My bottle of ph down and ph up have both lasted me over a year each, up lasts me 2-3 years but I replace it every 2, it’s only $10 a bottle for me soo I just get it when its needed I’ll plan for it a week ahead.. I need to start investing in silica and some other nutrients I’ve been lacking in my grows, it was a big step up for me to add calmag to my shelfThanks, does the sand do anything to lower the PH? I've been looking around for sme way to improve it and buffer the PH too...
I've been searching around for something I can combine in my filter to do just that but "Gluegle" keeps geting stuck on nothing but chemicals.
Wouldn't be great if PH down is is a once a year purchase?
I forgot to mention in my video to put a coffee filter under the carbon layers for less micro carbon particulates leaching through and settling to the bottom (Not that they're harmful).
