What our team says about growing Zeclair

Here's the real deal on running Zeclair in production:

She stacks weight fast in weeks 5-7, so brace your branches early or you'll be scrambling with stakes mid-flower.

Feed her heavier than you think—this girl eats. Push phosphorus in flower or she'll underperform on resin production.

The fade comes hard and gorgeous if you dial back nitrogen by week 6. Purples and deep greens bleed through beautifully.

Don't harvest early—wait for 10-15% amber trichs. That's when the sedation really locks in and terps fully mature.

Dense structure means airflow is critical. Strip lower fan leaves at flip or you're asking for powdery mildew in humid climates.

Zeclair = Cold Heat × Zonuts — a luxury dessert cross engineered for growers who demand both fire and yield. Umami Seed Co's selection work locked in maximum bag appeal and cannabinoid density, giving this cut a creamy, sedating profile that hits like premium hash without the equipment.

Zeclair Strain Terpene Profile

• Caryophyllene — Spicy, peppery bite with anti-inflammatory depth.
• Limonene — Sweet citrus cream that brightens the palate.
• Linalool — Floral lavender notes; calming and sedative.
• Humulene — Earthy herbal backbone with subtle wood tones.

Overall aroma: vanilla éclair frosting, sweet dough, candied citrus zest, and a whisper of floral perfume. The cure amplifies that bakery sweetness—jars smell like walking past a French patisserie at dawn.

Zeclair Grow Tips

• Stretch: 1.5×–1.8× (moderate; manageable indoors).
• Flower Time: 56–63 days indoors (8–9 weeks).
• Yield: 2.1–2.6 lbs/light with proper LST and defoliation.
• Bud Structure: Golf ball-dense nugs; tight node spacing.
• Feeding: Heavy phosphorus feeder; loves bloom boosters from week 3 onward.

Pro tip: Zeclair thrives under high-intensity light but watch for light stress—those dense tops can bleach if you push PAR too hard in late flower. Trellis nets help distribute weight evenly and prevent branch snap.

Zeclair Appearance: Bag Appeal & Bud Traits

Picture compact, rock-solid colas dripping in frosty trichomes with deep purple undertones and fiery orange pistils twisted through every bud. The resin coverage is absurd—looks like someone rolled each nug in powdered sugar. Colors shift from forest green to plum during the fade, and the density makes every jar feel heavier than it looks. This is dispensary top-shelf material that moves itself.

Zeclair Rosin Behavior

• Wash yield (fresh frozen): 4.2–5.1%.
• Rosin return: 22–25% (dry cured flower).
• Press temp: 170–180°F.
• Best texture: Creamy badder with dessert-forward terps.

Hash heads are obsessed with Zeclair for good reason—stellar yield and flavor retention that tastes like dabbing whipped butter and vanilla bean. The rosin stays stable at room temp and never sugars up too fast, making it perfect for small-batch concentrates.
