The glue (GG#4) is a clone only strain, even if someone had a seed to sell you, don't be fooled into paying for it, its bagseed and lies...
Find a decent dispensary or similar, may require a road trip.... Its how I plan to acquire GG4 and Deathstar this summer...
I have switched off to the gorilla seedbank for my last several orders... They got decent pricing, the shipping (choose the safe shipping) is on par w/ other UK seedbanks, and the customer service is downright stellar, plus lots of social/community interaction...
I actually have a set of 20 seeds should be in the mail right now, from winning a RUI contest from the gorilla... literally saved my from placing an order (which I would have this weekend, now I got a little more time

Critical Jack ftw )
