Periodically opening containers to release built-up gasses, allowing for proper moisture regulation. This method helps prevent mold and enhances the curing process by promoting a controlled environment for optimal flavor, aroma, and potency development in the buds. Burping is a crucial step in achieving a high-quality final product, ensuring that excess humidity doesn’t compromise the integrity of the cured cannabis.

The period of dryness in between irrigation sessions. Growers intentionally reduce watering to allow the plant to use up remaining nutrients and moisture. This practice aims to enhance the flavor and smoothness of the final product by minimizing excess nutrients and preventing issues like nutrient lockout. It’s a strategic step in the cultivation process, contributing to the overall quality of the harvested bud.

The first part of the flower that develops, it’s a system of protective sepals (small leaves) to guard the plant’s developing reproductive organs.

(Compact Fluorescent Light) grow lights are a type of energy-efficient lighting commonly used in indoor cultivation. They emit a broad spectrum, including wavelengths especially suitable for the seedling and vegetative stage as they are not as powerful or energy-efficient as some other types of grow lights.

A condition in plants where the leaves or tissues turn yellow due to insufficient chlorophyll production. In cannabis cultivation, chlorosis can be caused by various factors, such as nutrient deficiencies, pH imbalances, or pests, disrupting the plant’s ability to carry out photosynthesis. Identifying and addressing the underlying causes of chlorosis is crucial for maintaining healthy cannabis plants and ensuring optimal growth and development.

A natural, organic growing medium derived from the husk of coconuts. An excellent alternative to traditional soil, it’s known for its high water retention and aeration properties for promoting root development, nutrient absorption, and overall plant health.

Technically not “true leaves,” they are the first leaves that appear on a plant and sometimes known as “seed leaves,” or “embryonic leaves.” Smooth and rounded, cotyledons serve to supply the plant with stored nutrients until the first true leaves can grow.

An advisable practice for the final two weeks of flowering, growers should discontinue the administration of fertilizing agents and use only pH-balanced water until harvest. Users will enjoy clean, harvested bud that is void of harsh chemicals.

A cultivation approach focused on promoting reproductive development, particularly flowering and fruiting. This phase is characterized by a shift in the plant’s energy allocation towards producing flowers and ultimately seeds. In cannabis cultivation, generative growth is crucial for achieving a bountiful harvest of potent and mature buds, requiring specific adjustments in light cycles and nutrient ratios to support flowering and enhance cannabinoid production.

Optimal conditions trigger dormant seeds to release hormones that activate the growth stage of the plant’s life cycle. When light, temperature, and moisture are prime, the seed’s taproot will emerge, initiating germination.

High-Pressure Sodium lights are high-intensity discharge lamps that emit a spectrum rich in red and orange wavelengths, ideal for stimulating flowering and fruiting. Widely used in indoor cultivation, HPS lights enhance photosynthesis, encourage robust bud development.

A widely referenced botanical classification of the cannabis plant that has a genetic lineage of both indica and sativa. While most strains in this category are indica or sativa-leaning, some are “balanced,” meaning that they are of a 50:50 parentage strain ratio. Users tend to report effects characteristic of both parent categories.

A widely referenced botanical classification of the cannabis plant that appears short and bushy, with robust, serrated leaf fingers. Users tend to report calming and sedative effects as opposed to yield from the other two common categories: sativa and hybrid.

A neutral substrate that does not contain any inherent nutritional value or additives. It is a foundational medium in which the roots of the plant can take hold and growers are in control of how, when, and with what to supplement nutrients.

A handful of origin plants from which all cannabis strains have emerged. Tracing direct lineage from a landrace strain implies a prestigious pedigree.

A cannabis cultivation technique that involves gently manipulating the plant’s structure to optimize light exposure and promote even bud development. Instead of causing stress by pruning or topping the plant, LST involves bending and tying down branches to create a more horizontal canopy for better light distribution. It is often used during the vegetative stage to enhance yields and create a more manageable and efficient use of space.

The death of cells or tissues, which often results in darkening, wilting, or browning. In cannabis cultivation, necrosis can occur due to factors like diseases, extreme environmental conditions, or nutrient imbalances, leading to the deterioration of plant tissues. Prompt diagnosis and corrective measures are essential to mitigate necrosis and sustain the overall health and vitality of cannabis plants.

The point on the plant stem where leaves, branches, or buds emerge.

Also known as “fertilizer burn,” or “nute burn,” it’s recognizable by the tips of the leaves appearing, yellow and curled as though they have been burned with a flame. Caused by an excessive delivery of nutrients at the root level, this problem disrupts the circulation of water throughout the plant. To troubleshoot, make sure you’re using the correct suggested nutrient combo for where you are in the growing process. Consider the dosing directions on the label of your fertilizer to be the maximum dose; in most cases you should be starting the dose at about half of what’s on the label. If nute burn is happening, flush your plants for a few days by cutting back on nutrients and water using pH-balanced water.

(Photosynthetically Active Radiation) is a crucial metric in cannabis cultivation, representing the spectrum of light wavelengths that plants use for photosynthesis. PAR light encompasses wavelengths between 400 to 700 nanometers, which are essential for plant growth and flower development. When cultivating cannabis, optimizing PAR light levels ensures efficient photosynthesis, promoting robust vegetative growth and ultimately maximizing the yield and quality of the harvested buds.

A growing substrate derived from partially decomposed sphagnum moss, it’s an effective soil amendment ideal for water retention and aeration. As a key component in many potting mixes, peat moss aids in promoting nutrient uptake, root development, and overall plant vitality during the growth cycle.

Part of the reproductive system of a female plant, they appear as long hairs stemming conspicuously from the buds. By observing the maturation of the pistils, you can discern when to harvest the bud. As their color transitions from white to orange, amber, and brown, they are nearing harvestability.

The reproductive parts of a male plant, they are also known as “bananas” in industry jargon. Appearing as large bulbs at the nodes of the plant, they contain the pollen necessary to fertilize a female plant. Pollen from these sacs is harvestable and bankable for those hoping to use it for a breeding program. Sometimes, they can appear alongside the hair-like pistils, characteristic of a female plant. This means your crop has produced a “hermie,” or hermaphroditic plant that has biologically adapted to the absence of true male plants. Most experts agree that it’s best to ditch hermie plants.

Also known as “damping off,” “dampening off,” and “root rot,” Pythium wilt is root-level rotting caused by the presence of several fungal species. Stems become thin, weak, and dark, rendering them incapacitated for circulating fluid. The main cause is over-watering and/or insufficient drainage, resulting in a soggy growing medium that grows a fuzzy fungal blanket at the base of the plant. Increasing light strength can help curtail the fungal growth, as well as cutting back on watering, and ensuring there is plenty of drainage and airflow.

A widely referenced botanical classification of the cannabis plant that appears tall and slender, with narrowed, serrated leaf fingers. Users tend to report energizing, uplifting effects as opposed to yield from the other two common categories: indica and hybrid.

Pores on the leaves that open and close. They take in carbon dioxide and release oxygen during photosynthesis while also regulating the loss of water vapor. These pores help plants balance their need for carbon dioxide and water in a sort of natural breathing process.

Noticeable throughout the growth phases, the plant will “stretch” towards the available light. In the seedling stage, this means that the light strength is insufficient and needs to be increased. Since this could result in a weak stem, troubleshoot by moving the light system closer to the plants. In the vegetative and early flowering phase, it is normal for the plants to drastically increase their height, as long as they are braced to assist their load-bearing branches.

The small, resinous leaves that surround the flowers or buds of the plant. These leaves are coated with trichomes, which contain cannabinoids and terpenes, contributing to the potency and flavor of the cannabis. They are valued for their resin content and can be repurposed for concentrates or edibles, enhancing the overall yield and versatility of the harvest.

Pushing through the seed’s protective outer shell, the taproot is the plant’s first and main root. It will serve to anchor the plant, and from it, all of the other roots will emerge. It absorbs water and nutrients, crucial to the plant’s health and maturation.

The process by which plants lose water vapor through small pores, known as stomata, primarily located on the leaves. This natural and essential physiological activity is driven by the plant’s need to absorb water and nutrients from the soil, as well as to cool itself and facilitate the upward movement of water through its vascular system. Transpiration plays a vital role in maintaining plant hydration, nutrient transport, and overall growth.

The natural defense system for the plant, trichomes are microscopic hairs with a filamented-mushroom shape when magnified. They contain the phytochemicals (cannabinoids and terpenes) responsible for the bulk of the effects experienced by consumers. From afar, they appear as a frosted blanket covering the flowers and their surrounding leaves. Through the transition from transparent to white, opaque, and finally, amber, the potency of the product is increasing and flowers are nearing harvestability.

A value that is crucial for measuring and understanding a plant’s capacity for transpiration, it is the difference between how much moisture is in the air and how much moisture the air can hold. Keeping the right VPD helps plants breathe and take in nutrients effectively, ensuring they grow healthy and strong.
