Top 10 High THC Strains

THC is the main psychoactive cannabinoid in marijuana and its effects are what make the marijuana plant so popular. Whether you like the strong, relaxing, couch-locked indica effect or the euphoric, giggly high of a sativa, the THC content of a strain plays a major role in choosing it.

High THC strains can also be of great benefit to medical users. THC is responsible for a majority of the plants medicinal properties, including helping users deal with pain, anxiety, stress and insomnia. Consuming strains higher in THC means that those wanting the medicinal benefits will only need to consume a small dose to feel its effects compared to those lower THC strains, which is always a plus.

Here is a round-up of our top 10 high-THC strains.

 

Gorilla Bomb by Bomb Seeds

Sativa-dominant Gorilla Bomb is a cross between Gorilla Glue#4 and THC Bomb. It has average THC of 25+%.

The initial effect is a joyous rush of energy, which is also surprisingly relaxing. Over time, however, this mellows and you will almost certainly experience some degree of couch-lock.

In terms of flavour, it's a mixture of chocolate (both sweet and bitter) and diesel. You might not taste much at first but give it a bit of time and you definitely will.

Gorilla Bomb is fairly compact (0.9M to 1.3M), which makes it a good choice for indoor growing (9-10 weeks). It does have a very big appetite in the later stages of vegetation and flowering, but then it also produces very respectable yields (400-550g/m²). Gorilla Bomb can also be grown outdoors, although the October harvest might be a bit late for a lot of people.

Big Bruce by Mega Buds

Sativa-dominant Big Bruce is a cross between Bruce Banner #3 and Critical Kush. It has average THC of 27+%.

This strain really does pack a punch. At first, you’ll feel full of energy and creativity, then all you’ll want to do is lie on your couch and chill.

In terms of flavour, this is Kush meets diesel and it’s a really strong mouthful, so make sure you’re up for it (or use it in edibles).

Big Bruce is on the higher side of medium height. It can easily reach 1.8M indoors and more outdoors. The indoor flowering period is 8-10 weeks and the outdoor harvest is early October. This strain has a hearty appetite, but feed it well and you can get yields of 500-650 g/m2     .

Mimosa Evo by Barney’s Farm

Sativa-dominant Mimosa Evo is a cross between Purple Punch and Clementine. It has average THC of 24+%.

This is actually quite a slow-acting strain, but once it gets going you can expect regular bursts of clear, motivational energy which will still leave you reasonably functional.

In terms of flavour, this is a strain for people who like it fruity. Your first impression may be that this strain is pure lemon citrus, but wait a little and you’ll find there are plenty of berries in there as well.

Mimosa Evo can easily reach 2M+ indoors, although training can keep this down. Outdoors you can take it as read that it will reach at least 2.2M. The indoor flowering period is 9-10 weeks and the outdoor harvest is late October. Yields are amazing, you can get 700 g/m² indoors and 2Kg per plant outdoors.

Grandaddy Banner by Big Head Seeds

Indica-dominant Grandaddy Banner is a cross between Grandaddy Purple and Bruce Banner. It has average THC of 24-28%.

The head high is exactly what you would expect from a quality Sativa. It’s energetic, euphoric and sociable. You’ll be happy to chat to anyone who’s around. Afterwards, however, this will mellow into the classic Indica body-stone.

In terms of taste, this strain starts off as being full of robust, sweet earth and then rounds out to creamy vanilla and florals.

Grandaddy Banner is on the shorter side. It’ll usually reach about 1.6M indoors, maybe a bit more outdoors. The indoor flowering period is 8-9 weeks and the outdoor harvest is early October. This is a greedy strain, but you can get yields of up to 600 g/m² indoors and 600g per plant outdoors.

Sugar Breath by Humboldt Seed Organization

Indica-dominant Sugar Breath is a cross between Do-Si-Dos and OGKB. It has average THC of 26%.

In terms of taste, this strain is actually grape-sweet rather than sugar-sweet. This is balanced by fuel and there are also hints of pine, incense, vanilla and cinnamon.

Indoors Sugar Breath tends to stay relatively short and bushy, 1.2M to 1.6M would be a reasonable expectation. Outdoors, however, it can easily reach 3-4M. The indoor flowering period is 9-10 weeks and expected yield is 400-600 g/m2. The outdoor harvest is mid-October and you can collect up to 3Kg per plant.

Wedding Drake – Dragon Seeds

Indica-dominant Wedding Drake is a cross between OG Kush, Durban Poison and Grand Daddy Purple. It has average THC of 25%.

The effect of Wedding Drake initially, very energetic although in a mellow and chilled way. This then transitions into the classic Indica body stone.

In terms of taste, Wedding Drake tastes more like a vanilla pastry than a cake although there are also hints of earth.

Indoors Wedding Drake is medium-tall, 1.5M to 1.8M would be a reasonable expectation. Outdoors it can push a bit higher. The indoor flowering period is 9-10 weeks and expected yield is up to 600g/m2. The outdoor harvest is around the end of October and you can get yields up to 800g per plant.

Girl Scout Cookies – Auto Seeds

Sativa-dominant Girl Scout Cookies is a cross between the original GSC and MiG 29. It has average THC of 24%.

The initial effect is cerebral and euphoric. This then mellows into deep relaxation, but won’t leave you couch-locked.

In terms of taste, this is very much classic cookies with plenty of brown sugar, chocolate and nutmeg edged with pepper, lemongrass and a hint of pungency.

GSC can be grown indoors or outdoors. Either way, you’re looking at a height of 0.65M to 1M and a grow time of 10-11 weeks. A typical yield is around 450g/m2 although experienced growers can push this up, especially if they use Sea of Green.

Gelato Auto – Fast Buds

Sativa-dominant Gelato Auto is based on classic Gelato. It has THC of up to 26%. This strain has become popular because its high is creative and sociable as well as uplifting and energetic. In terms of flavour, this is more cookies than cream, although there is a smooth roundness to it.

Gelato Auto can be grown indoors or outdoors. Either way you’re looking at a height of 0.7M to 1M and a grow time of about 9 weeks with an expected yield of up to 500g/m2 or 300g per plant.

Cookies Haze – Kannabia

Sativa-dominant Cookies Haze is a cross between Afghan and Super Silver Haze. It has average THC of 25%.

The effect is a euphoric, happy buzz, which transitions into a very light body buzz. You stay fairly functional, in fact, if you’re a creative then this may help you to get some work done.

Despite the name, this strain is fruity sweet rather than candy-sweet and there’s a citrus edge to keep everything fresh.
