Week by week

Germination: Days 1–7

Pop the seed.

Soak in a moist paper towel or plant 1cm deep in light, airy soil.
Keep warm (22–25°C), humid and dark until the sprout appears.
Moist, never soggy.

Seedling: Weeks 2–3

First true leaves.

Gentle light on 18/6, high humidity (~65%).
Tiny waterings near the stem; let the top dry between.
Quarter-strength nutrients at most.

Vegetative: Weeks 4–7 (you control length)

Build the plant.

Photoperiod: keep 18/6 as long as you want size, then flip to 12/12 to begin flowering.
Feed grow (high-N) nutrients; train (LST/topping) for an even canopy.
Hybrid structure, balance height and bush with light training.

Flowering: ~8–9 weeks of bloom

Buds bulk up.

Now on 12/12. Expect a 2–3 week stretch early, give headroom.
Switch to bloom (high-P/K) nutrients; lower humidity (~45%) to prevent bud rot.
Watch trichomes: mostly cloudy with some amber = peak ripeness.

Flush & harvest: Final 1–2 weeks

Finish clean.

Plain water (no nutrients) the last 1–2 weeks for a smoother smoke.
Harvest, wet-trim, dry slowly (~60°F / 60% RH, 7–14 days).
Cure in jars 2+ weeks, burping daily at first.

~15–17 weeks (plus veg time).

Growing Glueberry O.G. outdoors

Outdoors in central Europe photoperiod plants start flowering in early to mid August, so Glueberry O.G., with 8 to 9 weeks of flowering, is usually ready in late September to mid October. That is late in the season: autumn rain and cold bring bud rot, so it suits a greenhouse, a dry southern spot or an indoor grow better than an open northern garden.

Drying and curing

Its berry and sweet notes come from the most volatile terpenes, the first to go in a warm, fast dry. Dry slowly around 18 °C and 60% humidity for 10 to 14 days and cure in jars to keep them.
