Double Mandarin is an original QCS strain: a fast, compact, indica-dominant autoflower bred from Ice Cool and Cream Caramel Auto, listed at about 16 to 20% THC and ready in roughly 8 to 10 weeks from seed. This Double Mandarin strain review covers our specs, what the listing says about its citrus-and-caramel profile, and what growers commonly report about this kind of cross.

Double Mandarin strain at a glance

What is the Double Mandarin strain?

Double Mandarin is an original QCS strain: Quebec Cannabis Seeds is its original breeder, and these are our own genetics bred in Quebec.

Double Mandarin Autoflower is built for people who want a quick, easy plant that smells like a dessert. Quebec Cannabis Seeds bred it from Ice Cool and Cream Caramel Auto, so the autoflowering trait is already in the family. It is feminized, compact and listed at about 8 to 10 weeks from seed to harvest, which makes it one of the faster plants in our range.

It is a newer listing with no customer reviews yet, so this review leans on the QCS specs and on what growers commonly say about creamy, citrus-leaning autoflowers. The name suggests a mandarin-and-cream flavour, and the product page describes bright mandarin and citrus notes over caramel sweetness. Other companies may use similar names for different crosses; the numbers here are for the QCS version only.

Is Double Mandarin indica or sativa?

QCS describes Double Mandarin as indica dominant but does not give an exact split, so we will not invent one. In the garden, indica-leaning autoflowers usually mean short, sturdy plants with dense flowers, which fits the compact build on the product page.

The page also describes the high as balanced, which is a useful reminder that indica and sativa labels are rough guides. If you want background on the indica side, read what indica does to you.

Smell and flavour: citrus, cream and vanilla, caramel

QCS lists the taste as citrus, cream and vanilla, and caramel, and the description adds bright mandarin notes with caramel sweetness. It is an easy profile to like: sharp and juicy at the front, soft and sugary behind. Consumers who like dessert-style cannabis often look for exactly this kind of cream-and-citrus mix.

Growers commonly report that sweet, citrus-forward flower keeps its character best with a slow, careful dry and a cure of a few weeks. Rushing the dry tends to flatten the delicate citrus notes first.

Double Mandarin effects

The listing describes a balanced high. Consumers describing creamy, citrus-style indica-leaning autoflowers often mention a calm, cheerful feeling without a heavy shove, though everyone reacts differently. With THC at the moderate end, it can suit people who like a gentler session or who are building tolerance.

Effects depend on dose, tolerance and setting, and dry mouth and dry eyes are commonly reported with cannabis in general. Start low and go slow, especially if you are new.

How strong is Double Mandarin? THC content

QCS lists Double Mandarin at about 16 to 20% THC. That is moderate by the standards of our catalogue and noticeably lighter than the strains in our THC over 25% seeds section. It may suit you if you want flavour and a friendly effect rather than maximum potency. The product page does not list a CBD figure.

As with every strain, the number in your jar depends on genetics, light, feeding, drying and curing, so treat the range as a guide.

Growing Double Mandarin: timing and yield

Double Mandarin flowers automatically, so you never change the light schedule. QCS gives no separate flowering time. It lists about 8 to 10 weeks from seed to harvest, with the plant staying compact. Indoors the page lists about 450 to 550 g/m², and outdoors about 80 to 100 g per plant. No outdoor harvest date is given. Because the cycle is so short, an outdoor sowing in late spring should finish well before the cold.

Growing tips

Sow straight into the final container, since autoflowers dislike transplanting. Keep light, temperature and feeding steady, and go easy on nutrients early, as small plants burn easily. Gentle low-stress training can spread the canopy without costing time. Because the cycle is short, harvest by checking trichomes rather than the calendar.
