Skunk #1 is sativa and takes a lot longer than indica to mature.

Last summer (I'm in the UK too) I had some Afghani (indica), and some skunk #1.
I'm not sure exactly when they finished but the Afghani finished just fine but the skunk#1 started to go mouldy so I had to chop it before it was mature.
It was still an OK smoke, it got me stoned but I didn't get that much of it.
The buds were sparse and not very dense at all, there were more pistils than buds!
