3. Seedling Stage

Congratulations! Your Gelato 33 seeds have broken through the soil and entered the seedling stage. During this phase, which lasts roughly 2–3 weeks, it’s critical to develop a strong foundation for your future plant.

Optimal Environment:

• Light Schedule: 18 on / 6 off
• Temperature: 72–78°F
• Relative Humidity: 65–70%
• Soil pH: 6.0–6.5

Use a gentle LED or fluorescent grow light while avoiding breath from fans directly on your delicate seedlings. Make sure the soil is moist and never soaking. You can aid your seedling’s growth by feeding them a mild nutrient solution (¼ strength of your recommended dosage).

4. Vegetative Growth Stage

The vegetative stage is where Gelato really starts to establish its structure and mass. Growth is abundant during this stage as your Gelato resembles its deep green colors and epic yield capabilities.

Environment & Setup:

• Light Schedule: 18/6
• Ideal Temperatures: 70–85°F
• Relative Humidity: 55–60%
• Airflow: Moderate to strong. (Use oscillating fans to strengthen stems.)

Increase yields with these training methods:

• Low Stress Training (LST): Utilize this method by bending the branches away from the center of the plant, allowing you to open up the canopy.
• Topping: Cut just above the 4th node to produce multiple cola sites from your main stem.
• ScrOG: A screen of green is great for indoor grows who want even light distribution across all colas.

Feeding Your Gelato 33 Plant: During veg, Gelato responds well to nitrogen-rich nutrients. Try an organic formula like worm castings, bat guano, or kelp meal.

5. Flowering Stage

As mentioned earlier, Gelato has an 8–10 week flowering stage. This is when you’ll see the strains potent trichomes and vibrant purple coloring.

Setup:

• Light Schedule: Begin a 12/12 schedule (12 hours light / 12 hours dark)
• Temperature: 68–78°F
• Humidity: 40–50%
• Nutrients: Begin using a phosphorus- and potassium-rich fertilizer. Look for a bloom booster at your local grow shop. Lower your nitrogen intake during this stage to prevent leafy buds.

Color & Aroma Development: During the final 3 weeks, growers often notice Gelato 33 producing sweet and creamy aromas with hints of fruit. Lowering night time temperatures to around 65°F will enhance purple coloration.

6. Harvest Gelato 33 Marijuana

Timing is critical for any harvest, as cannabis potency and flavor degrade rapidly after the fact. For Gelato 33, as well as most other cannabis strains, trichomes will be your best indicator of harvest readiness.

Look for… * Pistils to be 70–90% brown and receded

• Trichomes to be cloudy with 10–20% amber colors
• A heavily sweet and creamy aroma

Harvesting: For most growers, harvesting by cutting the main stem at the base and hanging your plant upside down works best. Dry your harvest in a dark room with around 50% humidity and 70°F temperature. Dry for 7–10 days while avoiding direct airflow on the plant.

Note: Commercial growers typically wet trim for ease and preservation of the buds. Home growers dry trim their small yields to preserve more terpenes.

7. Cure Gelato 33

Now comes the fun part: curing! When done properly, curing your freshly harvested Gelato 33 buds can mean the difference between great and legendary flavor.

All you’ll need to do is… * Place buds in airtight glass jars. Fill jars ¾ of the way full.

• Store jars in a cool dark location (ideally between 60–65°F, 55% humidity).
• “Burp” jars once a day for the first 2 weeks to allow moisture to escape.
• Continue to let buds cure for a minimum of 3–4 weeks.

Keep in mind that Gelato 33’s sweet orange sherbet flavor profile will only intensify with a proper cure.

8. Grow Gelato 33 Indoors or Outdoors?

Grow Gelato 33 Indoors:

• Pros: Allows for a controlled climate leading to more consistent results. Gelato performs well under carbon filters to reduce smell.
• Cons: Yields average around 500–600g/m².

Grow Gelato 33 Outdoors:

• Pros: Ripens perfectly in Mediterranean type climates. Can produce up to 900g/plant if given adequate sunlight.
• Cons: Harvest time approaches mid to late October. If growing outdoors, try to find feminized Gelato 33 seeds that have high pest resistance traits.

9. Gelato 33 Growing Tips – Avoid These Mistakes

No matter how experienced you may be, we’ve all made mistakes when trying to grow cannabis. Avoid hassles and headaches with these common-growing errors.

• Overfeeding nutrients causes nutrient lockout and burned leaf tips.
• Skipping pH levels will hurt your plant. Try to maintain a pH between 6.0–6.5 for soil/grown conditions.
• Overwatering. Cannabis plants, like Gelato 33, prefer to grow in slightly dry soil. Allow soil to dry out between waterings.
• Not enough airflow can cause mold and bud rot. Place an oscillating fan inside your grow room and ensure constant air movement.
