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.

Gary Payton

Michael ClintMarch 27, 2024

I’ve been growing weed for 30+ years, and to be honest, it’s quite difficult to surprise me. After a few decades of facing different strains, changing growing conditions, and solving whatever problem you could possibly think of, by then, I believe I’ve seen it all in cannabis growing.

Gary Payton defied every single one of my expectations.
The plant thrived, growing to an impressive 6 feet in what seemed like a blink of an eye. It quickly filled out with buds and displayed better smell each day, showing solid proof of superior genetics. The buds were tight, aromatic, and a source of immense pride, surpassing the outcome of many of my previous endeavors.

Hypno Seeds with their Gary Payton strain has won my complete admiration and loyalty. Outstanding genetics in this plant have truly turned what I always thought of to be an experiment with negligible expectations into one of the most satisfying grows of my long career.

Looking forward, my excitement for the next growing season is unparalleled. I can’t wait to see how much I can take these strains, especially with the attention that Gary Payton really does deserve right from the start.

Blackberry Kush

WhildGreeneryMarch 28, 2024

Starting my latest grow, I decided to try out some Blackberry Kush from Hypno… I planted her on a whim alongside my other favorites. Hypno Seeds said it had to be a powerful plant with rich, fruity scents… Seeing is believing. She developed purplish hues and dense resin coated buds and quickly took center stage in my garden and produced much more than expected. The buds are tightly packed, literally bursting with the heady aroma. The yield? Very impressive for her conditions…
