ProMix makes a lot of different products, too

People have different results with the same product for a lot of reasons. Some might be using it for indoor plants, left in a pot for years at a time. Some might be growing outdoor plants for just a few months in summer. Some live in rainy climates, others in deserts. Some are growing cacti, some tomatoes. So the results people report with any product can be very, very different. Nobody's right, nobody's wrong. We just all have favorites, and we've learned to work with and like a particular product, in our particular climate, etc.
