Germination: Starting Your Gelato Grow

Start your seeds using the paper towel method.

  • Place seeds between damp (not soaked) paper towels
  • Cover with two plates for warmth and darkness
  • Keep around 70–75°F
  • Once the taproot reaches ½ inch, plant root-tip down ½ inch deep

⚠️ Avoid sealing in plastic, excess humidity can lead to rot or oxygen deprivation.

Week 1: Seedling Stage

Your Gelato seedlings will appear vibrant green and upright.

  • Keep light gentle (around 24–30″ from LED)
  • Humidity: 65–70%
  • Temperature: 72–77°F
  • Water lightly, moist but not soggy
  • Ensure soft airflow to strengthen stems

By week’s end, you’ll see the first pair of serrated leaves and a sturdy base forming.

Week 2: Early Veg + First Training

The plant begins to accelerate with strong leaf and root growth.

  • Start low stress training (LST) to shape an even canopy
  • Feed lightly (¼-strength veg nutrients)
  • Drop humidity slightly to 60–65%
  • Keep temps steady around 73–78°F
  • Avoid overwatering. Gelato likes drier soil between feedings

This early shaping prepares your plant for balanced light exposure.

Week 3: Veg Expansion

Growth takes off as new nodes and side branches fill out.

  • Height: 10–14 inches
  • Humidity: 55–60%
  • Temp: 73–78°F
  • Increase feeding to ½-strength veg formula
  • Top above the 5th node to encourage multiple colas

Gelato’s structure tends to be tall and open. Topping now helps you control vertical growth.

Week 4: Pre-Flower Preparation

Your Gelato plant is lush, full, and ready to flip.

  • Trim lower leaves for better airflow
  • Maintain RH 50–55%
  • Keep temps 72–78°F
  • End the week by switching to 12/12 lighting
  • Transition to a bloom feed schedule

You may notice early pistils forming. Flowering is about to begin.

Week 5–6: Flower Initiation

Buds begin forming at each node, and the aroma becomes noticeably sweet and creamy.

  • Height: up to 20–30 inches
  • RH: 45–50%
  • Temp: 70–77°F
  • Begin full bloom nutrients (low N, high P & K)
  • Defoliate lightly to improve airflow and light penetration

By the end of this stage, trichomes will begin to sparkle across the leaves.

Week 7–8: Bud Development

Your Gelato plant is now fully flowering. Buds are dense, sticky, and aromatic.

  • Trichomes expand rapidly, covering buds and sugar leaves
  • RH: 40–45%
  • Temp: 68–75°F
  • Maintain strong airflow
  • Optional: Add a terpene enhancer for stronger scent and flavor

The aroma shifts into creamy vanilla mixed with lemon and sweet cookie dough.

Week 9: Ripening & Flush

It’s time to refine your final product.

  • Begin flushing with clean, pH-balanced water
  • Temp: 65–70°F
  • Humidity: 35–40%
  • Watch trichomes: mostly cloudy with 10–15% amber
  • Harvest when pistils darken and curl inward

This stage ensures smooth flavor and clean combustion in your final buds.

Harvest & Curing

  • Dry: 10–14 days at 60°F and 55% RH in darkness
  • Cure: Store in glass jars, burping daily for the first week
  • Let cure for 3–4 weeks for maximum flavor and smoothness

Final buds will showcase a creamy sweetness with hints of vanilla and citrus – classic Gelato perfection.

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…
