🌿 Auto CBD Charlotte's Web Seeds — The High-CBD Classic on a Fixed Timeline

Auto CBD Charlotte's Web seeds carry the high-CBD, near-zero-THC genetics of the Stanley Brothers' CBD Charlotte's Web strain on a fixed 63–70 day seed-to-harvest timeline that flowers automatically without a light schedule change. CBD Charlotte's Web was developed in Colorado from a specific high-CBD phenotype of industrial hemp — a cross between a marijuana plant and a hemp strain selected for its unusually high CBD content and near-zero THC. The strain produces 15–20% CBD with THC below 1%, placing it firmly in the hemp category for potency and producing none of the psychoactive effect associated with THC-dominant cannabis.

The origin: CBD Charlotte's Web was developed by the Stanley Brothers in Colorado after selectively breeding a hemp cross for high CBD and near-zero THC. The strain became widely known following documented use with Charlotte Figi, a child with a severe seizure disorder, which drew global attention to high-CBD, near-zero-THC cannabis and accelerated the broader CBD wellness movement. It remains the most recognised high-CBD strain in the world and the reference point for the entire category.

What Auto CBD Charlotte's Web seeds are: A high-CBD, non-psychoactive autoflower for growers who want CBD-rich material on a fixed, predictable timeline. The Ruderalis cross preserves the core CBD Charlotte's Web CBD profile — the subtle herbal and pine terpene character, the high-CBD low-THC ratio — while adding the fixed-timeline autoflowering trait. 63–70 days from seed to harvest regardless of light schedule, compact at 60–100 cm, suitable for indoor or outdoor cultivation.

What Auto CBD Charlotte's Web seeds are not: A high-THC strain. The experience is non-intoxicating at typical doses — no psychoactive effect, no altered mental state. If you're looking for THC-dominant genetics, every other auto in the catalogue is that. This strain is specifically for growers who want high-CBD, near-zero-THC material.

What Auto CBD Charlotte's Web seeds do well:

• High-CBD, near-zero-THC profile: 15–20% CBD with <1% THC — the defining characteristic that made CBD Charlotte's Web genetics significant. Consistent across the auto version
• Non-psychoactive: No THC-induced altered state. Clear-headed throughout, regardless of dose
• Fixed timeline: 63–70 days seed to harvest on any light schedule — one of the faster auto timelines in the catalogue
• Subtle terpene profile: Herbal, pine, and earthy — less pungent than THC-dominant autos, which suits lower-profile grows
• Multiple outdoor cycles: The short 63–70 day timeline allows three to four complete outdoor runs per Australian season in warm states

🌿 What We Love About Auto CBD Charlotte's Web Seeds

The CBD-to-THC ratio is the defining thing. At 15–20% CBD and under 1% THC, Auto CBD Charlotte's Web seeds produce material that's categorically different in effect from every other auto in the catalogue — non-intoxicating, clear-headed, and functional at any time of day. For growers who specifically want high-CBD, near-zero-THC material, there isn't a comparable option.

The terpene profile is subtle in a way that's genuinely useful. Most cannabis autos announce themselves with pungent diesel, skunk, or sweet fruit odours. Auto CBD Charlotte's Web seeds produce a herbal, pine, and earthy profile that's pleasant without being conspicuous — an advantage for home grows where strong cannabis odour is a concern. The herbal-pine character comes from the pinene and myrcene terpenes that dominate the profile.

The fixed 63–70 day timeline is among the shortest in the auto catalogue. Three to four complete outdoor cycles per season are achievable in warm Australian states. For growers who want high-CBD material on a rolling, predictable schedule rather than committing to a single long photoperiod run, the auto format makes consistent production practical.

🌿 Auto CBD Charlotte's Web Effects & Experience

What to expect — non-psychoactive: Auto CBD Charlotte's Web seeds produce no psychoactive effect at <1% THC. There is no altered mental state, no "high," no impairment of cognitive function or reaction time. This is the defining characteristic of this strain and the primary reason growers choose it over THC-dominant genetics.

What CBD cannabis is commonly sought for: Auto CBD Charlotte's Web seeds are grown primarily by those specifically seeking non-psychoactive, CBD-rich cannabis. Within the CBD wellness community, high-CBD near-zero-THC cannabis is widely valued for daytime use — sought after by those who want the perceived benefits of cannabis without any THC-induced psychoactive effect. Common contexts include daytime supplementation, use in professional environments, personal wellness routines, and situations where clear-headedness is required throughout. It's also the strain of choice for those who react poorly to THC or who specifically avoid it for lifestyle, professional, or personal reasons. The non-psychoactive nature at any dose is the core characteristic that makes CBD Charlotte's Web genetics distinct from every other strain in the catalogue.

What CBD does produce: A calm, settled physical quality that's difficult to attribute precisely to any single mechanism — the effect profile of high-CBD cannabis at functional doses. Reduced physical tension. A general sense of ease that doesn't impair clear thinking. The pinene component supports mental clarity and alertness; the myrcene component contributes a calming physical background; the linalool adds mild sedative quality at higher doses; the caryophyllene adds anti-inflammatory character directly at the tissue level.

Onset: 15–30 minutes. Subtle — nothing like the fast onset of THC-dominant autos. The effect builds gradually.

Duration: 3–5 hours at typical doses. Longer than most THC-dominant auto experiences given the different metabolic pathway of CBD.

Flavour profile: Herbal and fresh pine on the inhale with earthy undertones. Clean and subtle on the exhale. Not the sweet, diesel, or skunky profiles that characterise most of the auto catalogue. Pleasant and mild. Proper cure for 2–3 weeks improves the herbal-pine complexity.

🌱 Growing Auto CBD Charlotte's Web Seeds — Complete Guide

(The following is provided for ACT licence holders and growers in legal jurisdictions overseas.)

Experience level required: Accessible. Auto CBD Charlotte's Web seeds are among the more forgiving genetics in the auto catalogue — the hemp-influenced Ruderalis component adds resilience, and the lower potency ceiling means minor feeding errors don't compound the way they do with high-THC genetics. The standard auto rules still apply: final container from day one, no transplanting, conservative early feeding, LST only.

Critical auto rules — before germination:

• Start in the final container. 10–15 L indoors, 15–20 L outdoors. No transplanting
• No transplanting. Non-negotiable for all autos
• Feed at 1/4 strength from week one. CBD plants are lighter feeders than THC-dominant autos — excess nitrogen particularly affects the herbal terpene profile
• LST only. Gentle LST from week 2–3. No topping

Flowering: Auto CBD Charlotte's Web seeds initiate flowering at 3–4 weeks from germination. Seed to harvest runs approximately 63–70 days — one of the shorter timelines in the auto catalogue. The CBD harvest window is different from THC autos and requires specific attention.

CBD harvest timing — critical difference from THC autos: CBD content peaks and then declines as trichomes develop further. For maximum CBD, harvest when trichomes are mostly cloudy with minimal amber — around 5–10% amber at most. Waiting for the 15–25% amber target appropriate for THC-dominant autos results in lower CBD content as the compound degrades. Check trichomes from day 56.

Height and structure: Compact at 60–100 cm. Well-branched with dense bud sites for a CBD strain. LST from week 2–3 opens the canopy and improves light penetration. The more open sativa-influenced structure manages airflow well.

Aroma during grow: Notably less pungent than THC-dominant autos. The herbal-pine profile remains subtle throughout — carbon filtration is still recommended indoors from week 5 but the smell is more manageable than most of the catalogue.

Common issues: Overfeeding (CBD plants are lighter feeders than THC autos — excess nitrogen is more common with these genetics), harvesting too late (CBD degrades with advancing amber trichomes — harvest earlier than you would with THC-dominant genetics), rushing the cure (the subtle herbal-pine terpene character develops in the jar over 2–3 weeks).

🏠 Indoor Growing (Australia)

• Seed to harvest: 63–70 days fixed — no light flip required. Flowers on any schedule
• Yield: Up to 450 g/m² under quality lighting with LST
• Container: Start and finish in 10–15 L — no transplanting
• Light schedule: 18/6 recommended. 20/4 marginally better for yield. No 12/12 flip required — this is an autoflower
• Height: 60–100 cm — fits standard tent heights comfortably
• Training: LST from week 2–3. More forgiving than high-THC sensitive genetics
• Harvest timing: Mostly cloudy trichomes, 5–10% amber maximum — earlier than THC autos for peak CBD
• Cycles per year: 5–6 complete indoor runs annually with the 63–70 day timeline
• Aroma: Subtle herbal-pine from week 4–5 — less pungent than THC-dominant autos. Carbon filtration still recommended

🌿 Outdoor Growing (Southern Hemisphere / Australia)

• Harvest timing: ~63–70 days from planting — not season-dependent
• Yield: 100–200 g per plant — larger containers (15–20 L) and full sun push toward the upper end
• Container: 15–20 L minimum — start in the final pot, no transplanting
• Site: Full sun preferred. 6+ hours direct light minimum
• Multiple runs: Three to four outdoor runs per Australian season achievable with the 63–70 day timeline — September, November, January, and March plantings viable in warm states
• Climate suitability: The hemp-influenced Ruderalis genetics handle a wide range of Australian conditions. More resilient to temperature variation than high-THC sensitive genetics. Handles heat well
• Aroma outdoors: Subtle herbal-pine profile — less conspicuous than THC-dominant autos in outdoor positions

🧪 Auto CBD Charlotte's Web Seeds EC & Feeding Guide — Soil and Coco

Auto CBD Charlotte's Web seeds are lighter feeders than THC-dominant autos — the hemp-influenced genetics have lower nutrient requirements and are more sensitive to overfeeding, particularly excess nitrogen in flower. The herbal and pine terpene profile also benefits from conservative nitrogen throughout the grow and a proper flush before harvest. Start at 1/4 strength and build conservatively. The CBD-specific harvest window (mostly cloudy, minimal amber) means the feeding and flush schedule runs slightly shorter than with THC-dominant autos.

All EC values assume quality base nutrients. Australian tap water typically runs 0.2–0.5 EC — factor this into your target. Measure after mixing.

📊 EC & pH Target Table — Soil vs Coco

🌱 Soil-Specific Notes

Pre-loaded nutrients: Quality potting mix runs 1.0–1.5 EC on its own in weeks 1–3 — above the target EC for CBD Charlotte's Web in those weeks. Plain water for the first 1–2 weeks in pre-loaded soil. Feed only when runoff EC drops below 0.6 for this strain.

Runoff monitoring: Water to 10–20% runoff and measure EC. The lower EC ceiling throughout the grow means salt buildup can occur more quickly relative to the feed-in target. Flush with 2× pot volume plain pH water when runoff EC runs 0.4+ above feed-in.

Watering frequency: Every 2–3 days in veg, every 1–2 days in flower. Allow the top 2–3 cm to dry between waterings.

🥥 Coco-Specific Notes

Feeding frequency in coco: Once daily in veg, once to twice daily in flower. The lower EC ceiling means consistent small feeds rather than pushing higher concentrations.

pH in coco: 5.9–6.1 at every feed. The herbal-pine terpene profile is sensitive to pH drift. Check every feed.

CalMag in coco: 1 ml/L CalMag from week 1 through flush. Standard coco CalMag supplementation applies — the CBD genetics don't change this requirement.

Lower EC ceiling note: Auto CBD Charlotte's Web seeds run noticeably lower EC than THC-dominant autos throughout the grow. Growers who switch from high-THC to high-CBD genetics and apply the same feeding approach consistently overfeed. The peak flower EC ceiling (1.2–1.6 in coco) is lower than what most THC autos can handle — respect this difference.

📋 EC Troubleshooting — Auto CBD Charlotte's Web Seeds

💡 Feeding Key Principles — Auto CBD Charlotte's Web Seeds

• Lower EC ceiling than THC-dominant autos throughout: Don't apply THC auto feeding rates to these genetics — the hemp-influenced CBD plant has lower nutrient requirements and is more sensitive to excess feeding
• CBD production is genetic, not feeding-dependent: Pushing higher EC doesn't increase CBD percentage — it risks tip burn and terpene damage. Feed conservatively and let the genetics do their work
• Harvest timing overrides flush duration: If trichomes are approaching 10% amber and the flush isn't complete, harvest rather than waiting. CBD degrades with advancing amber — the harvest window is earlier and narrower than with THC-dominant genetics
• Flush and cure for terpene quality: 7 days flush until runoff drops below 0.5, then 2–3 weeks in sealed jars. The herbal-pine character of CBD Charlotte's Web develops during cure

🗓️ Auto CBD Charlotte's Web Seeds — Week-by-Week Grow Guide

Auto CBD Charlotte's Web seeds run 63–70 days — one of the shorter auto timelines in the catalogue. The critical difference from THC-dominant autos is the harvest window: CBD peaks at mostly cloudy trichomes and declines as amber develops. The week-by-week timeline reflects this earlier harvest target.

🌿 Is Auto CBD Charlotte's Web Right for Your Grow?

❓ Frequently Asked Questions — Auto CBD Charlotte's Web Seeds

🌿 What is Auto CBD Charlotte's Web?

Auto CBD Charlotte's Web seeds are an autoflowering feminised version of the Stanley Brothers' CBD Charlotte's Web high-CBD strain — crossed with Ruderalis genetics to flower automatically at 3–4 weeks from germination regardless of light cycle. The strain produces 15–20% CBD with THC below 1%, placing it firmly in the hemp potency category. Seed to harvest runs 63–70 days on a fixed timeline. The defining characteristic is the near-zero-THC, high-CBD profile — non-psychoactive at any dose.

⏱ How long do Auto CBD Charlotte's Web seeds take from seed to harvest?

Approximately 63–70 days (9–10 weeks) from germination — one of the shorter auto timelines in the catalogue. Harvest at mostly cloudy trichomes with 5–10% amber maximum. This is earlier than the amber targets appropriate for THC-dominant autos. CBD content peaks before significant amber develops and declines from there — the harvest window is narrower and earlier than most growers expect coming from THC-dominant genetics.

🔥 Does Auto CBD Charlotte's Web produce any psychoactive effect?

No. At <1% THC the strain produces no psychoactive effect regardless of dose. CBD interacts with the endocannabinoid system through different mechanisms than THC. If you're looking for a "high," this is not the right strain — every other auto in the catalogue produces THC-dominant psychoactive effects. This strain is specifically for growers who want high-CBD, non-intoxicating material.

🌾 What yields can I expect from Auto CBD Charlotte's Web seeds?

Up to 450 g/m² indoors under quality lighting with LST. In practice, 350–400 g/m² is a realistic expectation for dialled grows — CBD hemp genetics generally run slightly lower practical yields than optimised THC auto genetics under equivalent conditions. Outdoor plants produce 100–200 g each, with 15–20 L containers and full sun pushing toward the upper end. The 63–70 day timeline allows five to six indoor runs annually, which changes the per-year production equation significantly.

🌱 Is Auto CBD Charlotte's Web suitable for first-time growers?

Yes — one of the more accessible autos in the catalogue. The hemp-influenced Ruderalis genetics add resilience to minor cultivation inconsistencies. The standard auto rules still apply (final container from day one, no transplanting, light early feeding), but the lower-stakes potency profile means minor errors don't compound the way they do with high-THC sensitive genetics. The main adjustment for growers coming from THC-dominant autos is the lower EC ceiling and the earlier harvest window.

🌞 How many outdoor harvests per season in Australia?

Three to four harvests per Australian season in warm states. Plant September, harvest November. Plant November, harvest January. Plant January, harvest March. The 63–70 day fixed timeline makes planning straightforward. Queensland and Northern NSW growers get the most benefit from multiple-cycle outdoor production with this strain. The subtle herbal-pine aroma, which stays less pungent than THC-dominant autos throughout the grow, is an additional advantage for outdoor positions.

💧 How is feeding Auto CBD Charlotte's Web seeds different from THC-dominant autos?

Two key differences. First, the EC ceiling is lower throughout the grow — CBD plants are lighter feeders than THC-dominant autos. Applying THC auto EC targets to this strain consistently overfeeds it. Second, back off nitrogen from week 5 (earlier than most THC autos) — the herbal terpene profile suffers with excess nitrogen in late flower. The harvest timing is also different: harvest at mostly cloudy trichomes with 5–10% amber maximum, not the 15–25% amber target appropriate for THC-dominant genetics.
