Peanut Butter Breath strain: the short version

Peanut Butter Breath comes out of the Do-Si-Dos and Mendo Breath family, and it is one of the few strains that smells like its name. Savoury and nutty instead of sweet.

The problem with the original, for most of Canada, is the calendar. It runs late outdoors.

What Atlas changed

Atlas Seed took their favourite Peanut Butter Breath cut and crossed it with Cotton Candy, the autoflower they call their workhorse. They are clear about why. Cotton Candy brings fast flowering and mold resistance. The Mendo Breath side of Peanut Butter Breath already leans toward an earlier finish.

The result is what Atlas calls semi-full term. It is still a photoperiod plant, but a quick one. Their number: sown in mid May, it finishes in mid September.

What it smells like

Atlas describes the nose as nutty, with a forest floor aroma and a rich herbal overtone. They say the smoke is similar. Cotton Candy adds what Atlas calls sugary fuel to the flowers.

Effects

Atlas does not publish a THC figure for this cross, so this is about how it smokes. It comes from the Do-Si-Dos family, and the usual description is a calm, heavy body feel that builds over the first half hour while the head stays fairly clear. The savoury, nutty flavour lingers. Most growers keep it for evenings, with a small bowl on a slow afternoon.

Flowering, harvest and cure

Atlas calls this semi-full term, so it finishes ahead of a classic Peanut Butter Breath but behind an autoflower. The label gives about 9 weeks of flowering. In late flower the buds stack into tight, frosty clusters and the nutty smell comes up whenever you brush the plant. Cut by trichomes under a loupe: mostly cloudy heads with a few amber, and pistils that have curled in and darkened. Dry slowly in a cool room with steady airflow, then jar and open the jars daily for the first week.

Growing Peanut Butter Breath in Canada

Start seeds indoors in late April or early May and plant out after the last frost, usually late May in southern Canada. Flowering begins as the days shorten in August, and the breeder's own figure is mid September from a mid May sowing. On the Prairies an early frost can cut that close, so a tunnel or a tent run is safer. In Ontario, Quebec and the Maritimes, September humidity is the thing to plan for: space the plants wide and strip lower growth so tight buds can dry after dew.

Peanut Butter Breath outdoor calendar for Canadian cities

Peanut Butter Breath is a photoperiod plant, so outdoors it starts flowering in early August, when the nights get longer. Add its 9 to 9 weeks of flowering and you get the harvest window below.

Halifax, NSMay 19Oct 3 to Oct 10Good

Dates use typical frost dates for each city and shift a week or two with the year, so check your local forecast before planting out and in late September.

Who Peanut Butter Breath suits

Anyone with a short outdoor season who still wants a photoperiod plant, and tent growers who like to pick the flip date. A good fit for a sunny backyard in the south, less so for a very low closet. Give it a bigger pot than you think you need, since a plant started in May has the whole summer to fill it, and keep a notebook of your own flip and harvest dates for next year.

Will it finish where you live?

This is where the Atlas version earns its place.

Yes

Southern Ontario and south coast BC

A mid September finish is ahead of the first frost and ahead of the worst of the fall rain.

Ontario guideBC guide
Tight

The Prairies

Tight. First frost can land in mid September. Start it indoors in April so it goes out with a head start, or grow it in a tent.

Workable

Atlantic Canada

Workable in a sheltered spot. September is damp, so the mold resistance from Cotton Candy matters here.

Yes, year-round

Indoors, any province

Switch the lights to 12 and 12 when the plant is half the height you want.

How to grow it

Sow in May, not June

The mid September finish is counted from a mid May sowing. Start late and you finish late.

Give it room and air

Space the plants so air moves through them. The breeder chose the Cotton Candy cross partly for mold resistance, but no plant is immune in a wet September.

Do not rush the last two weeks

The nutty aroma builds late. Cut on the trichomes, not on the date.

Dry it slowly

Dry cool and slow to hold on to the savoury notes. A fast, warm dry flattens them.

Peanut Butter Breath questions

When does Peanut Butter Breath finish outdoors?

Atlas Seed says mid September if it is sown in mid May.

Does it really smell like peanut butter?

It is nutty and savoury. Atlas describes a nutty, forest floor aroma with a rich herbal overtone.

Is this the original Peanut Butter Breath?

No. It is Atlas Seed's version: their selected Peanut Butter Breath cut crossed with Cotton Candy to finish faster.

Is it an autoflower?

No. It is a fast photoperiod, which Atlas calls semi-full term. Indoors you still switch the lights to 12 and 12.

Can I grow it outdoors in Canada?

Yes in the longer-season regions, where your province allows it. On the Prairies, start it indoors or grow it in a tent.

Is Peanut Butter Breath indica or sativa?

Atlas does not publish a split for this cross. It comes from the Do-Si-Dos and Mendo Breath family, which leans indica, and the plant grows like a bushy, quick hybrid.

What does Peanut Butter Breath taste like?

Nutty and savoury, with a forest floor depth and an herbal finish. A slow cure keeps those notes and a hot, fast dry flattens them.

How is this different from the original Peanut Butter Breath?

The original runs late outdoors. This version crosses Atlas's own cut with Cotton Candy to finish earlier and handle damp weather better.

5 out of 5

I ordered a 5 pack and received 8! if that was not awesome enough all 8 beans germination in record time. they obviously came from a very fresh batch. This company is a great one to go through. I have gone through the seed pharm for years now and never been disappointed. I will be using them again.
