How to tell the difference between Sativa & Indica

Having trouble figuring out whether you’re smoking an indica or sativa? Here’s a handy little guide to help you figure it out. This post will tell you the easiest ways to differentiate between cannabis sativa and indica in both live plants and in dried bud. Enjoy!

Live plants

In live plants, differentiating between indicas and sativas is really quite easy. Once you know what to look for, you’ll be able to tell just from a quick glance. Here’s what you need to know:


tivas are tall plants with super thin leaves. Sativas are a bit sparse and thin with wider spaces in between branches than their indica relatives. During their flowering phase, they quickly surpass indicas in height. If you notice that your plant starts to get super tall and bush out a little more during the flowering phase, you probably have a sativa.

When grown under perfect growing conditions outdoors, sativas have been known to reach heights of up to 20 feet. Pretty crazy, right?

To summarize, sativa plants:

  • Are tall
  • Feature super thin leaves
  • Are less dense, a little sparse
  • Have exponential vegetative growth during flowering

Indicas are short, stocky plants native to colder climates. A surefire sign of an indica is the presence of fat fan leaves, where each leaf segment nearly touches each other or even overlaps a little. Sativa leaves look more like thin little fingers in comparison to indica leaves. While sativas can nearly resemble a tree under the right conditions, indicas are more like a squatty bush.
They tend to have dense branches and hover around four feet tall. That’s a pretty big difference when compared to sativa relatives. While sativas nearly triple in size during flowering phase, indicas often increase their vegetative growth by about 100%.

To summarize, indica plants:

  • Are short
  • Feature fat, broad leaves
  • Are quite dense, squatty
  • Double, rather than triple in size during flowering

If a female plant is kept in the vegetative stage long enough (the length of time varies depending on the strain and conditions), then she will start showing the first sign of female hairs even before you move the plant into the flowering stage by changing the light schedule.

If you see wispy white hairs appearing on your plant like the ones pictured below, then you know you have a female plant.

This pre-flower doesn’t have a pistil sticking out at first, but the shape helps tell you it’s a female plant. If you’re not sure about gender after spotting a pre-flower, it’s a good idea to wait and see for a little while, just to see if a white hair appears (which means it’s definitely a girl)


Sativa Buds:

Sativa buds are longer, thinner, with bud particles that almost look like wispy hairs. Though, while the bud itself may look larger than those from an indica plant, they tend to be a bit lighter when you actually weigh them out. This is because sativa flowers are not as tightly compact as indica flowers.

When sativas bloom, the flower forms along the branch, almost like it’s a bit stretched out. This lends to the wispy, hairy nature of their buds.

Deep red or orange coloring is also a sign of a sativa. Sativas tend to grow in warmer climates, and they often express deep reddish or strong orange phenotypes. Sativas also tend to put off less of a strong, pungent fragrance. You’re more likely to find fruity, tropical aromas in sativas.

To summarize, sativa buds are:

  • Long
  • Less dense
  • “Wispy” bud, fluffy
  • Often feature red or orange coloring
  • Have a sweeter or lighter aroma

Differentiating between sativas and indicas in dried bud can be a little more difficult, especially with all of the hybrids out there. Once you know the basic features of each type, however, you can make an educated guess as to whether or not your strain is indica or sativa dominant.

Indica Buds:

Indica buds are more compact, shorter, and extremely dense. When indicas flower, their blossoms tends to stick closer to nodes along the stem. Nodes are present where new branches and the main stem meet. This lends to their short, squatty, and heavy buds.
Another thing to keep an eye out for is any purple coloring in the plant. Since indicas are native to cooler climates, they’re more likely to express purple coloration. The big purple strains are all indica dominant, but sativas will develop some purple if they’re grown in cool climates as well.

Perhaps as a survival mechanism for cooler climates, indicas tend to be more THC heavy. They also tend to produce a very thick, pungent aroma.

To summarize, indica buds are:

  • Short
  • Heavy
  • Compact and dense
  • Often feature purple coloring
  • Have a thick, pungent aroma

These are just some quick tips to help you better identify what you’ve got. As mentioned above, with all of the hybrids out there, it can be a little tricky to determine whether you have indica or sativa dominant strains.

Many modern strains now have a good mix of both types, creating truly unique smoking/vaping experiences. If you want to get a taste of what true indicas or sativas are like, ask a local dispensary if they have any landrace or pure indica/ sativa strains.
