Zero Gravity is one name with three launch pads. Each origin below is its own cross, and none of them share a flight plan.
Origin 1: Clearwater Genetics' version, selected by Shauncron, crosses GMO with Oreoz. This is the one most menus mean. It runs garlic and fuel up front, with earthy depth, sour citrus, and a sweet, hashy finish. Potency is the payload: lots commonly test in the 20s, with standouts near 30%.
Origin 2: North Genetics pairs a Holy Grail Kush female with a Smurfzilla male. The breeder describes large, dense, resinous buds with an herbal, earthy, woody nose and skunky-sweet undertones. Its listed effects are creative, euphoric, happy, and relaxing.
Origin 3: An older listing gives Hash Plant x Northern Lights #1, with sour citrus and earthy herbs and a milder 13% to 21% THC range. No breeder is named for this one, so treat it as a separate branch, not a phenotype of the other two.
What the three share is the trajectory. Accounts of the GMO cross describe a euphoric, weightless float that lands as a heavy body high, while the Hash Plant version is reported as a lifted, giggly head that ends on the couch. Check the label to learn which rocket you're boarding. The ceiling can be interesting. The couch can be mission control. Gravity gets the last word anyway.
Know which Zero Gravity you're fueling before you plan the room, because the grow data splits by breeder.
North Genetics' cross flowers in 56 to 63 days and was only ever sold as regular seed. The breeder calls it a heavy yielder with a medium-to-large stretch in flower, so topping or training earns its keep. It's listed for indoor and outdoor runs.
The Clearwater cut runs longer, at 60 to 70 days, with a dense, cookie-stacked structure. The original is a selected cut, so most seed on the market is a cross built on it. Examples include Clearwater's own feminized Runtz x Zero Gravity, Greenpoint's regular Zero Gravity x Star Dawg, and Tiki Madman's feminized Zero Gravity x Devil Driver.
No grow information turned up for the Hash Plant x Northern Lights #1 version.
