Top 7 Marijuana Strains to Grow in 2021

Published on 2/16/21

It seemed like it would never end, but 2020 is finally in the rearview mirror. For growing marijuana at a commercial and small-scale, the new year means a new set of strains for the upcoming cannabis cultivation season

With so many indicas, sativas, hybrids and high-CBD varieties available from local dispensaries and online seedbanks, it can be hard to narrow your choices and select the best weed strains for your garden or grow room. Thankfully, we've looked high and low to find you the most potent, flavorful and popular strains of weed to put in the ground and help you get through whatever 2021 has in store.

How to Grow Weed and Buy Cannabis Seeds

Before you pick out your list of strains for the 2021 season, it is important to know how you'll be growing cannabis and where you'll be buying your seeds or clones. 

First, pick where and how you'll be planting your cannabis. If you live on the west coast and you've got some space, consider cultivating sun-soaked outdoor crops. If you don't have the room to grow outdoors or you live in a colder state in the Midwest or East Coast, pick out a grow tent or lighting set-up that will fit your basement, closet or warehouse grow room. Next, do some research and decide whether to use living soil or a hydroponic system. Once you've made your decisions on how to grow marijuana and bought all the correct marijuana growing supplies you need; then finally, you can start thinking about strains.

If you're looking for the least amount of hassle, search local dispensaries for clones. These early-growth plants already developed roots and will be easy to transfer into your grow station. However, if you can't find clones of the strains you want, it's time to look for seeds. Like flower, vape carts and dabs, cannabis seeds are still subject to federal prohibition. Luckily, most dispensaries in legal weed states that allow home grow also sell seeds. Additionally, many online seed banks label cannabis seeds for "novelty purposes only" and sell them on the internet. Unless the seed bank's location is in your legal weed state, ordering seeds online is still technically illegal in the eyes of the federal government. Keep in mind, growing some strains requires a bit more cultivation skill than others.

Cannabis strains named after sweets have been a dominant force in the marijuana market for more than half a decade now. The pastry obsession is still strong, and for good reason. a cross between Gelato 25 and South Florida OG, Biscotti is a potent flower that smells of vanilla cream and fresh cookies. The terpene-heavy indica-dominant hybrid is a moderate yielding plant that will stink up any grow tent or home garden.

Chili Verde

If you're adding a few cannabis plants to your vegetable garden, Chili Verde is a perfect strain to add next to your favorite peppers. The high-yielding strain is a great choice for growing your own marijuana, has a flowering time of 9 weeks and responds well to trellising. During harvest season, the massive buds will smell of pepper and lavender and offer a focused, head-focused sativa high. Chili Verde will keep you going all day, but with THC percentages pushing above 20%, it also offers psychoactive effects that satisfy even the most experienced stoners.

Chocolate Tonic CBD

Sometimes, THC should take the background while CBD shines. If you're looking for a strain with a solid ratio of your favorite two cannabinoids, try Chocolate Tonic CBD. The cross between Cannatonic and Chocolate Kush is an even hybrid with a 2:1 CBD-to-THC ratio and gorgeous green buds. The strong yielding plant grows well indoors, outdoors and in a greenhouse, making it an ideal medicinal choice for any sized garden.

Ice Cream Cake

Ice Cream Cake took off as one of the most popular strains on the market in 2020, and that status isn't dying down anytime soon. The indica-dominant strain performs best indoors or in a greenhouse, but will also yield moderately well outside. The sweet, cakey buds are incredibly potent but will take about 9 weeks of flowering to fully mature. Like most facets of life though, the best things are worth the wait.

White Runtz

Another dispensary best-seller in 2020, White Runtz will finally make its way from long-lined limited-edition releases to home gardens in 2021. Beloved for its incredibly fruity terpene profile and coating of trichomes, White Runtz will be a standout in any cultivation site. The Gelato x Zkittlez cross usually tests at about 25% THC and grows best under regulated conditions indoors or in greenhouses. 


Sweeties is a relatively new strain on the scene, but the candy-like hybrid will be making waves on dispensary shelves and home-grow gardens in 2021. A cross between Face Off OG and a super-mix of The White, GSC and Tahoe OG, Sweeties may smell like sugar but also packs a punch, usually clocking in above 20% THC no matter where you grow it. Let Sweeties flower for 9 weeks for a quality yield on a top-shelf flower.

Banana Mango

An excellent strain for outdoor cultivators, Banana Mango is easy to grow and produces high yields of massive buds that reek of fresh fruit. This sativa is a cross between Mango Trees, Banana OG and Blueberry Muffin, making an incredible trifecta jam-packed with terpenes and a steady THC content in the high teens or low twenties. If you want a strain that will produce enough weed to smoke for the whole year and fill the room as soon as you open the jar, seek out Banana Mango seeds or clone as soon as possible.
