Good product overall
I thought this product worked well. I added it to my compost pile in Utah in mid summer. I felt like it sped the composting process up and helped make great fertilizer for my garden. Its hard to tell what impact it had or whether the compost would have broken down anyways.

Works fast!
I’ve used Roebic’s Compost Accelerator in my compost pile and was genuinely impressed with how well it worked. It sped up the breakdown process noticeably, even with a bunch of grass clippings, veggie scraps, cardboard and leaves. I’ll definitely be buying this again. What I really appreciate is that there’s no harsh or chemical odor..it’s clean, easy to use, and completely safe for the garden. This blend is super effective on both green and dry material, making it perfect for year-round composting. Highly recommend!

Does not speed up composting
Slowly helps breakdown compost. Bottle covers 1 30 gallon trash can of debris. No more effective than shredding debris, then composting.

Best accelerator
This composter has helped me to compost quite a few things for my garden. It really accelerated the composition, I could see vapor coming out of my compost within 2 days after application.
