From the lab panel — 17-22% THC, <1% CBD. From Canadian grower reports — 400-550 g/m² yield, fruity/sweet dominant in cured flower. moderate grow.

Smell-first: crack a cured jar and the room fills with candy-sweet fruit that sits somewhere between fresh melon and sugared citrus peel. Galactic Runtz Feminized runs 17–22% THC with a sub-1% CBD profile, so the effect lands squarely in recreational territory — relaxed but present, not flattened. Under lights or in a sheltered Canadian outdoor run, expect 400–550 g/m² after an 8–10 week flower period. The plant stays manageable for growers with a couple of seasons behind them, though she does reward consistent feeding and a clean VPD environment during the last few weeks of flower — that's when the fruity resin really stacks up.

Moderate-difficulty rating means she's forgiving enough for a second- or third-time grower but punishes neglect more than a true beginner strain would. A solid pick for indoor setups where you want a heavy sweet-profile jar filler without chasing a finicky cultivar.

Growing Galactic Runtz

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-550 g/m². Plants typically reach 80-150 cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Flavor, Aroma & Terpene Profile

Galactic Runtz features a fruity, sweet terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually.
