They should be about equal to most, but i think their catch is "organic"( i might be wrong).. anyway, most nute lines use multiple bottles, i try what i can when i can but i usually fall back to the Lucas one bag formula start to finish, being under LED i do have to use calmag and silica tho... the shipping from oregon to tennesee was about 27$ for one of our members and they quoted me 25$ in colorado.. not bad for a pricey line, use what you need and throw the rest?!!?!
