Zkittlez R1 Feminized at a glance
Zkittlez R1 Feminized is a photoperiod plant from the Zkittlez line, listed at 22 to 24% THC. The aroma runs from grape and grapefruit to berry and candy, led by limonene, and the effect pairs a relaxed body with a lifted mood and a clear head. It flowers in 8 to 9 weeks (56 to 63 days).
Genetics
The listing gives a single word for the genetics: Zkittlez. R1 comes from that line and keeps its grape and candy character, with a frame of its own: stocky, controlled, branching sideways, with dense, colourful buds and a generous coat of resin from the first weeks of flower.
To see what the line contributes, read our Zkittlez Feminized page, which gives the original cross and its own numbers. Put side by side, the two pages show where R1 follows the family and where it goes its own way.
Aroma and effect
Grape and grapefruit open, and berry and candy follow. Limonene gives the grapefruit-pith edge, myrcene an earthy, slightly musky base, caryophyllene the warm spice that stops the sweetness going flat, and linalool a soft floral finish.
The effect builds gradually: the body relaxes, the mood lifts and the head stays clear, never fully heavy.
Growing guide
Difficulty is intermediate: the plant forgives small feeding slips, but its dense buds ask for attention to humidity. It stands 90 to 130 cm indoors, suits Mediterranean and temperate climates, and flowers in 8 to 9 weeks (56 to 63 days) after the switch to 12 hours of light.
Indoors: from veg to flower
After one to two weeks of germination and seedling, give it only 2 to 3 weeks of vegetative growth before the flip to 12/12. Flowering then takes 8 to 9 weeks (56 to 63 days), a one-week window counted from the flip.
Keep 20 to 26°C and about 50 to 70% humidity in veg, then 40 to 50% in flower, with air moving above and under the canopy, because mould starts inside dense buds; our guide to VPD helps you balance the two.
In the last two weeks, let the nights fall 8 to 10°C below the day and the purple tones come up.
Outdoors in Quebec
Plant out once the last frost is behind you, so the plant has a long vegetative season. With an early to mid-October harvest, the cold, damp autumn on the St. Lawrence is the main risk, and cold nights can arrive early.
Our guide to predicting frost from cold nights helps you watch for them, and the outdoor growing guide for Canada covers timing by region.
Growing tips
Low-stress training or a screen of green opens the lower bud sites to light and spreads the yield over several tops instead of one dominant cola. Before you cut, check the trichomes under a loupe: mostly cloudy for a livelier result, a little amber for a deeper one.
Dry in a dark, ventilated room with the branches hanging upside down, following the golden rule of drying, 18/60/18: 18°C, 60% humidity, 18 days, with the dehumidifier running non-stop for the first 48 to 72 hours. Then cure in jars; our guide to curing and storing buds shows how to keep the fruit notes bright.
How much does Zkittlez R1 Feminized yield?
Indoors, Zkittlez R1 Feminized is listed at 450 to 550 g/m² under good light, on plants of 90 to 130 cm that fit a tent. Outdoors, a well-established plant gives 500 to 700 g. Low-stress training and a screen of green spread the light across the canopy and help you reach the top of those ranges.
Harvest falls in early to mid-October. A pack holds 6 feminized seeds, with germination at 80 to 85%, which means about five seedlings to compare, and

FAQ
What does Zkittlez R1 smell like?
Grape and grapefruit lead, with berry and a candy sweetness behind them, so the room smells fruity well before harvest. Limonene gives the sharp citrus edge. The smell builds through late flower, so plan a carbon filter in the tent, or a spot downwind of the house if you grow outdoors.
What is the THC level of Zkittlez R1?
Zkittlez R1 Feminized is listed at 22 to 24% THC, a high figure for a fruit-forward variety. Where a plant lands depends on light, feeding, humidity in late flower and the day you cut. A slow dry and a few weeks in sealed jars protect the resin and the fruit notes.
What terpenes are in Zkittlez R1?
Four terpenes define it: limonene first, then myrcene, caryophyllene and linalool. Limonene brings the grapefruit brightness, myrcene an earthy, musky base, caryophyllene a warm spice and linalool a soft floral finish. They are fragile, so dry slowly at 18°C and cure the buds in jars.
How tall does Zkittlez R1 grow?
Indoors, Zkittlez R1 Feminized stands at 90 to 130 cm, a size that suits a tent with limited height. It is stocky and branches sideways, so low-stress training keeps the canopy even. Outdoors, give it room: a well-established plant gives 500 to 700 g.
Is Zkittlez R1 a good strain?
Yes, if you want a fruit-forward plant that fits a low tent. It stays at 90 to 130 cm indoors, gives 450 to 550 g/m² and offers a grape and grapefruit nose at 22 to 24% THC. The honest limit is the finish: early to mid-October is late outdoors along the St. Lawrence.
What does Zkittlez R1 taste like?
Fruit first: grape and grapefruit on the inhale, then berry and a smooth, candied sweetness on the exhale. Limonene keeps the citrus sharp, and caryophyllene adds a pinch of spice so the candy never goes flat. A slow cure in sealed glass jars keeps those notes bright for longer.
Is Zkittlez R1 indica or sativa?
Zkittlez R1 Feminized is listed simply as a hybrid, with no stated indica or sativa ratio, so it does not lean clearly to one side. The effect reflects that: a relaxed body with a clear head rather than a heavy one. As a photoperiod plant, it flowers only when you cut the light.
