This one should be a no brainer.
I am sitting almost directly between Kalamazoo and Mount Pleasant.
Not that anyone asked... lol
I do like the MedMj around here. My hydro store is amazing for most things. Under MSRP, AND get 25% off.
Grow tents, drying racks, light hangers, any environment controllers, dirt, perlite. Things you should avoid buying at most any hydro store.
Find all of those cheaper on amazon/somewhere else on the internet.
My biggest money saver will be dirt. Its about half price online, ships free w/amazon super saver.
I Will be buying the ingredients used to make a soiless mix, and mix it myself. Still sits around half the price.
Doing it mostly so I can dial things in more, for plant specific needs.
