Is there any common household product that can be safely used to lower pH? I added too much baking soda to the nute solution to raise it and made it too high. I'm rather lazy, don't want to remake a mix.
Some things: -Sawdust -Composted Leaves -Wood Chips -Peat Moss edit: im assuming soil grow cheers -spliff the meister.
sure just take a bunch of sawdust and pour it in the bubbler what does not kill them makes them stronger
