hi everyone. i just started my first indoor grow in soil and i am trying to keep a low budget. i happened to find a bottle of "pH up" in my closet that is used for raising the pH of hot tub water. it is one hundred percent sodium bicarbonate. i was just wondering if anyone knew if this is safe to use in my water for my mj plants if i need to raise the pH. also is using gardeneing pH up and down products a cheap and effective way of controlling the pH of my water/ nute solution? thanks for any responses in advance!
