i can buy nice healthy clones for $10 each so right now i have some bigbud clones. i would love to clone and get 10 more of them,is it hard and costly to be successful? i have most of the stuff i think? i have 7 inch humidity dome ,fish tank heat pad ,cfl's ,so i need rock wool and some root gel? any thing else? is it worth doing or should i just buy them?
