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. Any have any experience on how well it works or anyone have any before and after or comparison pics of OSA?
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, also i use veg+bloom nutrients by hydroponic research
