Larf Cannabis: What Is It And Is It Good For

Larf cannabis is immature buds that have not reached their full potential. It is usually located on the lower branches of the cannabis plant. Since it is living in the shadows of bigger buds or colas, it lacks light penetration contributing to their immaturity.

Immature buds will appear airy and flacid. Since these buds don’t mature properly it has less THC and CBD. If you are growing indoors the lighting setup contributes to this type of buds.

De-larfing is a practice of marijuana growers to minimize larf. They ensure that the buds get enough energy through cannabis training and pruning. Declaring increases cannabis production and it maximizes the yields. Larf buds produce same effects to the cannabis users but just in small concentration. It does not have sales appeal because of its quantity and its concentration.

If you are growing outdoors it may be because of the exposure to high temperature. If you see that the buds stop producing crystals and resin, if the smell has reached its peak and if the bud’s size has not increased for a few days it means that the cannabis buds will no longer enter into maturity.

Common Causes of  Cannabis Larf

  • Changes in photoperiod especially if there is an abrupt change in the lighting hours
  • Wrong environmental conditions: too humid, too cold environment
  • Mechanical stresses like damages roots, lack of nutrients, broken branches etc.
  • Diseases on pest infestations
  • Thermal stresses like watering cannabis with cold or hot water
  • Use of phytotoxic such as pesticides and fungicides

How to Prevent Larf Cannabis

1. Use a Good Strain

The importance of genetics will determine the appearance, smell, taste, and potency of your cannabis buds. The different kind of strains brings different kinds of success to each and every grow. Choose a strain that works best for you depending on your lifestyle, growing set-up, and some environmental factors. There are real strains that don’t provide you with dense buds.

Most Indica strains end up with a denser bud but this is not a guarantee, it would still depend on how you would grow this strain. The Sativa strain provides a not so dense bud but these strains provide more potent effects that give out a perfect high.

2. Amount of Light

In growing cannabis indoors, the amount and type of light are important. Even if you have the best type of light if positioned it incorrectly then your resources are just put to waste. The lighting period is essential to growing cannabis.

In growing outdoors, make sure that your buds receive at least 8 hours of sunlight exposure to maintain the plant’s proper moisture, if it is too hot don’t expose your cannabis plant too much because it may burn the leaves.

If you would use manufactured lights such as CFLs or LED lights it is better to ask the manufacturer about its designated distance. You also need to have a broad knowledge about how the light spectrum affects the growth of cannabis. If you don’t have a budget for too many lighting setups, it is advisable to make use of reflectors to ensure that the light rays are somehow properly distributed throughout the growing area. Make sure every angle of the medical cannabis plant especially the buds to make it dense and large.

3. Temperature

It is important to ensure that you provide your cannabis plant with the right level of temperature to enable the buds to reach its maximum potential. It is important to choose the right strain for your climate so that it is easier for you to control the temperature.

The optimum temperature of the cannabis plant to thrive in is between 65 degrees Fahrenheit-80 degrees Fahrenheit. Most Indica strains have less capability of handling too much high temperature while Sativa strains can easily adjust to the high temperature. If your cannabis plant is sitting on a hot temperature there are sprayer system available in the market to act as a cooler reagent that can help cool the air surrounding your cannabis plant.

4. Nutrients

Nutrients are the most important especially during seedling until the vegetative stage. The absorption of nutrients depends on the right PH level of the soil. When your cannabis plant starts to bud, it needs a high quantity of potassium and phosphorus. There are particular nutrients to be given to each phase. Follow some guides to ensure that your cannabis plant is fed accurately.

Only add supplements such as sugar, amino acids and additives to your plant if you know that you have already enriched it with the base nutrients. Supplements are an additional factor in order to boost bud development.

There are two supplement types that are for bloom-boosters. The first type is for the enhancement of the plant process that uses amino acid and minerals. The second type is a supplement for growth which enhances the availability of phosphorus and potassium.

5. Ventilation

Cannabis plant needs proper airflow if it receives bright light. If the buds are isolated and not exposed to air there is a higher chance that it will not get fat and dense. One way to ensure that the airflow is distributed equally is by defoliating by removing the leaves that block the pathway of the air to the buds.

Buds should have at least a few inches away from each other. However, defoliating is not recommended if your cannabis plant is unhealthy. An alternative instead of cutting the leaves is to just fold or tuck in the leaves.

6. Healthy Roots

Healthy roots are equal to having a healthy cannabis plant. Your roots need enough water and oxygen supply. To have healthy roots you need to observe proper watering because over and under watering your cannabis can harm not only your roots but it harms your cannabis plant in general. If your cannabis plant is healthy then it can produce large and dense buds.

7. Humidity

The humidity level should be consistent during the flowering stage to ensure that the plant is protected with a mold infestation. Molds are the number 1 destroyer of buds.

8. The timing of the Harvest

The proper timing in harvesting the cannabis bud is one of the ways to ensure that the buds reach its full maturity, size, and potency. The proper time of harvest may vary from one strain to another that is why proper knowledge about the strain you’re into is necessary. Harvesting too soon will let you get immature buds.

If 60%-70% of the hairs have darkened it means that the THC content reaches its maximum level. If 70%-90% of the hair has darkened it means that your strain is more of a strain that has calming effects CBD.

Techniques To Prevent Cannabis Larf

1. Lollipopping

This is a type of pruning that lets you remove all the lower infant buds during the early stage of flowering phase. In this way, the cannabis plant won’t waste time and energy producing a larf.

2. SCROG Method ( Screen of Green)

In this method, the cannabis plant is stretched over the entire area to produce a canopy that enables the cannabis plant to receive optimum sunlight and proper ventilation. The goal of this method is to ensure that the buds will reach its maximum potency until harvest.

3. Low-Stress Training

It is where you bend the cannabis plant as it grows. You need to tie the larger branches down so that the auxin is distributed evenly on the plant. The goal of this training method is to have more stalks that can produce bud sites.

4. Pruning

This method is essential as the cannabis plant begins to have a bushy shape. The target of pruning is to remove the small branches that receive little to no amount of sunlight, drying leaves because of lack of light and bud sites that are not properly attached to the plant’s main stalk.

5. Super Cropping

As the plant grows bushier with more buds this is the perfect time to even increase the yields. This method is done during the vegetative stage. You need to exert gentle pressure to the branches that aim to have a flat canopy at the top of the cannabis plant.

Super cropping encourages the growth hormone to be distributed to other areas such as those parts that don’t receive enough nourishment.

What Can You Do With The Larf Cannabis

Even though the concentrations of CBD and terpene level is low it can still be used in several ways:

1. Cannabis Oil

This is used for preparing infused edible. Here are the steps in preparing cannabis oil:

Step #1: Grind the cannabis larf. Just grind your larf just enough to fit in your strainer. If you grind your larf into powder, there is a tendency that you won’t maximize its potency.

Step #2. In a mixing bowl, combine your ground cannabis leaf with a little bit of cooking oil on low fire for hours. This process is called the decarboxylation where the THC content is activated. To avoid it from burning to add 1 cup of water make sure that the heating temperature won’t exceed 245 degrees Fahrenheit.

Step #3. Strain the oil using a cheesecloth. You can be extended the shelf life of the cannabis oil for 2 months in the refrigerator.

2. Joints

It is a way of consuming cannabis through the use of a paper roll. Here are the steps to prepare joints:

Step #1. Grind your cannabis larf. Make sure that the cannabis larf is dried enough. It is better to use a hand grinder to ensure that you won’t make it into powdery one.

Step #2. Create a joint/crutch filter. The use of a filter is to block bits of cannabis plant from getting into your mouth. It is a mouthpiece in the form of a hard paper. Make a fold at the end of the hard paper and roll the material into your own desired thickness.

Step #3. Fill the joint paper with the ground cannabis larf. There are available joint paper in the market with flavors. Once you filled in your joint paper with cannabis larf you can now begin to form it into rolls.

3. Another use of cannabis larf is to make it resin or concentrates in edible product

Tips to Avoid Having Larf Cannabis

  • It is important to remove dying leaves. Dying leaves can be identified through their yellowing color. These dried leaves still use energy resources that could be focused more on making the buds bigger.
  • Manipulate the cannabis plant structure. The production of cannabis larf is due to their positioning where it is not directly receiving light and air.
  • Everything comes down to genetics. If you would invest in low-quality seeds then there is a big chance that your harvest will be unsuccessful. The appearance and size of the buds are perfectly determined by genetics.

Steps in Harvesting Larf Buds

1. Pluck the stems using a pair of scissors. Pulling it downwards is the easiest way to detach the larf buds from the main stem.

2. If the larf buds contain fan leaves, Remove it downwards towards the roots. The fan leaves do not contain any cannabinoids that are why it is fine to discard it.

3. Wash your larf buds. The first step in washing your larf buds is to let it stay in the mixture of baking soda, lemon, and water for about 10 minutes. The next step is to immerse it in tap water for another 10 minutes to remove the residues of the baking soda and lemon. The last step is to immerse the larf buds in cold water for 5 minutes.

4. Let the cleaned larf buds drip off. Hang it off for one day or until the buds to dry.


Cannabis cultivators goal is to produce the biggest and healthiest buds. It will become a sort of disappointment on their part to get yields that were not fully developed. Cannabis growers remove these larf to make it to something special so as not to waste it because it still contains potency like that of a regularly sized cannabis bud.
