OGK the real deal cuts, Sour Diesel, and Chemdog D define gas for the USA. Almost every real OGK is straight gasoline make you tear up smell a whole house up easy. Sour Diesel is much more diesel fuel than normal car gasoline. Chemdog is as the name is and more chemical and solvent oriented. Newer 'gas' would be gelatti, gelato, King Louis, and things of that nature. There is nothing like real OGK cuts though are far as gasoline smell. Nothing even close to as strong. Want to find similar phenos go for SFV OGK, Fire OGK, Triangle Kush crosses from people with known legit cuts in the breeding world.
Everything like Headband, Bubba Kush, and Motorbreath etc will all be crosses and what not of the above. All are gassy smelling, but I have great disdain for any chemdog x og crosses and feel it ruins the strains no matter how many beans you pop as far as flavor and smell goes. Motor Breath is the 'new new' but I made SFV x Chemdog and released on another forum like a decade ago and while people loved the SFV selection leaner I had that tested if I remember right at 29% and circulated all in the midwest, I never even bothered improving upon it as it didn't touch either parents on their own smell and taste wise. Stick with other crosses for those strains. I've tried every cut and chemdog cut crossed...not just the one. Honestly buy anything with SFV in it just not anything from Caliconnection the swerve toon or og raskal or anyone that used their genes in their lines.
Archives supposed OGK is trash too don't even bother just another chemdog x ogk cross trying to pose as pure ogk so the smells are all muted and fucked up just like when you cross a skunk to a lot of things...it just doesn't turn out better.
