Gastronaut
Gastronaut is a hybrid strain crossing Motorbreath #15 with Zero Gravity #60. It's gained traction across multiple markets as different cultivators (Bloom County, Platinum Farms, Bostica, Flow Gardens) release their own cuts, which likely explains why classification varies so widely by retailer — the same breeder's product line lists both an "Indica" and a "Sativa" version under different sub-names. The name plays on its familiar-but-otherworldly aroma: pungent diesel leads with earthy spice and black pepper, while citrus and garlic undertones round out a savory nose — which makes it easy to distinguish from the sweet flavors of the similarly named, but genetically unrelated, Gastronought strain.
Fans of this hybrid describe the effects as uplifting and euphoric, with many noting a wave of creativity that settles into full-body relaxation without heaviness. The flavor follows the nose closely, delivering diesel and citrus on the inhale with an earthy, herbal finish.
Gastronaut is a moderate-difficulty strain that stays compact at 3–5 feet indoors, making it a good fit for growers with limited vertical space who don't mind some lateral spread. Outdoors, it stretches to around 6 feet and thrives in warm Mediterranean climates with temperatures between 68–80°F. The dense, resinous bud structure means you'll want to keep humidity around 40–50% during late flowering to avoid mold in those tight colas. Flowering takes roughly 9–10 weeks, and growers often report medium-to-high yields when conditions stay consistent, with some phenotypes showing purple hues under cooler nighttime temps.
