What is the Biscotti strain?

Biscotti is an indica-heavy dessert strain bred in California from the Gelato 25 cut and South Florida OG. It quickly became a go-to parent for modern breeding, and its sweet, toasty profile now turns up in newer hybrids such as Permanent Marker.

The two parents split the work. Gelato 25 delivers creamy sweetness, purple flecks and heavy resin from its Sunset Sherbet and Girl Scout Cookies background. South Florida OG adds old-school fuel, extra potency and a sturdy, easy-to-manage frame. Together they produce a short, bushy plant with tight internodes and dense, grape-sized buds in deep green and violet.

The name fits the flavor: picture an almond cookie dunked in coffee, with a gassy note on the exhale. These feminized seeds are bred to produce female plants, and Biscotti phenotypes are known for staying tight and uniform from plant to plant. It also shares Gelato ancestry with Lemon Cherry Gelato, which takes the same family in a fruitier direction.

Biscotti

How it feels

Consumers commonly describe a fizzy, giggly start that makes conversation and music more fun, followed by a slow slide into warm body relaxation. The full arc tends to run two to three hours.

First 10-15 minutesFizzy, giggly mood
Small things turn funny and conversation comes easily, according to many reports.
Within the hourWarm body comfort
The OG side arrives gradually as a heavy, relaxed feeling from the neck down.
2 to 3 hoursSerene and sleepy
Larger amounts often end in drowsiness, which makes it a common after-dinner choice.

Commonly reportedGigglyRelaxedEuphoricSleepy

Reported THC of 20-25% is still strong for occasional consumers, so begin with a small amount. Dry mouth and red, dry eyes are the most frequent complaints, and some people report anxiety or dizziness when they overdo it. This is a summary of general reports, not medical guidance.

Aroma, flavor and terpenes

Sweet cookie dough and toasted nuts up front, a roasted coffee middle and a fuel-like OG finish. The smell builds steadily through bloom, so plan on carbon filtration indoors.

HumuleneWood, earth, hops

Adds the dry, toasted-nut edge.

Slightly cooler nights in the last two weeks can draw out violet color. After the chop, dry at about 60°F and 60% RH so the coffee and nut notes survive into the cure.

How to grow Biscotti

Rated moderate. It stays short and bushy, which makes it easy to fit indoors; the challenge is keeping air moving through its tightly packed bud sites.

Indoors

Veg climate: 74-80°F, 55-65% RH
Flower climate: 68-79°F, 40-45% RH
Late flower: Cooler nights for violet color
Light: 700-900 PPFD in flower (LED)
Training: Top twice, LST to open the bush
Feeding: Light to moderate; avoid excess nitrogen

Outdoors

Plant out: After frost, nights steady above 50°F
Size: 5-6 ft, compact and bushy
Harvest: Early October
Best fit: Sunny, sheltered sites (USDA 6-10)
Watch for: Moisture trapped in tight buds
Protect: Thin inner leaves; shelter from wind and rain

Read the full indoor grow guide

Biscotti is one of the easier dessert strains to fit into a small space. Short internodes and an indica-heavy frame keep it at about 3 to 4 feet indoors, so it suits a 2×4, 3×3 or 4×4 ft tent. The moderate rating is mostly about airflow: the bush is dense, and the buds stack close together.

Environment

Vegetative: 74-80°F at 55-65% relative humidity.
Flower: 68-79°F with RH held near 40-45%. Steady, gentle airflow through the canopy matters more than strong wind across the tops.
Color: letting night temperatures drop a little in the final two weeks can pull out violet tones without stressing the plant.

Light and training

Run about 500-700 PPFD in veg and 700-900 PPFD in flower. Because the plant grows wide rather than tall, topping twice and pulling branches outward with LST creates more even tops. Strip small, shaded growth from the lower third before the flip; lollipopping keeps energy in the buds that matter.

Feeding

Keep the feed light to moderate. Indica-heavy plants from the Gelato line tend to show dark, clawing leaves when nitrogen runs too high in flower. A cal-mag supplement under LED prevents most mid-bloom spotting.

Harvest timing

Most phenotypes finish 8 to 9 weeks after the switch to 12/12. Use a jeweler’s loupe on the trichomes: mostly cloudy for a lighter, more giggly result, or a share of amber heads for the sleepier finish many Biscotti fans prefer.

Seed to jar in about 22 weeks

A typical indoor timeline. Biscotti stays compact, so a slightly longer veg helps it fill the space.

Growing Biscotti outdoors in the US

Outdoors, Biscotti stays manageable at about 5 to 6 feet and can produce roughly 18 to 21 ounces per plant in full sun. Its early October finish is a real advantage: it usually comes down before the cold, wet weeks that hit many northern gardens later in the month. Plant out after your last frost date, when nights hold above about 50°F.

Choose a sunny spot with some shelter from wind and driving rain. The buds are tight, so remove some interior leaves in late summer and give the plant room to breathe. Cool autumn nights can turn the buds purple, which many growers count as a bonus. For planting windows by zone, read when to plant marijuana outdoors.

Laws on growing at home vary widely, from generous plant limits in some states to outright bans in others. Look up your state on our marijuana laws by state page before you start.

Will it finish where you live?

ExcellentInland California and the Southwest

Dry, sunny falls and cooling nights finish the buds clean with good color.

GoodColorado Front Range and Utah valleys

An early October harvest usually beats the first hard frost at lower elevations.

GoodMidwest

Its early finish lands before most of the cold, rainy October weather.

FairNortheast

Workable with airflow and leaf thinning; humid Septembers are the main risk.

FairSoutheast and Gulf Coast

Long seasons help, but high humidity calls for wide spacing and a rain cover.

Biscotti FAQ

Is Biscotti indica or sativa?

Biscotti is an indica-dominant hybrid, usually described as around 80% indica. It grows short and bushy, and its effects lean relaxing after a giggly, social start.

How strong is Biscotti?

Our supplier reports THC in the 20-25% range, which is strong for most consumers without sitting at the very top of the scale. Phenotype, environment and harvest timing all affect the final number, so treat it as a typical range.

How long does Biscotti take to flower?

Indoors, most plants finish 8 to 9 weeks after the switch to 12/12. Outdoors in the US, expect harvest in early October.

How much does Biscotti yield?

A well-trained indoor canopy can return about 1.3 to 1.6 ounces per square foot. Outdoor plants in full sun can reach roughly 18 to 21 ounces each, with training and season length driving the result.

Is Biscotti good for beginners?

It is rated moderate. The compact size makes it easy to manage in a tent, but newer growers need to keep humidity near 40-45% in flower because the buds are very dense.

What does Biscotti smell and taste like?

Sweet cookie dough, toasted nuts and coffee, finished with OG-style gas. Caryophyllene, limonene and humulene are commonly reported in its terpene profile.

Where does Biscotti grow best outdoors in the US?

Inland California and the Southwest are ideal, and its early October finish also makes it a solid choice for the Midwest and the lower valleys of Colorado and Utah. Humid Northeast and Gulf Coast gardens can work with extra airflow and a rain cover.

Is Biscotti a parent of Permanent Marker?

Yes. Permanent Marker comes from a Biscotti x Jealousy cross that was then bred to a Sherb backcross. That is why the two share dense, cookie-style buds and a sweet base, even though Permanent Marker smells far sharper.
