North Spore Boomr Bag Sterile Mushroom Substrate, Manure-Based, 5 lb

The best substrate I have ever used, good yield and large fruits.

Price seems to be in little inflated to make up for delivery. But excellent product.

Great products and excellent customer service. Boomr Bag is like a shroom cheat code!

Thought this was suppose to be one of the best substrates out there to use. It takes time to grow and I’m using for personal use so I only do a few grow bags at a time. With in 6 months when I went to use I noticed bugs in my substrate. Now I kept indoors, I folded and clipped the bag tight when not in use and it was stored in the original bag, box in a closed cabinet. When I looked further I saw it was infested with gnat bugs and I felt like it was no longer usable for indoor use. It was over the return time so it was a complete waste of money on my end. If you’re using for a large grow at one time then it might be better but not in my case. I already disposed of it and did not take pictures because when I noticed this I just wanted to get it out of the house.

Original order was for 2 dung lovers bags, waited a few weeks and saw that one was contaminated. Contacted North Spore directly with my Amazon order # and they immediately sent me a replacement. Great customer service response and communication. Ordered 3 more dung lovers bags due to my needs and currently waiting to see if they along with the replacement crop up with contamination. Great response from North Spore otherwise.

Works great. 1st time doing this and it’s been a breeze

Everything from north spore is top notch. This is no exception.

This is the 2nd manure based substrate I've tried, the 1st I've had good results from. When I opened the box, comparatively, it looked like mulch. I actually thought they sent wood lovers by mistake lol I'm no expert, but again compared to my trusted brand, this one looks like it's at least 50% coco cior and the other brand looked like it was only 5%. It probably helps with aeration, and it didn't take as long to break up. Oh, and there was a rock over an inch long.... Will overlook that(minus a star tho) and update with how it performs.. I hope their equipment is OK after that went through lol An update.. 2 things. 1. It was extremely hydrated to the point that I had to carefully take the lid off early with something nearby to pour the water in before giant droplets started raining down.. Minus another star. 2. The cleanup was.. Less gross with less poo lol Will give 1 more try with a different one I'm more familiar with just bc of the easy clean up to see if there's a noticeable difference in quality. I do not recommend for things vulnerable to wet spots. Update: They must read these, the next batch was significantly darker lol. I mean, yay for this time(I hope, still too early), but it also tells me the product isn't consistent. Unless I see 3 nice tasty flushes this time, I'll stick to the other comparatively priced one. Final update: Did not see 3 flushes out of something I've seen have more. Still not a high enough poo to coco coir ratio methinks. I'm not an expert, but I'm not sure why their kits have coco coir to put on top of this, it seems to have enough lol
