Squirt is a terpene bomb in plant form. Humboldt Seed Company found it in a 10,000-plant phenotype hunt, and the line is known for one thing above all: a sweet and tart grapefruit nose that sticks around longer than most. This Sativa-dominant feminized strain is listed at 20% Indica / 80% Sativa with an average of 20% THC.
The effect is energizing and functional, a clear daytime buzz that lets you keep moving. Buds come in a mix of purple and green, with color that varies from plant to plant while the aroma, flavor, and chemotype stay consistent.
The breeder calls Squirt an extractor’s dream, and the 50-day bloom makes it one of the quickest Sativa-dominant photoperiods around. Grow it for bright citrus terps, a fast finish, and resin that holds its flavor.
Squirt Genetics: Blueberry Muffin x Tangie
Squirt comes from Blueberry Muffin x Tangie. The original keeper was labeled BBMxTang #118 during the breeder’s Phenotype Mega Hunt. Humboldt Seed Company then pulled the parent lines from its genetic preservation library and backcrossed to lock in the plant’s standout terpene output.
The line is listed as Bx5. The aim of all that backcrossing was consistency: each seed should deliver the same grapefruit chemotype, even if the amount of purple anthocyanin color shifts from one plant to the next.
Aroma, Flavor, and Effect
Squirt smells like sweet and tart grapefruit, juicy and bright with a sugary edge that softens the sour snap. Tangie brings the citrus zest, Blueberry Muffin rounds the edges with sweetness, and the mono- and sesquiterpenes keep the scent lingering well after the grind.
On the palate it tastes like a ruby red grapefruit dusted with sugar, eaten cold on a hot morning. The citrus holds through the whole draw instead of fading after the first hit, which is exactly why extract makers chase it.
The effect is listed as energizing and functional. Expect a clean, upbeat lift that sharpens focus and keeps energy up without scattering the mind. It fits morning chores, outdoor activities, and creative work.
Growing Squirt Indoors and Outdoors
Indoors, Squirt needs only about 50 days of flowering, a short run for a Sativa-dominant plant. Expect some stretch after the flip, so top in veg and train the canopy flat with LST. Cooler nights near the end can bring out the purple in plants that carry it.
Outdoors, harvest lands between September 20 and October 5, early enough to beat most autumn rain on the North Coast. Give plants full sun and steady airflow to protect the terpene-rich flowers.
For extraction, harvest at peak terpene expression and process fresh-frozen to capture the grapefruit nose. Expect visual variation between purple and green plants, but the same chemical profile across the line. A gentle hand trim and a slow, cool cure keep the grapefruit bright for months.
