Review: Works as should and fresh - Great stuff and great container
Review: Works great. - Works great. Forgot to get more nutrient before starting another batch and got this expedited. Bubbles slowed way down and I was darn near a stall. Then the package arrived, I dosed and those yeast are going crazy now, but with no cap because I put bentonite in up front. Looks like I have a good one going.

Great stuff and great container

### ⭐⭐⭐⭐⭐ Works great.
*by T***L on October 14, 2025*

Works great. Forgot to get more nutrient before starting another batch and got this expedited. Bubbles slowed way down and I was darn near a stall. Then the package arrived, I dosed and those yeast are going crazy now, but with no cap because I put bentonite in up front. Looks like I have a good one going.

### ⭐ Is this a joke???
*by A***R on June 18, 2025*

Idk how to feel honestly. Hopefully it’s still good product. It looks like it’s been opened and used before according to everything I’ve seen…. Honestly not a fan about that. Edit* Will be adding photos every time I receive a damaged product.
