alrighty well thanks for the answers fellas.....also without a meter(due to lack of finance at the moment), is it still possible to go hydro, just kind of do 2/3 3/4th strength nutrients and know your signs on the plant for what is wrong? i have a well collected folder of information that i can refer to for almost any problem(gotta love reading), so i feel without a meter i could still achieve a successful first grow and first hydro.....and im also saving up as much as i can to get a meter asap heh.
