Ive never brought from that site but what id say is that site doesnt seem all that good plus its really cheap,, A bit too cheap if you ask me!
You pay for what you get, and i reackon your not gonna get much if you go buy that site, if i was you id pay a lil extra and go with an established company that delivers results,
For example greenhouse you can get a pik n mix bag for £25-£30 and you get 5 different strains, i no its £15-£20 more but your gonna get a good genectics, And who needs 10 seeds of the same strain boring if you ask me.
