New grower with some questions, I just ordered a hydro system online. I am new to growing, i currently have 3 plants in the flowering phase, they are in soil. My question is the guy I bought from said its a bubbler system not a drip system. My question is what is the differences, its a 6 unit setup how will the plants get nutes and H2O through the reservoir to each individual plant? . He says it does not use a water pump it uses a air pump. Can anyone explain what I just purchased. LOL
