Hawaii - If you want to grow mj indoors you absolutely MUST know your pH. If you can't afford the $97 meter, buy a liquid test kit for $9 or get some litmus paper.

pH is like the foundation of a house. You can build the most beautiful house in the world but, if your foundation crumbles, so will the entire house.

The purpose of flushing is to clean the soil and correct the pH. If you don't know the pH of your flushing water, how are you going to use it to correct the pH?
