Gelato 33

Gelato 33 Feminised Cannabis Seeds by Advanced Seeds

Gelato 33 is a feminised hybrid cannabis seed that crosses Sunset Sherbet with GSC Thin Mints to deliver 25% THC, 550–600g/m² indoors, and a flavour profile that genuinely stops you mid-roll to appreciate the aroma. Advanced Seeds built this one around the genetics that made the Gelato line famous in California dispensaries, then stabilised it for European growers who want reliable results without babysitting a temperamental phenotype. She finishes flowering in 55–60 days — not the fastest in the catalogue, but every one of those days is building resin-caked buds with purple hues and bright orange pistils.

Why Gelato 33 Is Worth Your Grow Space

We get asked about Gelato strains constantly — the name alone generates excitement, and for good reason. But not every Gelato cross delivers on the hype. Advanced Seeds' Gelato 33 actually does, and here's why it stands out from the dozen-odd Gelato variants floating around seed banks.

First, the yield. At 550–600g/m² indoors, you're looking at a genuinely heavy harvest for a strain pushing 25% THC. Most ultra-potent genetics sacrifice weight for resin production. Gelato 33 doesn't force that trade-off. She stacks dense, swollen buds during the final weeks of flowering, and those buds are coated in trichomes that catch the light like frost on a window. The purple hues that develop in the canopy aren't just cosmetic either — they're a sign the anthocyanins are expressing properly, which typically means you've got healthy, well-fed plants approaching peak maturity.

Second, the grow itself. With an indoor height of 90–120 cm, Gelato 33 stays manageable in a standard tent. She won't stretch into your lights or crowd out neighbouring plants. Outdoors she'll push to 200–250 cm — substantial, but not unruly. The 55–60 day flowering window is about average for a balanced hybrid, and she doesn't demand any special feeding schedule or exotic training technique. LST works well if you want to open up the canopy, but she'll produce without it.

The honest limitation? She's not an autoflower. You need to manage your light cycle, and if you're growing outdoors in northern Europe, you're dependent on the season cooperating through to late September. Growers in southern climates will have an easier time hitting that outdoor harvest window. If you want something more forgiving on timing, look at an autoflowering Gelato variant — but you'll sacrifice some of that 25% THC ceiling and the sheer weight of the indoor yield.

Flavour and Aroma Profile of Gelato 33

This is where Gelato 33 earns its dessert-counter reputation. The terpene profile leans heavily citrus on the nose — sharp, sweet, almost like candied lemon peel. Underneath that top note, there's an earthy base that grounds the scent and keeps it from veering into air-freshener territory. When you crack a cured bud open, the citrus intensifies and you catch a creaminess that the Sunset Sherbet parent passes down.

Smoking or vaping, the flavour translates faithfully from the aroma. The first inhale is sweet and smooth — no harshness, no cough-inducing sharpness. The exhale carries that earthy undertone and a faint cookie-dough warmth from the GSC Thin Mints lineage. We've seen growers describe it as "dessert in a rolling paper," and that's not far off. If you've grown strains that smell incredible in the jar but taste flat in the joint, Gelato 33 is a corrective experience. The flavour holds all the way to the roach.

During the final weeks of bloom, your grow room will smell like a patisserie that's also somehow a citrus grove. Carbon filtration isn't optional — your neighbours will have opinions otherwise.

How to Grow Gelato 33 Feminised Seeds

1. Germinate your seeds using the paper towel method or directly in a starter plug. Keep the environment at 22–25°C and maintain moisture without waterlogging. Taproots typically emerge within 24–72 hours.
2. Transplant seedlings into their vegetative container once the taproot is 1–2 cm long. Use a well-draining medium — coco/perlite mixes or light soil both work. Gelato 33 isn't fussy about substrate.
3. Vegetate under 18/6 light for 3–5 weeks depending on your target plant size. She stays compact at 90–120 cm indoors, so a shorter veg period works if your tent is on the smaller side.
4. Flip to 12/12 to trigger flowering. The 55–60 day countdown starts here. Increase phosphorus and potassium in your feed schedule as buds begin to form.
5. Watch for the purple colouring and swollen calyxes in the final 2 weeks. Trichomes should shift from clear to milky — check with a jeweller's loupe or USB microscope. Harvest when roughly 70–80% of trichomes are milky with a few turning amber.
6. Dry in a dark, ventilated space at 18–21°C and 55–60% humidity for 7–10 days. Cure in glass jars for a minimum of 2 weeks, burping daily for the first week. The citrus and cream terpenes develop significantly during a proper cure.

Gelato 33 Compared to Other Gelato Strains

The Gelato family tree is sprawling, and picking between phenotypes can feel like choosing between desserts at a bakery — they're all good, but they're not the same. Here's how Gelato 33 stacks up against two common alternatives you'll find in the catalogue.

Gelato 33 wins on yield and THC ceiling. The auto version is easier for first-timers who don't want to manage light cycles, but you're giving up 100–200g/m² and a few percentage points of THC. Gelato 41 leans slightly more indica-dominant and can stretch taller — worth knowing if your vertical space is limited. For the best combination of flavour, potency, and harvest weight, we'd pick Gelato 33.
