My keeper pheno of CSI Humboldt's 3 Queens (Wifi43 x Bubba) is one of the gassiest strains ive ever grown/smoked. But i definitely needed to hunt for that one, 1 of 4 was gas.
Most of the Cannarado stuff ive grown was on the gassy side, aside from needing to herm watch a bit more than normal on account of all the cookie and jungleboys and just generally herm prone genetics used in his stable, its been some absolute gas with most yielding pretty great too. Pretty good uniformity on the phenos from rado, not a ton of variance from seed to seed (in the packs ive bought and ran, at least) Some notable stinkers were:
GG4 x Sundae Driver
GMO x Grape Pie
Chem4/GSC x Gushers
Cereal Milk x Gushers
