ph does not matter in organic growing!

all you need to do is add 1tsp/gal once every 3 months, and your soil will be ph’d at 7 (which is amazing for growing marijuana) every time you water. this lasts for up to 3 months, meaning you can even grow a tall sativa while never ph’ing the water

you can use normal tap water if needed, i personally use hose water. you wont get programs such as calcium lockout, and macronutrient deficiencies or lock outs, and id say it leads to a healthier plant
