How to Grow 1 CA CBD

1 CA CBD, sold as CBD 1-CA (1:20), is a high-CBD strain for growers who want flower rich in CBD and very low in THC. A 60% sativa feminized plant with ACDC and Sour Diesel in its background, it carries 18-20% CBD with only about 0.8% THC, a roughly twenty-to-one ratio, so it is barely intoxicating by design. At a compact 3.94 ft and 8-10 weeks of flowering, the 1 CA CBD strain grows like an easy photoperiod while producing clean, earthy, lemon-pine, CBD-rich buds.

This guide covers the full cycle for CBD 1-CA (1:20) feminized seeds from Blimburn Seeds, from germination to the cure, with every figure taken from the official datasheet. Nothing here is medical advice; cannabis is not a medicine.

The defining numbers are the cannabinoids: high CBD at 18-20% with very low THC around 0.8%, the roughly 1:20 ratio the strain is named and sold for. The 1 CA CBD strain is grown for clean, CBD-rich flower rather than a strong high, and everything else, the compact size, the medium yield, the standard 8-10 week bloom, makes it easy to grow.

The ACDC and Sour Diesel Parents of 1 CA CBD

ACDC is the source of the CBD. One of the most famous high-CBD, low-THC cultivars in cannabis, it is the reason 1 CA CBD reaches 18-20% CBD while staying around 0.8% THC, and it contributes the clear, gentle character of the effect.

Sour Diesel adds the energy and the flavor. A legendary sativa, it lends the lively, sociable lift, the lemon-and-diesel sharpness in the aroma, and the stretchy, vigorous growth of the 60% sativa structure. A secret hybrid parent rounds out the cross and stabilizes the line.

That places 1 CA CBD firmly among Blimburn’s CBD seeds and its all-female feminized CBD seeds, bred specifically for a high-CBD, low-THC harvest with real flavor.

Germination and the Vegetative Phase

Germinate with the paper-towel method at 70-79°F. Set the seeds between damp paper towels on a covered plate, keep them dark, and wait for taproots within 24 to 120 hours. Plant each half an inch deep in light, well-draining soil, taproot down.

Every 1 CA CBD seed is feminized, so each plant flowers female. Veg under 18 hours of daily light for four to six weeks in 3-5 gallon containers. Growth is sativa-leaning but stays compact at around 3.94 ft, and the plant trains easily, which, with its simple habit, fits the beginner-suitable rating on the datasheet.

Top above the fourth node and apply low-stress training to open the canopy and even out the sativa growth. The modest height makes 1 CA CBD easy to keep tidy in a tent or a small outdoor space.

Growing 1 CA CBD Indoors

Indoors, 1 CA CBD is straightforward. Flip to 12/12 once plants reach about half their target height; the post-flip stretch is moderate for a 60% sativa, and flowering completes in 8-10 weeks. The compact 3.94 ft frame fits any tent comfortably.

Hold lights-on temperatures at 70-82°F to suit the tropical heritage, humidity at 50-60% in veg and 40-45% in bloom. Good airflow and light keep the buds clean and the CBD-rich resin developing. Indoor yield lands at a steady 1.31 oz/ft² (400 g/m²) of earthy, lemon-pine flower.

Growing 1 CA CBD Outdoors

Outdoors, 1 CA CBD wants a tropical-to-warm climate with a dry run into its October harvest. In the United States that suits Southern California, the Arizona low desert, Florida, and the warm Gulf Coast, regions with strong, steady late-season sun. Each plant returns 14.11 oz (400 g) of dried flower from a discreet 1.2 m frame.

Plant in full sun after the last frost in 15+ gallon containers or amended ground. The compact size makes 1 CA CBD easy to screen and manage, and good spacing and airflow keep the sativa-structured buds clean as they fill. For growers specifically after a high-CBD, low-THC outdoor crop, it is a simple, reliable pick.

Flowering and Buds of 1 CA CBD

Flowering is steady and even across the 8-10 week bloom. 1 CA CBD forms medium, sativa-structured buds that fill in gradually with a clean coat of resin, and the earthy, lemon-pine aroma builds through flowering, sharpened by the Sour Diesel side.

Because this is a CBD strain, the resin is rich in CBD rather than THC, but the buds still frost up well. Keep airflow steady and the canopy open; clean, well-ripened flower is what preserves the cannabinoid content and the bright lemon-pine flavor.

Common Problems and Pro Tips

1 CA CBD grows like an easy photoperiod, so there are no unusual difficulties. The main thing to understand is simply what it is: a high-CBD strain with very low THC, so it will not produce a strong high no matter how it is grown. That is by design, not a growing fault.

The sativa lean means a little stretch, so train early if your space is tight. Expert tip: harvest timing here is about flavor and a clean finish rather than chasing potency. Watch the trichomes and pistils for ripeness as you would any strain, keep bloom humidity around 40-45%, and cure carefully to bring out the lemon-pine character.

Feeding and Watering

1 CA CBD feeds moderately, with a light hand early and steady phosphorus and potassium later in bloom.

StageECpHNotes
Seedling0.4-0.66.0-6.5Plain water or quarter-strength feed
Vegetative0.8-1.26.0-6.5Nitrogen-forward, add silica for stems
Preflower1.2-1.46.0-6.5Transition formula at the 12/12 flip
Bloom1.3-1.56.0-6.5Phosphorus and potassium, kept moderate
Flush0.0-0.46.0-6.5Final 10-14 days, plain water

Water when the top inch of the medium dries, letting the pot lighten between rounds. The plant feeds moderately, so build nutrient strength up gradually and avoid pushing hard, which only risks burn on a compact, even-growing plant like this.

Finish with 10-14 days of plain water at EC 0.0-0.4. The earthy, lemon, pine profile is clean and bright, and a proper flush keeps it crisp on the exhale.

Flavor, Terpenes, and Effects of 1 CA CBD

The flavor is clean and fresh: an earthy base lit by bright lemon and a crisp pine edge. Two terpenes lead the profile. Pinene drives the fresh, resinous pine and supports the citrus lift that gives the strain its lemon note, while bisabolol rounds the base with a soft, gentle, faintly chamomile smoothness that keeps the whole thing easy and uncluttered.

The effect is defined by the cannabinoid ratio. With 18-20% CBD and only about 0.8% THC, 1 CA CBD is barely intoxicating; the datasheet describes it as happy, relaxed, and talkative, a clear-headed, sociable experience rather than a strong high. It is chosen by growers who specifically want high-CBD, low-THC flower. This is a description of the strain, not medical advice, and cannabis is not a medicine.

Harvesting, Drying, and Curing

Check trichomes and pistils from week seven. Harvest when most trichomes are cloudy and the pistils have largely darkened and curled; with a CBD strain, timing is mainly about flavor and a clean finish rather than chasing a THC peak. Take the riper upper buds first.

Dry whole branches at 59-68°F and 50-55% humidity for 7-14 days in darkness with gentle airflow, waiting for stems that snap. Cure in glass for at least three weeks, burping daily early on; the earthy, lemon-pine profile sharpens and cleans up noticeably with a patient cure.

What to Do With Your Trim

The CBD-rich sugar leaves are worth keeping. Dry-sift them for a fresh, lemon-pine kief, run ice-water bags for hash, or save the trim for homemade extracts and infusions, where the high-CBD, low-THC profile makes for an easy, mild result. Little needs to reach the compost.

Is 1 CA CBD indica or sativa?

1 CA CBD is sativa-leaning, at 60% sativa to 40% indica, reflecting its Sour Diesel side. It grows with a moderately stretchy structure but stays compact at 3.94 ft, and the datasheet describes its effect as clear-headed and sociable, in keeping with the sativa lean.

How long does 1 CA CBD take to flower?

1 CA CBD flowers in 8-10 weeks after the switch to 12/12 indoors, a standard window. Grown outdoors in a tropical-to-warm climate, the 1 CA CBD strain is ready to harvest in October. Check trichomes and pistils from week seven to time the cut.

What does the 1 CA CBD strain taste like?

1 CA CBD tastes earthy with a bright lemon lift and a crisp pine edge, shaped by the Sour Diesel side. Pinene drives the fresh pine and citrus, while bisabolol adds a soft, smooth base. The clean profile sharpens with a full cure.

Is 1 CA CBD good for beginners?

Yes. The datasheet marks 1 CA CBD seeds beginner-suitable, helped by a compact 3.94 ft frame, a standard 8-10 week finish, and an easy, forgiving habit. It grows like any simple feminized photoperiod, just with a high-CBD, low-THC result instead of a potent one.
