Kings with excellent strains… and seeds

I`ve done quite a few grows with autos and was always happy with what I had had until I grew a sample seed from your company called the massive midget, it was a sample from a UK company called "Maryseeds", i grew the plant under CFL's and did an LST and my god it was the best plant I`ve ever grown, i got just over 56g of top quality bud.

Everyone I know said *** genetics were the best but Heavyweight seeds are kings in my opinion, actually I was disappointed with ***, in the future I will only buy your seeds.

Thanks for creating such excellent strains and seeds!!
