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. Green Crack Auto 24-35 inches 

Who wants to get hyped! No strain provides a rush like Green Crack (sometimes called Green Crush). The original version of this legendary strain comes in both Sativa-dominant and Indica-dominant varieties. Fast Buds' Autoflowering version is an almost perfect 50/50 hybrid that gives the rush of a Sativa, while the Indica relaxation eliminates paranoia and nervousness.

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.

Grow Tips

  • 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.
