How to Grow CBD White Widow Autoflower
CBD White Widow Autoflower turns the frosty, legendary White Widow into a high-CBD, easy-growing auto. This version is bred to lead with CBD rather than THC, pairing a mellow 10–12% CBD with a low 6–7% THC, and it runs from seed to harvest in just 8–10 weeks whatever the season.
It comes from crossing White Widow with a CBD-rich parent and Ruderalis. That cross keeps the resin, frost and citrus-sweet character of the original White Widow while adding both the high-CBD trait and the autoflowering habit, so the plant flowers on age rather than on any change in the light.

Climate and Where to Grow It
CBD White Widow Autoflower is happiest in a warm, tropical climate with plenty of light and heat. It takes the sun well and keeps growing through conditions that would stall a cooler-climate plant, which is part of why it is such an easy auto to run outdoors in the right spot.
The flip side of tropical heat is humidity, and that is the one thing to stay on top of. White Widow genetics build dense, frosty, resin-coated buds that trap moisture, so you want strong airflow and a close eye on humidity through flowering to keep bud rot and mould away. A breezy, open canopy and a dehumidifier or a fan indoors make a real difference as the colas fatten up.
Indoors, aim for daytime temperatures around 75–82°F (24–28°C) to mimic its tropical comfort zone, and bring the humidity down steadily as the plant moves into bloom. It reaches a moderate 1.5 m, so it fits most tents without much height management, though a little space between plants always helps the air move.
Autoflower Growing Basics
With any autoflower, the golden rule is that you never switch the light schedule to trigger flowering. CBD White Widow Auto starts to bloom by itself at around 3–4 weeks of age, so run a long day of 18–20 hours of light from seedling right through to harvest and leave it there.
Start the seed directly in its final pot, because autos run on a fixed internal clock and resent transplanting, and a short-cycle plant cannot make up growth it loses to a mid-run move. Keep any training gentle too: the vegetative window is brief, so favour low-stress training over heavy topping, tucking and tying branches to open the canopy and let light reach the lower buds. These are the same easy habits that put it among our high-CBD autoflowers that suit first-time growers.
Feeding Schedule (EC Guide)
Autoflowers are light feeders, so start low and build up only as the plant asks for more. The EC values below follow the life-cycle stages rather than a separate veg-to-bloom switch, which keeps feeding simple on a short, continuous run.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Weeks 2–4, raise nitrogen gently |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while buds swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Life Cycle and Harvest
The full life cycle runs 8–10 weeks from seed to harvest. As an autoflower you harvest when the plant tells you it is ready rather than on a fixed calendar date, so let the trichomes be your guide instead of counting from a light flip.
Expect vegetative growth in weeks 1–3, the automatic switch to flower around weeks 3–4, then bud stacking and resin build through to week 8–10. The 60% sativa lean keeps the structure a touch airier and taller than a pure indica, while the White Widow heritage frosts the flowers heavily. Harvest when most trichomes are cloudy with a few turning amber for the fullest CBD expression, and give the plant a 1–2 week plain-water flush before you cut. Because it is an all-season auto, you can time your start date so the finish lands whenever suits you.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. With buds this dense and resinous, a slow, steady dry is important so the inside does not stay damp while the outside dries out.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure sharpens the citrus-sweet aroma and smooths the smoke, and with a CBD-rich strain it also helps the gentle, well-rounded character come through cleanly.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Like its White Widow parent, this is a frosty, resin-heavy plant, so the trim is excellent for dry sift, bubble hash or rosin, giving you a bonus CBD-rich concentrate from material most growers throw away.
Flavor and Terpenes
CBD White Widow Autoflower tastes citrus, fruity and sweet, a bright, lively profile that carries the zing of its White Widow lineage. It is a more cheerful aroma than the earthy, hashy CBD strains, with a clean citrus-sweet lift on the inhale and exhale.
Four terpenes shape it. Terpineol brings soft floral and lilac notes with a hint of citrus; gamma-terpinene adds a mild, zesty citrus and herbal edge that leans into the fruity-sweet side; caryophyllene lays down a peppery, spicy warmth underneath; and humulene rounds it out with a woody, hoppy depth. Together they explain the citrus and fruity sweetness without any need for extra fruit flavouring, the terpenes do the work.
CBD Content and Effects
This is a CBD-first strain, bred to lead with CBD rather than THC. It carries a medium 10–12% CBD against a low 6–7% THC, so the balance sits firmly on the CBD side and the psychoactive punch stays very gentle. That makes it a good fit for growers who want the plant and the flavour of White Widow with far less of the high.
The reported effects are focused, giggly and relaxed: a light, clear-headed and sociable character that reflects the sativa-leaning genetics and the CBD-forward make-up. It is an easygoing, daytime-friendly profile rather than a heavy one. You can explore more options like it across our wider CBD seed range.
Common Problems and Pro Tips
CBD White Widow Autoflower is an easy, forgiving grow, but it is a CBD-led auto with a tropical streak, so timing and airflow matter most.
- Harvest on time for the CBD: the value here is the 10 to 12% CBD over a low THC, so follow the 8 to 10 week window and the trichomes rather than letting it over-ripen.
- Train gently, not hard: as an autoflower it will not recover from heavy topping, so use low-stress bending while young and start it in its final pot.
- Watch the humidity: it leans to a tropical climate, so keep flowering humidity down and run a fan through the canopy to keep the buds clean as they finish.
Expert tip: it is a sativa-leaning plant, so give it a little headroom and light to the lower buds. A slow cure keeps its citrus, fruity, sweet flavour with that bright White Widow zing.
Frequently Asked Questions
Is CBD White Widow Autoflower high in CBD or THC?
It is bred to lead with CBD. It carries a medium 10 to 12% CBD against a low 6 to 7% THC, so the balance sits firmly on the CBD side with only a gentle, barely noticeable psychoactive effect. That makes it a good pick if you want the calming side without a strong high.
How long is the CBD White Widow Auto life cycle?
About 8 to 10 weeks from seed to harvest. As an autoflower it flowers on age rather than on a light change, so the clock does not stop for mistakes, and it can be run all season. Plan your feed and training around that short, fixed window to get the most from it.
Do I need to change the light cycle?
No. Keep it on a long day of 18 to 20 hours of light from seedling to harvest. It starts flowering on its own at around three to four weeks, so there is no 12/12 flip to time. A steady, generous light schedule gives this CBD auto the energy to build its buds.
Is CBD White Widow Auto good for beginners?
Yes. It is an easy, forgiving autoflower listed among our beginner-friendly strains. Start it in its final pot to avoid transplant shock, keep any training gentle with low-stress bending, and watch humidity in its tropical comfort zone. Do that and it mostly looks after itself from seed to harvest.
What does CBD White Widow Auto taste like?
Expect a citrus, fruity and sweet flavour, driven by its terpineol, gamma-terpinene, caryophyllene and humulene terpenes, with a bright White Widow zing. Dry slowly in a cool, dark space and cure in jars so that fresh, zesty character comes through at its best in the finished flower.
How much does CBD White Widow Auto yield?
It is a lower producer: 0.98 to 1.15 oz/ft² (300 to 350 g/m²) indoors and 3.53 to 5.29 oz (100 to 150 g) per plant outdoors, so plan for quality and CBD over sheer bulk. Good light and an open canopy help this CBD auto make the most of its short life cycle.
