New Genetic Marijuana Strains for 2021

With every new year arrives new opportunities, new chances at life, new resolutions, new plans and goals, and most of all, new cannabis strains.

Luckily, events like the Emerald Cup are a perfect opportunity for industry professionals to check out the best of the best for each new year. Keep your eyes peeled for these strains throughout 2021; soon your local dispensaries are going to be lining their shelves with some of these magnificent genetic masterpieces.

1. Wedding Crasher (Hybrid) – The Strain that Tastes Like Wedding Cake

A new cultivar from one of our favorites, Symbiotic Genetics, the same breeders that produced one of last year’s top contenders, Mimosa, Wedding Crasher is the main cannabis strain that S.G. has been marketing and releasing to the public, but there is a strong reason why. No, unfortunately these buds won’t zap you with the courage to jump into the wedding reception of some strangers and eat all their free food and drink all their open-bar booze, but this strain is capable of doing things much more valuable in our opinion.

Wedding Crasher has a way of calming down the mind . Its high is very heady and all consuming, leaving its lucky consumer with a peaceful, tranquil, and clear mental state that can last throughout the entire duration of the strain’s effects. The high from Wedding Crasher is known for being rather arousing and talkative, so maybe these characteristics do mimic what could possibly happen at a wedding, but beyond that this is also a very medicinal marijuana type. Additionally, Wedding Crasher could cause you to feel tingly and uplifted, with an increased desire to be creative. Medically speaking, this strain is known to soothe cramps, muscle spasms, inflammation, and fatigue, as well as resolve any depressing moods, feelings, or sensations.

Finally, what truly is the icing on the cake, is the flavor of Wedding Crasher, which resembles that of a vanilla wedding cake, blended with hints of grape, which makes for a smooth, sweet, and even sometimes grassy strain, that has a pleasant berry finish . Wedding Crasher is a genetic masterpiece produced by crossing Wedding Cake with Purple Punch.

2. Sour Berry Blue (Sativa) – The Floaty Tropic Strain

One of the more recent releases from Colorado based The Farm Genetics, Sour Berry Blue is a sativa dominant strain that was made by crossing over the High Times Cannabis Cup winner Alpha Blue with Sour Strawberry. Known to be one of the strongest Sour Strawberry crosses, Sour Berry Blue is honestly no joke, with its flavor and aroma profile which is somehow oddly reminiscent of a floaty tropical paradise. Tasting like a tropical fruit cocktail, with hints of sugar and berry, this strain is essentially just a yummy, sugar berry delight, with a scent that is equally as delectable.

Unlike many sativas, the high from Sour Berry Blue is not so much energizing, more so it leaves its consumer with a body-numbing, euphoric sensation that is extremely uplifting and elevating. You’ll definitely feel as if you can kick back and truly relax with this one. The THC levels of Sour Berry Blue range between 20%-26.5% on average, so get ready to let your mind and body float off into the deep blue sea, only to end up on some tropical island paradise.

3. Tropicana Cookies (Sativa) – The Strain That Mixes Breakfast and Dessert Into One

Bred by Washington based seed developer Phat Panda, Tropicana Cookies is an interesting blend between Tangie, an ultra citrusy Dutch sativa, and Forum GSC. Said by many to smell strongly of orange juice, this sativa dominant strain carries many strong notes of tangerine and other citrus fruits, which is then balanced out by its dessert-like undertones, which are that of fresh baked cookies , leading to a smooth overall creation that is essentially breakfast and dessert combined into one smokeable, high-bringing entity.

Sounds pretty amazing right? Tropicana is known for creating an aroused and focused high, coupled along with plenty of happiness, giggling, and uplift. Medically speaking, this strain is best for managing depression when it comes to the mind. Physically, it can help with stress, eye pressure, cramps, and nausea. The buds of Tropicana Cookies are beautiful, carrying a distinct dark purple and dark green color, further accented by bright orange hairs; a true delight to grow yourself. Unfortunately, Tropicana Cookies might not be the easiest strain to find. It is sold by some partner companies, but dispensaries are only just beginning to know of its existence.

For this reason, it’s best to call your dispensary ahead of time and ask them if they stock this fruity delight. If you happen to reside in the Washington area, there is a more likely chance that you’ll be able to get your hands on this Tangie x GSC crossover.

4. Palm Tree CBD (Indica) – The Low-THC Strain of Your Dreams

A well-balanced THC : CBD strain produced by Snoop Dogg’s own cannabis company, Leafs by Snoop, Palm Tree CBD has been making some headwaves these days, and we are pretty certain we know why. With a 4-13% THC content and a 6-12% CBD content, this yummy ganja is known for its calming and medicinal effects.

Assisting with a wide array of medical conditions, including eye pressure, fatigue, stress, headaches, and inflammation, if you are generally a fan of low-THC marijuana strains, then you are bound to fall in love with Palm Tree CBD. This strain carries a strong citrus flavor, with elements of lemon, orange, and other citrus fruits. Known for its distinct looking buds which are lime green in color and especially dense, with hints of accentuating purple and fluorescent orange hairs, the minute this strain is in your presence, you’ll know. Its aroma is strong.

The effects of Palm Tree CBD are not only calming, but also relaxing, sleepy, and euphoric, much like many of your other traditional indicas . Furthermore, Palm Tree CBD can have a strong body high, which will leave you not only feeling happy and content, but also tingly all over.

5. Mint Chocolate Chip (Hybrid) – The Refreshing and Rejuvenating Strain

One of the most recent releases from ExoticGenetix, the industry has been freaking out over this entire seedline lately, with many delicious picks to choose from, all ultimately stemming from the stable genetics of Mint Chocolate Chip . This strain is the genetic crossing between the SinMint Cookies strain and Green Ribbon BX, Mint Chocolate Chip is actually the strange pairing of two opposing genetic lineages, which makes for quite an intriguing final product.

The initial flavor of this strain is earthy and diesel-like, which then is followed by a minty and creamy finish, which is honestly quite refreshing and rejuvenating. The buds of this strain are known for being packed with dense resin, which gives them their glossy, glittering appearance. Best consumed in smaller doses, the effects of Mint Chocolate Chip remain euphoric and relaxed, inducing happiness and creating mental energy, but when consumed in higher doses, this cannabis type has been known to make its consumer less functional.

If you don’t mind chilling on the couch all day and watching some Netflix, then higher doses are perfectly alright, but if you plan on getting something done, minimize your doses. Medically speaking, this weed type is best for managing depression, stress, headaches, inflammation, and pain. If you are a grower, you are in luck.

The easiest way to get a hold of this bud is to buy the seeds directly from ExoticGenetix, and cultivate your own Mint Chocolate Chip plants. It might still be a bit challenging to buy this marijuana in a dispensary, so cultivation will always be the easier option if you feel you are qualified to do so, or are willing to take on a bit of a challenge.
