Big Bud

  • Overview

  • Taste & Smell
  • Genetics

The name says it all, ‘Big Bud’ is quite simply one of the best-known high yielding strains in the world and rightly so. It was originally produced in the US, before being brought to the Netherlands in the early 80’s to evade the war on drugs that Nixon waged across America at the time. In the Netherlands, the strain was further stabilised and eventually went on to take the cannabis industry by storm by winning 1st prize in the Mostly Indica category of the High Times Cannabis Cup in 1989. Big Buds success comes from a simple idea that the breeders had, and that was to develop a strain with one goal in mind, to yield the most bud possible on a single plant. 

Since it was brought to the forefront of the cannabis industry Big Bud has grown to become one of the most popular strains in the world and even today it is hard to find another strain that can rival the huge yields that it can produce. 

Training techniques: Performs well with all training techniques, however because Big Bud is a very dense, bushy plant it suits LST & ScrOG most because you're able to easily manipulate the shape of the plant, creating plenty of opportunities for new bud sites as she grows - Read more on how to train your cannabis plants

Big Bud is renowned for producing not only huge buds but also dense tightly packed ones with very few leaves which is why the strain has become synonymous among cash croppers and alike. As the name suggests Big Bud is an incredibly high yielding strain which is why it sits at the top of our biggest yielding strains of 2021 list. Growers will enjoy a plentiful supply of big juicy cannabis buds, the only real down side to cultivating Big Bud is having enough room to grow it!

Big Bud is a 60:40 Indica dominant hybrid that grows to around 180cm tall, the plant is a vibrant green colour clustered with orange hairs and once the plant is in flowering it will develop solid sticky buds that cover the branches from top to bottom. Some growers use supports for the branches as it has been known that the branches can bend and snap under the weight of the buds if they are not thick enough at the time of flowering. 

Big Bud has a typical Indica high with a heavy full body stone that comes on gradually. The strain is known to make you feel hazy and some users report it bringing on some psychedelic symptoms like mild visual distortions. It is definitely a strain that is suited to lazy activities, such as watching movies and relaxing at home.

The relaxing effects felt from the high of Big Bud have lots of medicinal benefits and it is often used to assist pain relief, stress, and arthritis. Its natural ability to slow you down and induce a lazy relaxed feeling means it is the perfect strain for anyone suffering with insomnia, the fact that it is only a medium THC strength means that you will ease into a long deep sleep and wake up feeling relaxed if a little groggy.

Because of the relaxed drowsy high Big Bud is not recommended for anyone that is looking for active social highs or for use while doing anything that requires any degree of concentration.

The smell of the buds is pungent with a sweet earthy aroma with a hint of citrus. Big Bud is a smooth smoke with a sweet taste and hint of spice and earthiness, you will also notice fruity undertones that can taste similar to grape.

Originally developed in the United States Big Bud is a 60:40 Indica dominant hybrid mix of three high yielding parent strains; Afghani, Northern Lights and Haze.

Gorilla Glue

  • Overview
  • Appearance
  • Effect
  • Taste & Smell
  • Genetics

Otherwise known as GG#4, Gorilla Glue being up to 32 percent THC is typically only normally listed in the high THC strains categories, however this strain has more strings to its bow than that. Other than being incredibly potent Gorilla Glue can yield up to 600 grams per square meter which for a strain that will quite literally knock your socks off is impressive. 

Gorilla Glue was aptly named after the famous Glue Brand because the strains were so sticky that when you trimmed the plant it was as though you had literally glued your scissors together. 

Gorilla Glue in the cannabis world is a relatively new strain and since its introduction it has won numerous awards including the 2014 and 2015 Cannabis Cup for Best Cross Breed category, where it was famously describes as ‘a bunch of trichromes with a few buds, leaves, and stalks sticking out’. If you are after a cannabis strain that is both high yielding and super high THC then look no further.

Training techniques: Well with most plant training techniques, a trick that works will with Gorilla Glue to produce bigger yields and even higher THC is Supercropping, this is because the stress inflicted on the plant often causes the plant to increase nutrient uptake and increase trichome production. Gorilla Glue being a trichome rich plant works wonders with Supercropping. Read more on how to train your cannabis plants

Gorilla Glue #4 is a 50:50 indica/sativa hybrid, on average the plant grows to around 200cm tall and has a dense foliage of dark green leaves spattered with white crystals.

Gorilla Glue is a rare breed of cannabis, it wont quite compete with the likes of Big Bud and Incredible Bulk on size, but it knocks it out of the park when it comes to THC levels. Gorilla Glue has been known to have THC levels of up to 32% and for a plant that is also high yielding there will be a lot of good quality weed there to get you stoned. Gorilla Glue makes it onto our list of the best big yielding strains not because it is the biggest yielding plant, but to have a strain that is high THC and also produce yields of up to 600 grams per square meter is impressive.

An 80:20 Indica dominant Super Skunk is famous for its intense skunk flavours and its full body Indica high. Super Skunk was the creation of Sensi Seeds and first came to fruition from their hybrid breeding project that aimed to improve upon existing strains with Afghani roots such as Skunk #1 and Shiva Skunk with the aim to perfect the Afghani genotype and create the perfect strain, and we think Super Skunk came pretty close. 

Super Skunk is a near perfect strain for cash croppers because it achieves three of the most important attributes of a cannabis plant; high yielding, high THC percentages & fast flowering times and it even contains a decent amount of CBD. It is very rare that you come across the holy grail of strains that achieves all three but I think Super Skunk comes as close as you are likely to get.

Training techniques: Super Skunk is a very versatile strain and works well with most techniques however, as it is a short indica it works best with SOG where you can pack lots of plants into a smaller area and really use your grow space efficiently to maximise yields.

Thanks to its Indica genetics the plant grows out wide and will have a dense foliage of leaves with clusters of enormous trichome smothered buds spreading across the plant. Its branches naturally grow thicker than the average plant however it is advisable to support some of the heavier bud laden branches to prevent them from snapping under their own weight.
