dopeseeds deal with alot of offical seedbanks and they do ship to the us they are orig packs and they have alot of seedsbank products that dont ship to us so just go through them and they will ship
the best nutrients hands down is the techna flora system pre ph balanced been on em for about 1 year and never had ph up or down problems leaf burn ect.
that system is only good for very small plants i had that one and my plants outgrew that shit in 3 weeks i know its cheap but invest properly or dont waste time with the bullshit
