Dude - you're in luck.

I haven't seen them in awhile, but one of the people from Buddha Seeds is a member here.
If you locate one of their posts & reply to it, maybe they'll answer - think their username was simply Buddha Seeds - not sure if it was hyphenated or something.

This is their main website where you can find some more info on the individual seeds in that mix pack.

I read the descriptions for White Dwarf & Red Dwarf, but they don't give expected sizes.
If I were you, I'd use the contact screen on their site & ask them what's up. I can't give you any grow advice because growing is illegal in the UK & against our company policies - I work for Rhino Seeds & Gorilla Seeds (site sponsors - you can find our banners at the top of the screen & links at the bottom) so I have to go by those rules.

But Buddha Seeds is in Spain where it's legal - you might be able to get some grow tips from them. They were handing them out freely on this site while they were posting.
