Baking soda, was used by most growers for decades from the 70s and on just as pickle juice was. Who doesnt hsve baking soda in the fridge soaking up odors or pickle juice. Easy up snd down supplies.

Don’t even go there @ChittyChittyBangin, DeeGee will make you go to plan B fast…They do not seem to have sophisticated logistics…. On the other hand, they almost always have a workable plan B. Sinister programming…

Garden lime Will increase pH if you need calcium. Eggshells or oyster shell flour will help a little less .
