Where Fire OG Comes From
Fire OG is usually described as a cross of OG Kush and SFV OG, the San Fernando Valley OG. Weedmaps describes it as an even cross of Raskal’s OG Kush and SFV OG Kush by The Cali Connection, and notes that versions from other breeders differ. Purple Caper Seeds is reported to have crossed a 5K OG Kush cut with Fire Lady, and Humboldt Seed Company has released a related line. Another account ties the strain to OG Raskal Genetics.
These differing stories mean Fire OG is less a single clone than a family of OG-based selections sold under one name. Sources broadly agree on the indica lean, putting it at roughly 60 to 70 percent indica.
The name is a nod to how strong and flavorful it is. Fire OG has been a mainstay of California and Pacific Northwest dispensaries, particularly for people who want the classic OG profile at a high THC level.
Fire OG Effects: What It Feels Like
Fire OG offers a fast climb into a warm, happy high with a clear mood lift. After a short while the body relaxation arrives, loosening muscles and slowing the mind. The effect is weighty but usually not foggy.
It works well in the evening for dinner, TV, music or conversation with a friend. Higher doses bring sleepiness, and the strength means newer consumers should be careful. Some people find it uplifting enough for a relaxed afternoon in small amounts.
Fire OG Terpenes, Aroma and Flavor
The smell is classic OG: pine, lemon, fuel and damp earth, with an almost cleaning-product sharpness in the best jars. SFV OG adds the bright citrus and pine notes, while OG Kush supplies the earthy gas.
The flavor is piney and citrusy on the inhale with diesel and earth on the exhale. Myrcene, limonene and caryophyllene are the terpenes most often reported, though levels differ between growers.
- Myrcene: earthy, musky and herbal, also found in mango and hops
- Limonene: bright citrus, also found in lemon and orange peel
- Beta-caryophyllene: peppery and spicy, also found in black pepper and cloves
Terpene levels vary from grower to grower and batch to batch, so check the lab label on the package. Learn more in our guide to cannabis terpenes.
Side Effects and How to Use Fire OG
Dry mouth and dry eyes are the most reported effects. Drowsiness and couch-lock are likely at larger doses, and some people feel dizzy or anxious if they overdo it. Start with a small amount and avoid driving.
With Fire OG, as with any strain, a smaller dose usually avoids anxiety or grogginess. Our cannabis safety guide covers what to do if you take too much.

Growing Fire OG
- Difficulty: Moderate to difficult
- Flowering: 8–9 weeks
- Yield: Medium
- Height: Medium to tall
- Environment: Indoor or greenhouse preferred
Fire OG tends to be a moderately stretchy plant with dense, resinous flowers. It does best with careful humidity control, and in wet western Oregon and Washington autumns an outdoor crop is at real risk of mold, so indoor or greenhouse growing is safer. Because different breeders sell different Fire OGs, flowering time and yield vary.
Home-grow rules depend on the state: adults can grow at home in states such as California (six plants per residence), Michigan (12 per residence) and Oregon (four per household), while Washington and Illinois allow home growing only for registered medical patients. Check your state in our cannabis laws by state guide before you plant anything.
