I was invited to visit the facility where Empire Builder is mixed. I was really impressed with how clean and nice the compost they use was. It was a “hot” pile, and had a clean earthy smell to it.
This is my first time using the product, but the ingredients appear to be top notch. A very nice potting mix.
I’ve had good luck with Just Right Xtra. It is made in New York, and I’ve visited the facility. It has one of the most horrific mixing chambers I’ve seen.
