Gelato 33 Fast by Advanced Seeds – Fast-Flowering Feminized Cannabis Seeds with 24% THC

Gelato 33 Fast by Advanced Seeds is a photoperiod feminized cannabis strain engineered for speed without sacrificing quality, delivering dense, trichome-rich buds in just 45–55 days of flowering, perfect for growers who want fast results with high potency and exceptional flavor.

Worried your grow is taking too long and you’re missing the ideal harvest window? With regular strains, you’re stuck waiting weeks longer, risking mold, pests, or bad weather—especially if you're growing outdoors or need discretion. That delay kills momentum and increases stress.

That endless wait turns into anxiety. You’re checking every day, hoping the trichomes turn, but the stretch keeps going and your space feels cramped. The smell builds, your schedule gets tight, and you start doubting your setup. That constant pressure makes the whole experience feel like a chore instead of a chill ritual.

Meet Gelato 33 Fast—a strain bred to cut the wait and maximize control. With a flowering cycle of just 45–55 days, you gain back time, reduce risk, and harvest cleaner, more resinous buds. Its compact indoor size and early outdoor finish in early September mean you beat the autumn rains and keep your grow low-key and efficient.

More Discretion, Fewer Worries

Gelato 33 Fast keeps a low profile without sacrificing yield. Indoors, it reaches a manageable 0.80–1.10 m (2.62–3.61 ft), making it ideal for stealth grows or limited spaces. Outdoors, it grows vigorously but finishes early, reducing exposure. Its dense, hard buds are easy to store and handle, and the plant’s natural resistance to mold and pests means fewer surprises. Whether you're in a closet or backyard, this strain respects your need for privacy and peace of mind.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of Gelato phenos, but the Fast version from Advanced Seeds changed the game for me. Last season, I ran a 4-plant SCROG in my 1.4 m² tent, and I was blown away by how fast it finished—just 52 days from switch to harvest. I used a 600W LED and kept it simple: organic soil, light defoliation, and a solid bloom booster. The buds were dense, frosty, and smelled like citrus cookie dough straight from the oven. I didn’t need to chase big yields—this strain gave me quality, speed, and peace of mind. My only tip? Don’t rush the cure. Even though it’s fast to grow, let it rest 3 weeks in jars. The flavor deepens, and the high becomes silkier. This one’s a keeper.
