How to grow cannabis for produce concentrates

concentrati cannabis tecniche coltivazione migliorareresa

Cannabis is most commonly consumed as a flower, so many growers focus on achieving high yields to increase profits. But some prefer to focus on the burgeoning concentrate market.

Growing for concentrates is slightly different than growing flowers because the ultimate goal is to have a plant that produces many trichomes so that you have that flower then processed. Trichomes are the glandular crystals that form on cannabis buds that contain cannabinoids and terpenes. They can also be referred to as resin, crystals or sugar.

The cost to ship the material to be processed for concentrates can be a financial deterrent for some growers; however, with rosin technology, many growers are now able to transform their concentrates to obtain high-end oil.

What makes an excellent plant for concentrates

If you’re going to concentrate the flavours of a variety, it’s better to start with something that already has a delicious and high taste that you like.

To get a good concentrate, you have to start with an edible flower. The best concentrates are extracted from a quality flower that produces heads of bulbous trichomes.

Plants that produce heads of large trichomes will have more oils, which in turn can contain more cannabinoids and terpenes.

It is particularly essential to have large trichome heads when making the solventless hash because they will break down more quickly in the hash making process.

Strains with multiple terpene profiles can produce unique flavours. Sometimes it’s worth exchanging a high return for the novelty: complexity and rarity can be a high concentrate. If you have a special effort, turning it into a focus can make you appreciate its subtle qualities even further.

How to improve the quality of your plants

Because concentrates concentrate on the terpene and the aromatic profile of a strain, you don’t want unwanted compounds like those found in pesticides and nutrients to end up in your concentrates. Here are some ways to improve the quality of your plants by protecting and preserving terpenes.

Use a complete soil

This soil is loaded with most of the nutrients the plants need, all inorganic form, making it easier for the roots to absorb them.

Avoid foliar spraying

Leaf spraying helps to combat nutritional deficiencies and pest problems. You want to avoid this practice when the plants are in bloom, as the residue will present itself as a contaminant in your concentrate. If you need to spray the plants, do it before flowering and use only organic sprays.

No pesticide

Stay away from hazardous chemicals that cannot be eliminated from your harvest. These will take you to your concentrates and are dangerous to consume. Consider using integrated pest management strategies, predatory mites or organic foliar sprays to keep your garden healthy without affecting the flower.

Flush Your Crop

If it grows with non-organic fertilisers or nutrients in the soil or water-based soil, give your plants only water in the last two weeks of flowering before harvest. This will give them time to find impurities, making the flower cleaner and therefore a cleaner concentrate.

Tips and tricks to increase the production of trichomes

These simple methods can have a significant impact and significantly improve the quality of the final product.

Room temperature

The specific terpenes begin to disintegrate at room temperature, making the climate control in your grow room essential for the quality of the flavour of your concentrate. You can use an air conditioning system and even an infrared heat reader to observe the temperature of your colas when the plants bloom. Ideally, you want your hair to be less than 75 degrees.


CO2 is an essential part of photosynthesis, and without it, your plants will not be able to utilise nutrients fully. Give plants a push with a CO2 burner to increase the size of your plants both during the vegetative and flowering phases. Larger plants will have more surface and therefore more resin due to higher yields.

Cold finish

This is open to debate, but some growers argue that reducing the temperature in the cultivation room just before the harvest can bring cannabis plants to increase the production of trichomes.

The idea is that stress created by lowering the temperature will cause a cannabis plant to produce more trichomes in an attempt to protect itself. When a plant is about to die, it will provide more resin to attract more insects to pollinate. Some growers will even interrupt the irrigation of a plant a few days before being harvested to induce stress

Consider lowering the temperature to 60 ° low no more than two weeks before harvest, when the shoots are mostly grown.

What to do after the harvest

The last step in accentuating delicious terpenes in your cannabis comes to the crop. Some growers freeze their buds without hardening before concentrating, while others prefer to heal before concentrating.

Here are some different approaches to how to store terpenes after harvesting.


Freezing prevents terpenes and cannabinoids from breaking down and capturing the new profile of a plant when its terpene content is the highest.

If you are planning to concentrate within a couple of weeks of harvesting, you can completely skip the healing process and freeze your buds. You will need to remove the fan leaves and lower the coals until all the buds are bigger than a golf ball or other and then pack the buds.

Drying and hardening

If you are not sure of turning your flower into concentrate at harvest time, drying and treating your plants properly is a must to protect the trichomes. Hang your plants, so you have plenty of room to breathe in a place with good air circulation, at a temperature between 60-70 ° F with a humidity of 45-55%.

When the drying is complete, place your buds in glass jars where they can cure slowly. Making the eyelids appear a few times a day at first to let the buds breathe and release the moisture. The extra time, opening the jars will become less necessary, and the gems will improve continuously, usually up to 6 months.

As mentioned above, some terpenes will break down at room temperature (70 ° F). So keep the polymerisation temperatures between the high 50s and the 60s with 55% humidity to maintain quality.
