The Six Best Frosty Weed Strains with Heavy Trichome Genetics

Whether you call it crystals, snow, sugar, or just the icing on the cake, there’s no denying that frosty weed strains are all the rage. With an increase in popularity, more growers are adding super frosty weed strains to their seed collections. It may not be the determining factor for grading top-notch pot, but it adds a little bling to your stash. Let’s look deeper into why these super sticky strains are making waves.

What makes a Cannabis strain frosty? 

Have you ever hooked up frosty strains of weed so dank that they clog up your crusher and stick your scissors shut? When it comes to putting the 'sticky' in sticky-icky, the credit goes to the trichomes found all over your frosty buds. Trichomes produce the diverse cannabinoids, flavonoids, and terpenes found in Cannabis, giving various strains their unique flavor profiles. Found in multiple plants and even algae, the chemical compounds produced by these trichomes serve a range of vital functions, such as defense against certain fungi and pests and aiding in pollination.

Several types of trichomes occur on Cannabis plants, giving the flower its shiny, hairy texture with a light dusting of powder. The largest and most important of those are called Capitate-stalked Trichomes. These trichomes, clearly visible under a general magnifying glass, look like stalks with a crystal ball perched on the top.

Trichomes have become a common indicator for growers, announcing the optimum time to harvest. Growers know by observing the opacity of the trichomes, which change from clear to milky to a light shade of amber. From there, the trichomes begin to degrade. This method isn’t surefire and may not necessarily apply to all strains, but its occurrence is vast enough to have become a common go-to.

The two other trichomes found on Cannabis plants are Bulbous trichomes and Capitate-sessile trichomes. These microscopic trichomes occur most commonly on leaves and stalks; however, do not overlook their benefits – they also contain their fair share of cannabinoids and terpenes. Trichomes start developing in the flowering stage of your Cannabis plant’s life cycle, covering everything but the roots in fine hairs and glistening crystals. They are especially noticeable on the newly bloomed flower.

Why are some strains considered ‘frosty’?

Many strains get their “frosty” moniker based on their snowy appearance caused by high amounts of resinous trichomes that form all over the flower. 

How does frosty differ from sticky?

Almost all Cannabis strains worth their salt have a certain degree of stickiness due to the coveted resin that all smokers pursue. But not all Cannabis strains result in a white, frosty appearance. This is reserved for the extra frosty strains with high trichome content hardwired in their genetics.

Tips for growing Cannabis with frosty features

Not just any strain can qualify for frosty status. No matter how much love and attention you give your plants, the quantity and quality of your trichome content are largely dependent on genetics and various environmental factors.

Use good lighting

Once you’ve acquired the seeds of some white, frosty weed strains and a good spot to grow,  you want to focus on lighting. To best encourage trichome production, avoid excessive heat and humidity. That’s where LEDs are an excellent option. They generate vast amounts of light through a broader spectrum while maintaining a cool environment, preserving trichomes. Many growers find maintaining temperatures around 79°F gives the best results.

HPS grow lights are a popular option for growers in colder climates as their purpose is twofold: providing your plants with light and warmth. However, many growers have also experimented with CMH (Ceramic metal halide), known as LEC (light emitting ceramic) bulbs. They produce different results depending on which version you utilize. Certain LEC bulbs can be used from seed to harvest, greatly increasing your trichome production but may lower the yield. 

Lastly, certain wavelengths of light, like UV-A and UV-B, seem to affect trichome production positively. This explains why you see all those frosty purple weed strains illuminated by bright purple UV lights in popular marijuana magazines. Always wear eye protection to block harmful rays when dealing with UV lights.  

Focus on the environment  

Environmental factors will play a large role in trichome production. If you’re hoping to grow the most frosty weed strains, there are a few things you need to keep in check. You want to maintain a comfortable temperature, and as the late flowering phase approaches, it’s best to keep humidity between 30 and 40%, especially in the last two weeks of flowering.

Maintaining a regular nutrient cycle will result in healthy plants, and healthy plants will produce better quantities of trichomes. Adding less nitrogen or extra UV light in the last two weeks of flowering can also promote better trichome production. However, adding UV lights can risk creating hermaphrodite plants, foxtails, or possibly putting your plants under light stress, so keep a close eye on your plant.

Practice plant training  

Utilizing plant training methods has become a popular trick for increasing plant mass, resulting in greater yields and higher trichome production on frosty white weed strains. Many of these methods involve putting the plants under stress or removing much of your plant’s foliage.

Super cropping involves pinching and twisting the stalks of your plants, putting them under stress to encourage growth throughout the vegetative phase. Cropping causes your plant to repair itself while adding extra bud sites by forcing it to take up more water and nutrients as a defense mechanism.
