Cannabis Knowledge & FAQ

Green Cart is a private, members-only online cannabis club based in South Africa. We are a community of adults who share a passion for cannabis culture, education, and quality products. Everything we share is for educational purposes within our private membership community.

A private cannabis club is a members-only community where South African adults come together to share knowledge, education, and a passion for cannabis. Membership is private, age-verified, and governed by a code of conduct. Green Cart operates on this model to ensure a responsible and informed community.

Green Cart membership is open to South African adults aged 21 and older. Persons under 21 are not permitted to join, unless a registered South African medical practitioner has indicated a specific medical or therapeutic need. All members must agree to our terms of membership and code of conduct.

The Constitutional Court of South Africa (Case CCT 108/17) decriminalised the private use, possession, and cultivation of cannabis by adults in private spaces. Commercial regulation is still being developed through ongoing legislative processes. Green Cart operates within this legal framework and shares all content purely as education and community knowledge.

The private membership model allows Green Cart to create a safe, responsible, and age-verified community. It ensures that educational resources are only accessible to verified adults and that our community standards are upheld at all times.

No. All content on Green Cart is intended for adults aged 21 and older only. If you are under 21, please exit this platform. Cannabis is not suitable for minors. If you are under 21 and using cannabis for a medical reason, please do so only under the direct guidance of a registered South African medical practitioner.

Cannabis flower — also known as bud — is the harvested, dried, and cured reproductive part of the female cannabis plant. It contains the highest concentration of cannabinoids and terpenes and is the most widely recognised form of cannabis in South Africa and globally.

Indoor flower is grown in a fully controlled environment with artificial lighting, typically producing dense, aromatic, and potent buds. Greenhouse flower benefits from natural South African sunlight with some environmental controls, offering a good balance of quality and yield. Outdoor or sun-grown flower uses natural conditions with minimal intervention — often resulting in larger yields but with more variability depending on the climate.

Curing is the process of slowly drying harvested cannabis flower in controlled conditions over several weeks. Proper curing breaks down chlorophyll, reduces harshness, preserves terpenes, and develops a smoother, more complex flavour and aroma. Poorly cured flower can taste harsh and grassy, and loses much of its character.

South Africa's warm climate makes proper storage especially important. Store flower in an airtight glass jar away from direct sunlight, heat, and humidity. Ideal relative humidity is between 55% and 62%. Boveda or similar humidity packs help maintain this. Avoid plastic bags as they degrade terpenes and damage trichomes. In summer, consider keeping your jar in a cool room or wine fridge.

Trichomes are the tiny, crystal-like glands that coat the surface of cannabis flower and leaves. They produce and store cannabinoids, terpenes, and flavonoids. A heavy trichome coating — often described as 'frosty' or 'sugary' — generally indicates a well-grown, resin-rich flower. Trichomes are also the starting point for concentrates like hash and rosin.

THC percentage indicates how much of the dried flower weight is made up of tetrahydrocannabinol. However, it does not tell the full story — the presence of other cannabinoids, terpenes, and how the product is consumed all affect the overall experience. At Green Cart, we always encourage looking beyond the number and considering the full cannabinoid and terpene profile.

The entourage effect is the widely discussed theory that cannabinoids, terpenes, and other plant compounds work better together than in isolation. A full-spectrum flower experience is believed to produce more nuanced and rounded effects compared to isolated compounds. This is one reason why whole-flower education is central to what Green Cart shares with its members.

These are traditional classifications used widely in South Africa and globally. Indica varieties are generally associated with a more body-focused, relaxing experience. Sativa varieties are often described as more uplifting and cerebral. Hybrids are crosses between the two. In modern cannabis science, terpene and cannabinoid profiles are considered better predictors of effect than plant type alone.

Hash rosin is a premium solventless cannabis concentrate made by applying heat and pressure to bubble hash (ice water hash). Because no chemical solvents are used in the process, hash rosin is considered one of the cleanest and most flavourful concentrates available. It is one of the products Green Cart educates its members about as part of our concentrate knowledge series.

Bubble hash — also called ice water hash — is made by agitating cannabis in ice-cold water. The cold causes trichomes to become brittle and break off. The mixture is filtered through a series of mesh screens (micron bags) to collect trichome heads, which are then carefully dried to produce a powdery or sandy hash. This forms the starting material for hash rosin.

Star ratings refer to the quality grade of ice water hash. 6-star (full melt) hash is the highest grade — it melts completely when heated, leaving no residue, containing almost purely trichome heads. Lower grades (1–3 star) contain more plant material and are generally better suited for pressing into rosin. South African producers and collectors use these same international grading standards.

Ice water hash is thoroughly dried, then pressed between parchment paper using a rosin press at carefully controlled heat and pressure. The heat causes the oil-rich trichome heads to release their contents, which are collected as rosin. The quality of the starting material and the pressing technique directly determine the final product quality.

Hash rosin appears in several textures depending on pressing conditions and post-processing: budder (creamy and whipped), badder (slightly looser), jam or sauce (wet and saucy), cold cure (firm and waxy), and fresh press (runny, direct from the press). Each has slightly different handling, storage, and flavour characteristics.

Hash rosin should be kept in a sealed glass or silicone container in a cool, dark environment. In South Africa's warmer regions, refrigerator storage is recommended. For long-term storage, a freezer is ideal. Heat, light, and air degrade terpenes and cannabinoids over time, reducing quality.

Generally, yes. Hash rosin is a concentrated extract with a significantly higher cannabinoid content than dried flower. This means the experience can be considerably more intense. Those who are new to concentrates should approach with extra caution and start with very small amounts — this is advice Green Cart emphasises strongly.

A dab rig is a specialised water pipe designed for vaporising concentrates. Hash rosin is placed on a heated surface (a banger or nail), which vaporises it at controlled temperatures. Low-temperature dabbing is preferred for hash rosin as it preserves terpenes and produces a smoother, more flavourful experience without burning the product.

Flower rosin is made by pressing dried cannabis flower directly between heated plates under pressure. It is the most accessible form of solventless rosin extraction and requires no solvents or chemical processing — just heat, pressure, and quality starting material.

Flower rosin is pressed directly from dried bud, which means some plant material can carry through into the final product. Hash rosin starts from ice water hash — a more refined, trichome-rich starting material — resulting in a cleaner, more flavourful, and typically more potent concentrate. Hash rosin is generally the higher-quality option, reflected in its price.

Flower rosin yields typically range between 12–20% depending on the quality and moisture content of the input flower. High-resin, well-cured South African-grown flower tends to yield better. The starting material quality is everything — lower-grade flower produces lower-grade rosin.

Yes. Flower rosin is produced using only heat and pressure. No chemical solvents such as butane, propane, or ethanol are used at any stage. This makes it a clean, solventless extract — a key reason it has become popular among health-conscious cannabis consumers in South Africa.

Flower rosin can be dabbed using a rig, added to a joint or bowl (known as 'twaxing'), or used with a dry herb or concentrate-compatible vaporiser. Its texture is typically similar to hash rosin but may appear slightly darker or more amber due to plant matter from the original flower.

Live hash rosin is widely considered the pinnacle of solventless cannabis extraction. It is made from fresh-frozen cannabis — plant material that is harvested and immediately frozen rather than dried and cured. This preserves a far fuller and more complex terpene profile, producing a concentrate that closely represents the aroma and flavour of the living plant. It is among the most sought-after extracts discussed in the Green Cart community.

The live process requires fresh-frozen starting material, which adds logistical complexity and a tighter production window. The ice water extraction of fresh-frozen material is more delicate and lower-yielding. The end result — a highly aromatic, terpene-rich concentrate — commands a premium that reflects the craft and care involved.

Fresh frozen refers to cannabis that is harvested and immediately placed into a freezer, bypassing the traditional drying and curing process entirely. This locks in volatile terpenes and other compounds that would otherwise evaporate during drying — preserving the true character of the plant.

Live hash rosin typically has a more vibrant, complex, and true-to-plant flavour. Because the full terpene profile of the living plant is preserved, the aroma and taste are often described as fresh, fruity, floral, or intensely terpy — depending on the cultivar. Standard hash rosin is excellent, but drying and curing changes the terpene expression somewhat.

Not necessarily. The defining advantage of live hash rosin is its terpene richness and flavour complexity, not simply higher THC. Cannabinoid content depends on the cultivar used. The experience is often described as more rounded and expressive due to the fuller plant spectrum.

Live hash rosin is best consumed using low-temperature dabbing to preserve its rich terpene content. High heat burns off terpenes quickly, reducing the flavour complexity that makes live rosin worth its premium. Temperature-controlled e-nails or electric dab rigs — set typically between 157°C and 200°C — are popular among concentrate enthusiasts for this reason.

Cannabinoids are naturally occurring chemical compounds found in the cannabis plant. They interact with the human body's endocannabinoid system (ECS) — a network of receptors found throughout the brain and body. Cannabis contains over 100 known cannabinoids. Green Cart's education content covers the most relevant ones for members.

THC (tetrahydrocannabinol) is the primary psychoactive cannabinoid in cannabis. It binds to CB1 receptors in the brain and central nervous system, producing the well-known euphoric effect. It is also the subject of ongoing scientific research into various potential therapeutic applications.

CBD (cannabidiol) is a non-psychoactive cannabinoid — it does not produce the intoxicating effects associated with THC. It interacts with the endocannabinoid system differently and is the subject of significant global medical research. In South Africa, CBD products below a certain concentration threshold are regulated separately and available without a prescription.

CBG (cannabigerol) is often called the 'mother cannabinoid' because many other cannabinoids, including THC and CBD, are derived from its acidic precursor CBGA. CBG is typically present in small quantities in most cannabis cultivars and is an area of growing research interest globally.

CBN (cannabinol) is a mildly psychoactive cannabinoid that forms as THC ages and oxidises. It is often found in older or improperly stored cannabis. It is the subject of research for various potential properties, though much of the popular information about CBN remains anecdotal at this stage.

The endocannabinoid system is a biological system found in humans and many animals. It consists of endocannabinoids produced by the body, receptors (primarily CB1 and CB2), and enzymes. The ECS is involved in regulating mood, sleep, appetite, pain sensation, and immune response, among other functions. Cannabis cannabinoids interact with this system.

THCA (tetrahydrocannabinolic acid) is the raw, non-psychoactive precursor to THC found in fresh and live cannabis. It only converts to THC when exposed to heat — a process called decarboxylation. This is why raw cannabis flower does not produce psychoactive effects if eaten without being heated first.

Decarboxylation (or 'decarb') is the process of applying heat to cannabis to convert THCA into THC and CBDA into CBD, activating their respective properties. This happens automatically when cannabis is smoked, vaped, or cooked. It is an important concept for understanding how cannabis products work.

A full-spectrum product contains all the naturally occurring cannabinoids, terpenes, and other plant compounds found in cannabis — as opposed to an isolate (a single purified compound) or a broad-spectrum product (which typically has THC removed). Full-spectrum products are associated with the entourage effect, which is a key focus of Green Cart's education content.

Terpenes are aromatic compounds found in many plants, including cannabis. They are responsible for the distinctive smells and flavours of different cultivars — from citrusy and fruity to earthy, piney, or diesel. Beyond aroma, terpenes are widely believed to play a role in shaping the cannabis experience, working alongside cannabinoids in what researchers call the entourage effect.

Myrcene is one of the most common terpenes in cannabis. It has an earthy, musky, slightly fruity aroma and is also found in hops and mangoes. It is often associated with more relaxing, body-focused experiences, though individual responses vary greatly.

Limonene has a bright, fresh citrus aroma — think orange and lemon peel. It is found in citrus fruits and many popular cannabis cultivars. It is often associated with uplifting, mood-elevating experiences. Cultivars high in limonene tend to have a zesty, refreshing scent that is immediately recognisable.

Beta-caryophyllene is a spicy, peppery terpene also found in black pepper and cloves. It is unique among terpenes in that it directly interacts with CB2 receptors in the endocannabinoid system. It is a common terpene across many cannabis varieties and is the subject of growing research interest.

Linalool is a floral, lavender-scented terpene also found in lavender plants. Cannabis cultivars high in linalool often have a soft, calming aroma. It is one of the terpenes commonly discussed in relation to relaxing and stress-reducing experiences, though individual responses differ.

Pinene (alpha- and beta-pinene) smells like pine trees and is one of the most abundant terpenes in the natural world. It is found in pine trees, rosemary, and various cannabis cultivars. It is associated with alertness and is commonly found in more cerebral, uplifting cultivar profiles.

Each cannabis cultivar has a unique combination and concentration of terpenes (and flavonoids) that gives it its distinctive aroma and flavour. Growing conditions, genetics, curing methods, and storage all influence the final terpene expression. This is why two cultivars with similar THC levels can feel and taste completely different.

Many cannabis researchers and experienced consumers believe terpene profiles are a more useful guide to the character of an experience than THC percentage alone. High THC does not always mean a more enjoyable or appropriate experience. At Green Cart, we encourage members to explore terpene education as part of making more informed choices.

Everyone's endocannabinoid system is unique. Factors including body weight, metabolism, tolerance, prior experience, mental state, environment, the specific product, and the method of consumption all influence how cannabis affects an individual. There is no universal response, which is why starting low and going slow is always the recommended approach.

Smoking involves combustion, producing smoke along with cannabinoids and terpenes. Vaping heats cannabis below the combustion point, producing vapour without burning the material. Vaping is generally considered to be less harsh on the lungs and may preserve more of the terpene profile. Both methods produce effects within minutes.

'Set and setting' refers to your mindset (set) and physical environment (setting) when using cannabis. Both significantly influence the experience. A calm, comfortable, familiar environment with a relaxed state of mind generally leads to a more pleasant experience. Stress, unfamiliar surroundings, or social pressure can amplify discomfort or anxiety.

Stay calm — cannabis overconsumption is very uncomfortable but not medically life-threatening. Move the person to a quiet, safe space. Offer water and something light to eat. Encourage slow, steady breathing. Having a calm, trusted person present helps significantly. The feeling will pass. CBD has been anecdotally reported to reduce THC-related discomfort in some cases.

Tolerance is the body's adaptation to regular cannabis use over time, requiring more of a product to achieve the same effect. A break from use — often called a 't-break' or tolerance break — can reset sensitivity. This is a normal physiological response that varies significantly between individuals.

'Greening out' is South African slang for consuming too much cannabis at once and feeling overwhelmed, nauseous, dizzy, or anxious. It is most common in inexperienced users or when someone underestimates a product's potency. It is not medically dangerous but can be very unpleasant. Rest, hydration, food, and calm breathing are the recommended response. Green Cart's education materials address this as part of responsible use.

Start low, go slow is the most widely recommended approach for cannabis — especially for those new to it or trying a new product for the first time. Begin with a very small amount, wait to understand how it affects you, and only increase gradually if needed. This principle is especially important with concentrates like hash rosin and live hash rosin, which are significantly more potent than flower. Green Cart promotes this as a cornerstone of responsible use.

Combining cannabis with alcohol is not recommended, particularly for inexperienced users. Alcohol can significantly intensify the effects of THC and substantially increases the likelihood of nausea, dizziness, and discomfort. This combination is one of the most common causes of 'greening out'.

Yes. Cannabis impairs reaction time, spatial awareness, and decision-making. It is illegal and dangerous to drive under the influence of cannabis in South Africa. Do not drive or operate heavy machinery after consuming any cannabis product, regardless of how you feel. This is non-negotiable.

Signs of degraded cannabis include: a hay or mouldy smell rather than its typical aromatic profile; visible mould or mildew (white or grey fuzzy spots); an unusually dry and crumbly texture; or a complete loss of aroma. Improperly stored cannabis degrades significantly faster in South Africa's warm and sometimes humid climate. Always use airtight, opaque containers.

Cannabis can interact with certain medications. If you are on any prescription medication, consult your registered South African medical practitioner before using cannabis. This applies to blood thinners, antidepressants, sedatives, and several other medication types. Do not guess on this — it is an important health and safety consideration.

Green Cart recommends the following: Only consume if you are 21 or older (or as directed by a medical practitioner). Do not consume in public spaces. Never drive under the influence. Keep cannabis securely stored away from children and pets. Know what you are consuming and its approximate potency before you begin. Consume in a safe, comfortable, private environment. Respect those around you.
