Yeah I planed on pickin up some meters for the next grow. For Ph last time we just did it the old school way where you mix the soil and water boil it create a percipatae then use a ph paper like you would for any other liquid. The Ph was for the most part neutral the entire grow. This was really done by the seat of the pants here, watered when it looked to need it with good old wegmans spring water, and just given some worm poop every monday lol.
