I use herbies head shop, really friendly staff, willing to help you in the best way they can legally. they always have awesome offers, every order gets extra seeds free, germination is always spot on too. fast delivery to mainland UK so im sure Ireland will be pretty speedy too. ive been using them for a couple of years and would never go anywhere else. hope that helps, if that fails breed your own!! thats the best option in my opinion, always nice to have something a bit different. Its a fairly easy process too and you will save thousands on seeds, there is loads of great threads on here on the subject.
