greenhouse seeds cheese - finding a keeper.

I heard that you can find a close match to 'UK cheese' in the GHS feminised seeds but you need to grow out a few packs to get it. Does anyone know what to look for?

I also heard about double serrated leaves being on the original UK cheese and I have seen some on my mate's GHS cheese plant, is it the 'keeper'? If so I will take a cut or two

you wud have to grow about 50 or so to find the real one i have the exodus and psychosis i tried big buddhas blue cheese and it sucked big time
