feed her properly.
  • Remember to tie down the branches or perform other LST techniques to make sure the buds get enough light and fatten up properly.

4. Blueberry Auto 24-43 inches

Bred with indoor stealth grows in mind, our Blueberry is dorm-room closet ganja par excellence. Reaching a modest 24-43 inches, or 110 centimeters, this strain offers a fruity, wild berry-rich aroma, unlike any strain you've tried before.
