I haven't tried any of the OG Kush strains yet. This one grows in a really strange way compared to my other plants. Few, large leaves that develop slowly, and _A LOT_ of stretch occuring the first week after 12/12. They say its supposed to fill out in flower - we shall see.
Somewhere down the line, i'll be planting a DinaFem OG kush too, so that will give me a chance to compare. I also have a few RP: The OG #18 in my seed collection, which is a specially selected pheno of the OG kush - will be planting one of these very soon.
