What is MR3 CBD Flower?

MR3 is a hybrid hemp variety (Cannabis sativa L.), grown indoors under fully controlled conditions. Born from an indoor selection, it develops dense, resinous buds with fine consistency from one batch to the next, characteristic of controlled-environment cultures.

This CBD flower contains 13.5% CBD (sum of CBD + CBDA, chromatography analysis) and a Δ9-THC content of 0.13%, in line with European regulations: no psychoactive effects are to be expected. Indoor cultivation under light, temperature and humidity controlled 24/7 concentrates trichome density and preserves the variety’s aromatic purity. Common terms used in the industry: CBD flower, hemp flower, CBD bud, legal hemp CBD, CBD cannabis.

Aroma profile: balanced, sweet and resinous

MR3 releases a balanced, soft fragrance on first contact, carried by a lightly sweet note over a clean resinous base. An accessible, versatile profile without excess, suited to a wide range of consumers looking for a quality indoor flower with a clear character.

From a terpene perspective, this aroma profile is driven by myrcene (soft, resinous base), beta-caryophyllene (spicy touch), limonene (freshness) and alpha-pinene (green clarity). These terpenes act in synergy with cannabinoids in what scientific literature calls the ‘entourage effect’, characteristic of full-spectrum hemp extracts.

How to use MR3 CBD Flower?

Given the CBD content of 13.5%, those new to CBD flower are advised to start with small amounts and increase gradually based on their individual response. For adult use only. Thanks to its balanced profile, MR3 is well suited for both daytime and evening use.

• Vaporisation (recommended method): Use a convection or conduction vaporiser set between 170 and 185 degrees Celsius for optimal terpene and cannabinoid extraction without combustion.
• Herbal infusion: Steep the crumbled buds in a fat-containing liquid (whole milk, plant milk, or butter) for 10 to 15 minutes at a maximum of 85 degrees Celsius to preserve the terpene profile.
• Cooking: Decarboxylate first at 110 degrees C for 30 minutes, then incorporate into a fat-based recipe. Suggested dosage: start with 0.5 g per adult serving.

Vaporisation is the most considerate method of consumption: it avoids combustion entirely and preserves the full aroma profile of MR3.

How to store MR3 Indoor CBD flowers?

Store in an airtight container (glass jar or resealable pouch) away from direct light, in a cool and dry place. Optimal shelf life: 6 months after opening. Keep out of reach of children and pets.

CBD flower legal framework

CBD hemp flowers (Cannabis sativa L.) with a THC content of less than 0.3% are legally marketable across the European Union. The Court of Justice of the EU ruled in the Kanavape case (C-663/18, 19 November 2020) that CBD products derived from the whole hemp plant can move freely within the EU. MR3 CBD flowers may also fall under the EU Novel Food Regulation when used as a food supplement. The Δ9-THC content of batch MRIND-0126 is 0.13%, as independently verified by laboratory analysis.

The MR3 Indoor CBD Flower is carefully selected and independently analysed by the 321CBD team, which has been active since 2018, before being made available on 321CBD.com.
