Hello I am just getting started with dry ferts (thanks to Orlando from GLA) and now going to use the PPS Pro Solution. I will be using a 500ml bottles to mix in (macros and micros). The question I have is how long is the mix good for once I combine each of them in the bottles? Do you need to refrigerate or anything special with it once it is mixed?
Maybe I should just continue the dry micros then, it's easy enough to do anyway. Makes sense to do the work of mixing all the macros for an easier regime (disclaimer: easier for some of us), but it sounds like it was all in vein for those that got fungus in their trace. I'm betting my luck will give me fungus in my micros as well.
