Testimonials
Our happy customers have a lot to say about our products and services!
Owning a gardening retail store is a tough business in today’s age, which means we have to buy products that can move themselves off the shelves. We took a chance on adding mushroom supplies from Left Coast Wholesale and I’m glad we took the chance! Our mushroom supplies are bringing in new customers as the interest for these products continues to peak. With all-in-one bags from Left Coast, anyone can grow mushrooms!
Adam Berkey
from Get GrowingI’ve had a wonderful working relationship with Left Coast Wholesale for over a decade. Naturally, I may show them a little favoritism, but I can say without bias that their new line of mushroom cultivation products are second-to-none. Higher quality inputs than the competitors and more robust packaging to ensure contamination-free products. From micropore tape to pressure cookers, all-in-one bags and still air boxes, Left Coast Wholesale has everything you need to bring mushroom cultivation to your community.
