Tha Gelee Feminized Seeds – Sweet Grape & Candy Gas Flavor, High Yield Sativa Hybrid

Tha Gelee by The Grateful Seeds is a sativa-dominant feminized cannabis strain engineered for explosive yields, dreamy resin-coated buds, and a sweet, complex flavor that lingers like your favorite dessert.

Struggling with bland, low-yielding plants that lack personality? You’re not alone—so many strains promise the world but deliver forgettable smoke and frustrating harvests.

This isn’t just another Runtz cross—it’s a refined expression of its lineage, built for reliability and sensory impact. Whether you’re growing in a closet or your backyard, Tha Gelee adapts with grace, rewarding you with dense, frosty colas that practically glow under your lights.

How to grow Tha Gelee like a pro (even if you’re not)

Tha Gelee thrives with basic care and responds beautifully to simple training. Here’s how to unlock its full potential:

1. Start seeds in a warm, humid environment (22–25°C / 71.6–77°F) using the paper towel method or directly in a light soil mix.
2. For indoor grows, transplant into 7–11 L (1.85–2.91 gal) pots and fit up to 16 plants/m² (16 plants/10.76 ft²) for SOG setups.
3. Use an 18/6 light cycle during veg and switch to 12/12 to initiate flowering; maintain temps 20–26°C (68–78.8°F) and RH 40–60%.
4. Outdoors, plant in 50 L (13.21 gal) containers or directly in the ground after the last frost; harvest in late September to early October (Northern Hemisphere).
5. Flush for 7–10 days before harvest when trichomes turn milky with some amber for a smooth, flavorful smoke.

Frequently Asked Questions

Is Tha Gelee suitable for beginner growers?

Absolutely! Its resilience, straightforward feeding needs, and forgiving nature make it a great choice for first-timers—plus, the high yield is a huge confidence booster.

How strong is the smell during flowering?

Tha Gelee is loud—expect a powerful sweet-grape aroma that fills your grow space. A quality carbon filter is highly recommended for discretion.

Can I grow Tha Gelee outdoors in a cooler climate?

It prefers warm, sunny conditions, but with early planting and protection from late-season rain, it can perform well in temperate zones. Just ensure it gets plenty of light.

What’s the best way to maximize resin production?

Maintain stable temps, avoid overfeeding during late flowering, and consider using a bloom booster like Bloombastic to enhance trichome density and flavor.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of Runtz-adjacent strains, but Tha Gelee stands out for its consistency and vigor. I ran a small SOG tent with 9 plants in 11L pots, and every single one delivered dense, glistening colas with that signature candy-grape punch. The smell during late flower was intoxicating—like walking into a gourmet candy shop.

What really sold me was how easy it was. No pH drama, no nutrient burns, just steady growth and a massive harvest after 65 days. I cured the buds for three weeks, and the smoke is smooth, flavorful, and perfectly balanced—not too racy, not too sedating. It’s now a staple in my personal seed rotation, and I keep recommending it to friends who want quality without the headache.
