Climate: Warm & sunny
Soil: Well-draining, nutrient-rich
Harvest: Late September to early October

Environment	Height	Yield	Flower Time	Difficulty
Indoor	50–60″	1.3–1.6 oz/ft²	9–10 weeks	Moderate
Outdoor	50–60″	15–18 oz/plant	End Sept–Early Oct	Moderate

Germination: Starting Your Sundae Driver Grow

Use the paper-towel method for consistency:

Place seeds between two damp (not wet) paper towels
Cover with plates to maintain darkness and warmth
Keep temp around 70–75°F
Once tap-root ~½″, plant root-tip-down about ½″ deep
Avoid sealed plastic bags; airflow is key to prevent rot.

Week 1: Seedling Stage

Your plant is just getting started and needs a stable environment.

Keep humidity at about 65–70%, temp 72-77 °F
Light: low intensity, 18–24 h cycle
Water gently, just around the root zone
Provide gentle airflow to strengthen stems
By week’s end you’ll see the first true leaves and a healthy green colour.

Week 2: Early Vegetative Growth

Growth picks up speed. Stems strengthen and side branches begin to form.

Start light LST (low stress training) to open the canopy
Feed at ~¼-strength veg nutrients
Humidity: ~60–65%, temp: 73-78 °F
Keep pots from getting water-logged
Good foundation now pays off later.

Week 3: Veg Expansion

The plant enters robust growth.

Height around 10–14 inches
Drop humidity to ~55-60%, keep temp 73-78 °F
Increase nutrients to ~½-strength veg feed
Consider topping or trimming to control height and encourage multiple colas
You’ll see thick foliage, strong branching and imminent transition preparations.

Week 4: Pre-Flower Transition

Your plant is just days away from flowering.

Remove lower growth blocking light to the top canopy
Reduce humidity to ~50-55%
Temperature: 72-78 °F
No heavy training; tie down what’s needed
Prepare to flip to 12/12 lighting
Early pistils will begin to show at the nodes by end of week.

Week 5–6: Flower Initiation

Switch to 12/12 lighting and watch the buds forming.

Height may rise a bit as stretch happens but stay manageable
Humidity: ~45-50%, temp: 70-77 °F
Switch to bloom nutrients (lower N, higher P & K)
Aroma shifts into fruity-grape, vanilla and sweet dessert tones
This phase sets the stage for dense resin development.

Week 7–8: Bud Development

Buds are swelling, resin is covering sugar leaves, the aroma is rich.

Humidity: ~40-45%, temp: 68-75 °F
Maintain bloom feed, ensure airflow remains strong
Optional: terpene booster later this phase
You’ll be rewarded with thick, sticky colas smelling like dessert sundae with grape and vanilla.

Week 9–10: Ripening & Flush

Final push to maturity.

Flush with clean, pH-balanced water for 5–7 days
Temp: 65-70 °F, humidity: ~35-40%
Trichomes: mostly cloudy with some amber, ideal harvest window
Pistils: 70–80% darkened/curling inward
Harvest between end of September and early October for optimal flavour and potency.

Harvest & Curing

Dry: hang branches in darkness at ~60 °F, 55% RH for ~10–14 days
Cure: place trimmed buds in glass jars, burp daily the first week then weekly
Cure 3–4 weeks to bring out full vanilla, grape and sweet dessert aromas
Curing does more than preserve. It unlocks the best flavour and smoothness.
