CBD #1 Feminized stands within the ACE Seeds catalog as a masterpiece of modern breeding entirely dedicated to medical users and lovers of noble aromatic profiles free from disabling psychotropic effects.
This variety is the result of a stabilized hybridization between the award-winning Erdpurt (100% indica Alpine Hash Plant) and the famous Cannatonic, one of the mother lines that revolutionized the global medical cannabis scene.
Agronomically, this cross produces remarkably compact, robust, and fast plants, capable of synthesizing an imposing amount of cannabidiol while keeping THC safely below psychotropic tolerance thresholds.
CBD #1 is an indica-dominant hybrid (70% Indica / 30% Sativa) celebrated for its unique cannabinoid profile shifted heavily in favor of CBD, showing CBD levels between 13% and 17% against a THC content consistently below 1% (0.6-0.7%).
With an ultra-fast indoor flowering time of just 55-65 days (8-9 weeks), it develops dense, resinous, and geometric buds, showcasing an aromatic profile dominated by notes of tangerine, fuel, and wet earth.
It delivers a stable indoor yield of 400 – 500 g/m² and manifests an exceptional tolerance to cold and pests.
Phylogenetic records preserved in the Seedfinder database confirm that CBD #1 was conceived by ACE Seeds to satisfy the increasing demand for pure CBD strains.
The Erdpurt input stabilizes the structure, enhances resinous secretion, and shortens Cannatonic’s flowering times, providing the lineage with unparalleled cold resistance.
“A biochemical pillar that converts photosynthesis into pure physical well-being, excluding psychotropic cerebral activity.”
In technical analyses tracked on ICMag forums, this variety is highly praised for the incredible stability of its chemotype. Unlike many commercial CBD hybrids that show wide variations in cannabinoid ratios, CBD #1 guarantees a consistent ratio higher than 20:1.
This technical aspect is fundamental for medical patients who demand standardized treatments free from anxiety-inducing THC side effects.
In controlled grow rooms, CBD #1 Feminized proves to be a compact, stocky, and highly predictable plant, great for those with limited vertical space or micro-growboxes.
It shows a very contained vertical elongation rate (stretch) after the hormonal switch (around 50-80%), which is why it is advisable to grant it a robust vegetative phase of at least 4-5 weeks before setting the flowering cycle to 12 hours of light and 12 hours of darkness.
It expresses its maximum production potential when grown using the Sea of Green (SOG) technique, matching its natural columnar structure. The VPD parameter must be maintained between 1.1 and 1.4 kPa.
Nutrient absorption is moderate: thanks to the efficiency inherited from Erdpurt, it does not tolerate intense mineral overfeeding. It is recommended to stabilize the maximum electroconductivity (EC) between 1.3 and 1.5 during peak flowering to prevent salt buildup in the substrate.
Outdoors, this variety shows exceptional survival skills in cold, humid, and high-latitude climates (up to Northern Europe). The root system is robust and responds with great vigor to early mycorrhizae inoculation.
Maturation concludes early between late September and the first days of October in the northern hemisphere, allowing for the harvest of healthy and solid buds well before the arrival of chilling autumn rains.
Resistance to botrytis is excellent, facilitated by a thick leaf cuticle and a protective waxy coating. Under the influence of night cold, many specimens develop spectacular purple and bronze hues on the flowers.
The biochemical profile of CBD #1 stands out for an extraordinary richness and olfactory complexity, inherited both from Cannatonic’s citrus notes and Erdpurt’s resinous background. The bouquet is dominated by high fractions of Beta-Myrcene and Terpinolene.
Primary notes recall tangerine peel, sweet orange, and tropical fruits, balanced by a dense background of fuel, organic incense, and wet earth. During the curing phase (which requires a minimum of 8 weeks in jars), chemical undertones merge into a creamy and velvety aroma.
For extraction technicians, this variety represents an elite choice: trichome density ensures high yields in the production of medicinal extracts, full-spectrum therapeutic oils, and hot-pressed Rosin, keeping the fruity aroma perfectly intact.
Based on medical data and user reviews on platforms like Leafly, the action of CBD #1 is purely physical and completely free from psychotropic activity or time-perception alterations.
With a THC content below 0.7%, the cerebral effect is null: the mind stays clear, active, and perfectly functional for high-precision daily tasks.
On the physical level, the interaction between the high CBD level and CBG generates an immediate feeling of muscle relaxation, diffused warmth, pain reduction, and emotional stress relief.
It is a genetic line traditionally associated with anxiety relief, muscle inflammation, and functional daytime medical use. Great for consumers who wish to enjoy the flavor and ritual of smoking without undergoing psychedelic effects or the mental lethargy typical of high-THC cannabis.
Pure Cannatonic frequently presents unstable phenotypes with 1:1 ratios or high THC levels that require laborious selection. CBD #1 by ACE Seeds introduces Erdpurt genes, stabilizing the pure CBD ratio (20:1), shortening flowering, and increasing bud compactness.
Pure Erdpurt is a 100% indica alpine hash plant with a mostly therapeutic profile but lower CBD levels (6-12%) and earthy/coffee aromas. CBD #1 increases the CBD percentage up to 17% and introduces Cannatonic’s sweet, citrusy tangerine notes.
Solodiol is a commercial sativa-dominant hybrid developed for light industrial markets. CBD #1 offers a much more compact structure, a true hash plant resin density, and a significantly more complex, persistent, and noble terpene profile.
This genetic line is totally discouraged for commercial growers looking exclusively for maximum volumetric yields of raw weight for industrial textile purposes or those operating hydroponically with very high salt conductivity.
It is unsuitable for recreational consumers looking for devastating cerebral highs, psychedelic effects, or disabling THC levels far from therapeutic use. Furthermore, it is not indicated for those who prefer purely synthetic or artificial aromatic profiles typical of contemporary US Cali quality.
CBD #1 produces buds with THC below 1%, but for European industrial hemp regulations (0.3% limit) it is considered a medical/collectible genetics and not a certified industrial hemp strain.
Classic 18/6 is recommended for the vegetative phase and switching to 12/12 to induce flowering.
Yes, if night temperatures in the grow room drop to around 15-17°C during the final three weeks of bloom, Erdpurt genes stimulate the appearance of beautiful purplish and bronze tones.
The profile highlights dominant peaks of Beta-Myrcene and Terpinolene, followed by significant fractions of Limonene and Alpha-Pinene.
Yes, clones root with excellent vigor, usually within 10-12 days in an environment with controlled humidity and temperature.
CBD #1 Feminized by ACE Seeds Genetics represents the excellence of modern therapeutic breeding, where biochemical stability meets the nobility of old-school hash plants
. We do not recommend it to those looking for a classic recreational high, but to the demanding grower or medical patient who requires an elite biomass, rich in CBD and completely free from mental psychotropic effects.
Its extraordinary cold resistance, late-September outdoor flowering speed, and a flow of tangerine and gas resin that matches recreational Cali quality, position it as one of the best pure medicinal strains available on the international market.
