What Makes The Best Weed Strains of All Time

If you’re looking for the best strains of all time, then there are several elements to consider, and we’ll share them in this section.

First of all, you should look at the terpene levels within the strain. You’ll want them to be as high as possible. Alongside this, you should want it to have a potent scent and flavor, which will be influenced by the flavonoids in the strain. 

A good way to test whether a strain is one of the best weed strains of all time is to roll some into a joint and try it dry. Then, smoke it and see whether the taste and smell are consistent. If it is, then you’re dealing with a great strain. You can also factor in what other growers and smokers have to say about the strain. 

If you want to look at the strain in more detail before making a decision, then you should check the composition of the cannabinoids in the strain. You’ll want to make sure THC levels are as high as possible, and that the terpenes are complementary. 

Once you’ve considered all these elements, it’s safe to say you’ll have a great strain, and it may even be one of the best. As for us, we’ve found six that we think are the best cannabis strains of all time.

Maui Wowie Strain

Maui Wowie is an 80% sativa strain, with up to 20% THC levels. This is a decent amount, and it’s easy to grow the strain too. That’s what got it entered into our list. It also stands out for its delicious scent and the positive effects it can have on your energy levels. It comes from Hawaii, and it reduces your stress too. Some say it came into prominence in the 1960s after hippies discovered it.

In terms of climate, it’s best to plant it indoors in a temperate environment. This is something that you can recreate easily inside a grow room. You should make sure that it has a light breeze and has soil that’s rich in nutrients. But bear in mind that the plants will grow tall. It’s worth it because you’ll be getting a good yield of 14-17 ounces for every plant.

OG Kush Strain

OG Kush is one of the best cannabis strains of all time because it’s been popular all over the world for a long time. It’s derived from a strain called Chemdawg, but others say it comes from the Hindu Kush strain. 

It’s 75% indica and 25% sativa. THC levels are a little on the low side, at up to 19%. It’s not quite as easy to grow as Maui Wowie, but not difficult either. The best climate for this strain is Mediterranean or Continental one simulated using a grow room. 

It will yield 16-17 ounces, which is a decent amount, and it has a range of positive effects. These include inducing euphoria, happiness, and relaxation. You’ll be able to identify it by taste or smell too. You’ll notice lemony, spicy, piney, and earthy elements when smoking it. 

It makes a great choice if you’re hyperactive and needs a way to calm down. That’s because the indica and sativa combine to help your mind and body.

Gelato Strain

If you want to smoke some marijuana that hits you hard, then there is no better option than Gelato. It’s almost perfectly balanced between indica and sativa, with a slight bias in favor of indica at 55%. THC levels are up to 20%, which is fair. It came from California when two other strains were bred together. These were the Thin Mint GSC and Sunset Sherbert. 

The plant requires a Temperate or Mediterranean climate to grow and is best grown indoors. It’s small when grown, so if you’re limited in space this strain is ideal. However, it does take longer to flower than the others, with an average of 10 weeks. 

Its yield is fair at 16-18 ounces per plant, and it tastes of fruits. In particular, you’ll notice citrusy flavors and hints of sweetness. The strain will chill you out and lift your mood, so it’s helpful if you’re feeling low.

Zkittlez Strain

Despite the odd name, this is a strain you definitely shouldn’t ignore. It tastes like candy, so if you have a sweet tooth then it will probably become a firm favorite of yours. It’s 70% indica and 30% sativa, with a THC level of up to 23%. It’s got a higher THC level than the other strains we’ve reviewed, so it’s not only sweet but intense too. It comes from a combination of Grape Ape and Grapefruit. 

It grows to an average size, takes 8 weeks to flower, and doesn’t take too much maintenance to grow. When harvesting, you’ll get between 16-21 ounces for each plant, which is a great amount. It will grow best in a Temperate or Mediterranean climate, and it’s also got the added benefit of being mold-resistant.

When smoking it, the two main flavors and scents are fruit and pepper. It will make you feel euphoric and happy, but sleepy as well. So it’s a good choice if you’re trying to have a restful night.

AK-47 Strain

If your priority is relaxation, but you don’t want to zone out, this is one of the best weed strains of all time. It gives you a high that lasts for a long time and leaves you feeling aware and alert so you can get tasks done. It was created in the Netherlands by Serious Seeds over 25 years ago.

It’s a sativa-dominant strain, with 65% sativa and 35% indica. THC levels reach up to 20%, which is a fair amount, but lower than the Zkittlez strain. The climate you should grow this strain in is Mediterranean, and you’ll need to keep in mind that it can grow quite tall. The strain tastes pungent, sweet, and sour all at the same time. 

It takes 8 weeks to flower, which is on the faster side, but you’ll only get a yield of 14 ounces per plant. So you’ll have to plant quite a few to get a good harvest overall. However, it has won awards, like the Cannabis Cup, so you’ll be getting great quality.

Super Silver Haze Strain

This is another well-known marijuana strain, and it’s on our list as one of the best cannabis strains of all time. It’s almost entirely sativa, at 90%, but THC levels are a little low at 18%. It’s also not as easy to grow as some other strains, because of its height. However, it does resist mold, so that’s one concern you won’t have.

It will take around 9 weeks to flower, and you’ll get a sizeable yield of 19 ounces for each plant that you grow. Its effects are worth noting too. It will increase your creativity while also making you feel uplifted and energized.

When you smoke it, you’ll smell and taste skunk and herbs, so if skunk is a flavor you’ve been looking for, then this is the right strain for you. The strain came about by combining three different strains – Northern Lights Indica, Skunk No.1 Hybrid, and Haze Sativa.
