G Tank strain guide
G Tank, also sold as Gas Tanker or Gas Tank, is an indica-leaning cross of Gas and Sour Diesel. As the name suggests, it smells like fuel, with citrus and pine on top, and people mostly describe it as a heavy, relaxing smoke.
Where does G Tank come from?
Two strain databases both list G Tank as a cross of Gas and Sour Diesel. One strain database ties the Gas side to All Gas OG, a strain that also goes by the nickname Gas, and credits the cross to the breeder Agri-Kind. Another database doesn't name a breeder, so the breeder credit rests on a single source.
It's usually sold as an indica-dominant hybrid, with one strain database putting it around 70% indica. The name is simple enough: a strain built to smell like a tank of gas.
What does G Tank smell and taste like?
Expect diesel first. Listings describe a sharp, sour fuel smell with lemon and citrus, plus pine, earth and herbs underneath. The taste follows the same path, gassy and sour with a spicy, woody finish.
One strain database's terpene results put limonene at the top, followed by caryophyllene and myrcene, though its own description calls myrcene the leading one. Either way, that trio explains the citrus brightness, the peppery bite and the earthy base.
G Tank effects: what people report
People most often call G Tank relaxing, sleepy and hunger-inducing. One strain database describes a high that builds over a few minutes, starting with a calm, focused lift before settling into a heavy body feel. Some people also mention feeling creative or happy early on.
These are experiences people report, not promises. It depends on the product, how much you have and your own tolerance. Dry eyes are the most common complaint, and some people mention feeling anxious.
How strong is G Tank?
Published numbers vary. One strain database lists G Tank at about 15% to 21% THC, and another database puts it at around 22%, with little CBD reported. Infused pre-rolls sold under the name test much higher, but those are concentrate products, not plain flower.
If you're new to it, start with a small amount and wait before having more. Check the label on your batch, and our guide to reading cannabis labels explains what the numbers mean.
Buying G Tank in Canada
You may see it as G Tank, G-Tank, Gas Tank or Gas Tanker. Be careful with similar names: Oil Tanker is a different strain, and some vape products called Gas Tank may not be the same cultivar at all.
Check the lineage, THC and CBD numbers and the packaging date on the label. Gassy strains keep their punch best when the flower is fresh.
G Tank vs Sour Diesel
Sour Diesel is one of G Tank's parents, and the shared fuel smell is obvious. The big difference is in the feel. Sour Diesel is known as an energetic, sativa-leaning daytime strain, while G Tank leans indica and most people describe it as heavy, sleepy and good for the couch. G Tank also adds more pine and earth to the diesel. If you want the gas smell with a lively, upbeat feel, go with Sour Diesel. If you want that same fuel smell at the end of the day, G Tank is the closer fit.
