Booming Substrate | 3lb Coir Vermiculite Gypsum CVG Sterilized Substrate Blend | Ready to Use Mushroom Substrate Perferct for Manure and Dung Loving Mushrooms (3lb)

Im usually not a bag person and technically I didn't use it in the bag but as for quality I have had this almost 3 months and is still producing without contamination. I used it in a mono tub setup. Its colonized very fast after introducing the colonized rye seed. Highly recommend this for manure loving mushrooms like Columbian Rust. Each picture is from a different flush and still going. I didn't baby these either very little effort was put into this grow.

Great experience once again. I’ve been using Blooming Acres for a while now. Their prices are unmatched!

Came clean and sterile!

Great quality came properly hydrated no need for extra water this had improved my flushes in the past. Will most definitely be getting more.

The first time I tried this bag, but sadley will be the last. When I went to use it there was mold already in bag

Bulk substrate bag arrived 1.5 weeks before I was ready to use it. I ordered it early so I could thoroughly check it over for contamination and found none. when I was ready to use it and opened the bag I took a few wiffs of it looking for any fowl smell, found none. I mixed in my colonized grain bag 5 days ago. so far I have seen absolutely zero signs of any contamination growing and the recolonization of the substrate is progressing very fast. at this point I am 100% satisfied with the booming acres 5lb bulk substrate bag. I will update when I have any new info or after I get a first flush. for now all I see in my future is my first successful bulk grow. I decided to step up from all in one bags to give the bulk method a shot!You can spend your life reading through posive or negative reviews on products especially in this category. All I can tell you is mine came as described, free of contamination and i made damn sure I did my best to not introduce any contamination on my end. I feel my review of this product so far is worthy and booming acres did me a solid selling me a legit product.

The media could not be loaded. Substrate was sterile and completely sealed so no bacteria could get inside and my pores are doing very well now thanks to the sub

Great product
