What CBD Flower is

CBD flower is the dried inflorescence of an industrial hemp plant. The buds contain the plant’s cannabinoid and terpene profile, concentrated in the trichomes coating the calyxes. This is where the CBD content is found, alongside the aromatic compounds that give each variety its distinct profile. All Justbob hemp comes from EU growing partners working with Cannabis sativa L. genetics from the European Common Catalogue, with THC verified daily under the 0.3% EU-harmonised threshold.

The format is straightforward: hemp flowers, dried and cured, ready to be added to your collection. The catalogue above features more than 30 varieties, grown using three different cultivation methods. CBD levels range from roughly 15% in the entry-level Greenhouse line to over 60% on the Boost-derived Indoor varieties. Every batch is lab-tested before being included in the catalogue, ensuring consistency and quality across all products.

Hemp inflorescence with high CBD content

Hemp flowers come from female Cannabis sativa L. plants, grown specifically for high-CBD expression. Male plants produce only seeds and pollen, so the cultivars on the catalogue are seedless feminised genetics selected for their cannabinoid profile and terpene signature. The trichomes that cover the calyxes are tiny resin glands, and their density and integrity decide how much of the cannabinoid load reaches the final bud.

The key difference between a high-CBD variety and a high-THC strain lies in the cannabinoid ratio. Standard high-THC cannabis contains THC levels well above the 0.3% threshold. In contrast, the CBD flowers in our catalogue are the opposite, with CBD as the dominant cannabinoid and THC kept under the EU-harmonised limit. While they come from the same plant species, differences in genetics and cultivation processes lead to very different cannabinoid profiles. This distinction is also what defines CBD flower in Europe as a clearly recognised category within EU hemp regulations.

Our 30+ CBD flower varieties at a glance

The current catalogue includes more than 30 varieties, split across Indoor, Glasshouse, Greenhouse, Sieved and Trim formats. Each variety is hand-finished at our EU production sites and lab-tested before being listed in the catalogue.

Indoor selections

The Indoor tier includes varieties grown under controlled lighting, ventilation and feed schedules. BUBBLEGUM, CALIFORNIA HAZE, HQ CBD BOOST, DOUBLE COOKIES, MANGO CBD BOOST, ORANGE CBD BOOST, OG SUPER BOOST and AK47 CBD BOOST all belong to this tier. Indoor flowers offer the most intense visual signature: tight calyxes, intact crystalline trichome coverage, predictable batch-to-batch consistency. This is where customers come for the highest cannabinoid content per gram.

The Indoor tier covers the broadest CBD content range on the catalogue, from around 19% on classics like Double Cookies and Gorilla #44 up to 60% on OG Super Boost. Lab analysis routes the high-CBD varieties through a longer curing window before they reach the listing.

Glasshouse and Greenhouse selections

The Glasshouse tier, where the crops are grown in a glass enclosure under both natural and artificial light, includes GELATO CBD BOOST, GG#4 CBD BOOST, AMNESIA CBD BOOST, SWEET BERRY, ZKITTLES CBG, WHITE WIDOW, CRITICAL SUPER BOOST and SUPER SKUNK. Glasshouse flowers carry a more rounded aromatic profile compared to Indoor, with terpenes that develop over a longer flowering window.

The Greenhouse tier is grown under natural light with controlled temperature and humidity. It includes MASTER KUSH, MELON KUSH, LEMON CHEESE, SMALL BUDS MIX, ALPINE CBG SMALL BUDS, BLUEBERRY SMALL BUDS and the OUTDOOR MIX. These represent the most accessible per-gram options in the catalogue, with CBD content typically ranging between 15% and 30%. The format also includes Sieved and Trim variants for shoppers looking at smaller calibres.

Cultivation methods: Indoor, Greenhouse, Glasshouse

Most of the catalogue is structured around three cultivation methods, each delivering its own characteristics in the final flower. Choosing between them comes down to your priorities: cannabinoid density, aromatic complexity, or per-gram price.

Indoor: controlled conditions and high CBD content

Indoor cultivation runs in controlled grow rooms under LED lighting, carefully managed ventilation, and structured feeding schedules. The photoperiod follows a standard 18 hours of light and 6 of darkness during the vegetative phase, then shifts to 12 and 12 in flowering. Nutrient EC starts at 1.2 mS/cm at the beginning of the cycle, gradually increasing up to 2.0 mS/cm at peak flowering, before tapering back to around 1.3 mS/cm toward the end, with a late-stage calcium-magnesium feed. Temperature is maintained between 20 and 26 degrees Celsius, while humidity stays within a range of 40% to 60%.

The result is the densest cannabinoid expression in the catalogue. Indoor flowers carry tight calyxes, intact crystalline trichomes and a predictable batch-to-batch profile. The energy required for indoor production is significant, which is why these varieties sit at the top of the per-gram price ladder.

Greenhouse and Glasshouse: natural light with controlled environment

Greenhouse cultivation uses natural sunlight to drive the photoperiod, with temperature and humidity controlled artificially. Greenhouse flowers carry a more rounded aromatic profile than Indoor, with terpenes that develop over a longer flowering window. The growing cycle allows two to three flowering windows per year, depending on latitude.

Glasshouse cultivation sits halfway between Indoor and Greenhouse. The crop grows in a glass enclosure that combines natural sunlight with artificial light supplementation, plus full climate control. The format produces flowers throughout the year, with a profile that blends the cannabinoid density of Indoor with the aromatic complexity of Greenhouse. Most of our high-CBD Boost varieties grow under Glasshouse conditions.

Classic genetics: White Widow, California Haze, Gorilla #44, Amnesia

The catalogue features many of the classic hemp genetics that European CBD shoppers will recognise by name. Each strain has its distinct terpene profile and aroma, with the high-CBD version sourced from EU growers under the 0.3% THC threshold.

Here is a quick overview of what is included:

• WHITE WIDOW: a Glasshouse variety featuring the classic terpene profile of the original Greenhouse Seeds genetics from the Netherlands (mid-1990s), with crystalline trichome coverage and a balanced aromatic signature.
• CALIFORNIA HAZE: an Indoor classic based on the original Haze lineage selected in California in the 1970s, offering citrus and pine on the terpene profile.
• GORILLA #44 (high-CBD echo of the Gorilla Glue lineage): an Indoor variety known for the dense resin coverage that made the original GG#4 famous.
• AMNESIA CBD BOOST: the Amnesia Haze lineage cultivated under Glasshouse conditions, with the cannabinoid levels enhanced through our patented Boost enrichment route.
• CRITICAL SUPER BOOST: a cross of Big Bud and Skunk #1, with the cannabinoid concentration increased by our Boost protocol.
• AK47 CBD BOOST: derived from the original AK-47 lineage (Serious Seeds, 1992), grown Indoor and enhanced using the patented Boost enrichment route for higher cannabinoid expression.

When to pick each variety

The choice of variety depends on what you are looking for. White Widow, California Haze and Bubblegum are natural starting points for shoppers new to the catalogue, offering classic terpene profiles, a balanced cannabinoid load, and more accessible per-gram pricing. Critical Super Boost, OG Super Boost and AK47 CBD Boost sit at the top end of the catalogue, featuring the densest cannabinoid expression. Lemon Cheese, Sweet Berry and Blueberry Small Buds cover the fruiter, more aromatic side of the range.

For the pressed-format counterpart of the same genetics, see our CBD hash page, where the resin-sieved versions of several Indoor and Glasshouse flowers are listed. The selection at the top of this page shows the current Indoor, Glasshouse, Greenhouse and Sieved range, with live prices and lab-tested cannabinoid content for each batch.

Quality, certificates and EU compliance

Every hemp flower batch undergoes the same lab analysis routine as the rest of the Justbob catalogue, with samples sent to independent EU-certified laboratories on a daily basis. The cannabinoid profile (CBD, CBG, THC content) is measured for each batch, and the results are recorded in a certificate of analysis which is kept on file.

The hemp comes from selected EU partners working under organic cultivation standards, with strict controls for pesticide residues, heavy metal contamination and any GMO presence at every step. The THC content stays under the 0.3% EU-harmonised threshold defined by Regulation (EU) 2021/2115 and the Common Catalogue of agricultural plant varieties, and it is verified daily before the batch reaches our facility.

THC under 0.3% and COA on request

The legal status of our hemp-derived CBD flower is grounded in the European framework. The Court of Justice of the European Union confirmed, in the Kanavape ruling of November 2020, the principle of free movement within the European Union for hemp-derived CBD products that comply with the harmonised threshold. CBD is currently classified as a novel food in the European Union, which is why our cbd flowers catalogue is sold for technical, scientific, ornamental and collector purposes.

If you would like the certificate of analysis for a specific batch, feel free to contact us at info@justbob.shop and we will send it across. The COA shows the cannabinoid breakdown, THC verification, and the batch identifier for full traceability. All certificates are also archived for several years after shipment.
