This is by far the best ph product on the market. It is very strong so a little goes a long way.l highly recommend this product.

By far one of the best ph adjusters on the market. Very concentrated. A little goes a long way. Not all stores carry 500ml bottles, so it's nice to have indoor farmers carry a wide selection of bottle sizes.
