anyone ever tried osa 28 silica? i do flood and drain and i read it only last a couple days in a res (i only change the res once per week) im wondering if even if its applied once a week on a new res change if it will still be effective. anyone have any before and after osa pics?
the main reason i want to use it is to try and get thicker clones on my mom plants along with blowing air on them
