The choice of seeds is the first link in the chain of decisions that will define the cultivation of marijuana. Cannabis sativa subsp. indica is known for its manageable height, fast flowering and dense buds; it is a frequent choice for therapeutic use due to its more body-like effects. On the other hand, Cannabis ruderalis, with its small stature and adaptability to cold climates, is less well known but ideal for those with limited space or challenging climatic conditions.

When choosing a seed, you should keep in mind not only your personal preferences for taste and effect, but also the genetics and challenges each strain may present during cultivation. In addition, if you opt for autoflowering marijuana plants, you will need to handle them with special care due to their accelerated life cycle that allows them little recovery time from stress.

In this complex dance of decisions, it is important to consider your own capabilities as a grower. Are you up to the challenge that each type of seed represents? Choosing marijuana seeds is not a mere act of selection, but a statement of intent. Choose wisely and you will be sowing the seeds of success.

Optimal Climatic Conditions for Cultivation

Marijuana plants, like all living creatures, require specific conditions to reach their full potential. Seedlings need:

  • A generous amount of light, ideally 18 hours or more per day, for optimal development.
  • When these young marijuana plants venture outdoors, they seek at least 6 hours of direct sunlight, supplemented by several hours of indirect sunlight for healthy vegetative growth.
  • Temperature also plays a determining role, with an optimal range between 20°C and 28°C during vegetative growth and a slight reduction during flowering to favor the production of high quality marijuana buds.

Humidity, that invisible mantle that envelops our marijuana plants, must be kept in a delicate balance. During the seedling stage, in a propagator, a relative humidity of 70% is ideal, decreasing to 40-50% at flowering to avoid problems such as mold. These climatic parameters are vital and should be monitored closely, as adequate water and heat will determine the fate of the plants from their initial growth.

After all, the climate in your growing area will largely determine the techniques and strategies to be employed to keep your marijuana plants happy and productive.

The soil in which marijuana plants grow and the nutrients they receive are critical to their health and productivity. The main macronutrients required by the marijuana plant are Nitrogen, Phosphorus and Potassium, each playing a crucial role at different stages of growth. During the fattening phase, for example, plants need higher amounts of Phosphorus and Potassium to develop large and resinous buds. This supply is made approximately one month after the beginning of flowering, when the flower tails start to form.

The use of additives such as Bud Candy can provide additional sugars during the flowering stage, improving the quality of the marijuana buds. In addition, the choice between substrates such as soil, hydroponic and aeroponic, as well as between organic and mineral fertilizers, will depend on the advantages and disadvantages that each offers in the context of the specific marijuana crop.

Substrate and nutrient optimization is a technical aspect that requires ongoing understanding and adjustment, but is essential to ensure that your marijuana plants reach their full potential.

Harvest and Post-Harvest: Final Processes

Reaching the harvest stage is a milestone in every marijuana grower’s life, a moment that marks the culmination of months of work and care. Once you have confirmed that your marijuana plants are mature, the careful process of harvesting with pruning shears begins.

Manicuring, whether green or dry, prepares the buds for drying, an essential step that, if done correctly, preserves the quality of the cannabinoids and maximizes the potency and flavor of the final product.

Curing, although often underestimated, is equally critical to the development of a high quality product. This process, which typically lasts from two weeks to several months, is essential for removing residual water, preventing mold and improving the preservation and flavor of the smoke.

By devoting time and attention to each of these final steps, you can ensure that your marijuana buds are of the highest possible quality, ready to enjoy or take to market.

Ideal Time to Harvest

Determining the optimal time to harvest your marijuana plants can be an art in itself. Trichomes, those little stems with a mushroom-shaped end, are one of the best visual tools for judging the maturity of your plants. When the trichomes are transparent, it is a sign that it is still early to harvest, as the plant has not produced enough cannabinoids and terpenes. As the trichomes become opaque and milky, this indicates an increase in cannabinoid concentration, which is ideal for a classic, THC-rich marijuana harvest.

The amber coloration of the trichomes suggests a more advanced maturity and a more relaxing effect of the final product. Most marijuana growers seek to harvest when most of the trichomes are mature but before they all change to amber to obtain a balance between potency and effect. Watching your plants and learning to read these little indicators will help you make the right decision and harvest at the right time to get the desired results.

Manicuring and Drying the Buds

After harvesting, trimming is the first step in preparing the marijuana buds for consumption. You can opt for fresh manicuring, which involves removing the sugar leaves immediately, or dry manicuring, which is done once the buds have lost their water content. Both techniques have their advantages, and the choice depends on the grower and drying conditions.

The process of drying the buds is critical and must be done carefully, as drying too quickly can degrade the quality of the cannabinoids, while too slow a process can encourage the development of mold.

For proper drying, it is important to keep the following in mind:

  • Make sure you have adequate air circulation during drying.
  • Optimal relative humidity is between 45-55%.
  • The average drying time is 7-12 days, but can vary depending on the environmental conditions and the size of the buds.

By following these tips, you will be able to obtain good quality buds.

Once the buds are properly dried, they are stored in airtight containers to start the curing process, which lasts at least two weeks and can be extended up to 4-8 weeks to further develop the flavor and aroma of the marijuana buds.

Curing: Improving Flavor and Potency

Curing is an often overlooked post-harvest stage that has a huge impact on the final quality of marijuana buds. During this process, humidity is slowly reduced, allowing terpenes and cannabinoids to develop and be preserved in the buds. Cannatrol’s Vaportrol technology, for example, has been approved by European patents and offers a comprehensive system for drying, curing and storing cannabis, improving product quality and preservation.

Terpene retention with this technology is 16% higher than traditional methods, contributing to a richer flavor profile and a better consumption experience. In addition, this technology is suitable for a variety of grow sizes, from personal to large-scale production, demonstrating the versatility and adaptability of innovations in the cannabis cultivation sector.

Curing is a phase where patience is rewarded with a marijuana product of enhanced flavor and potency, and should not be underestimated by any serious grower.

In Spain, the legal landscape for marijuana cultivation has undergone significant changes in recent years. It is legal to buy and consume CBD flowers, as long as the THC content is less than 0.3%. This has opened the door to an emerging market for cannabis products with therapeutic effects and without the psychoactive effects of THC.

However, it is important for marijuana growers to be well-informed about current laws to avoid legal problems. Be sure to keep your grow within the confines of the law, which will not only protect your investment but also allow you to enjoy the fruits of your labor with peace of mind.
