## Description

Review: Super stinky stuff that’s worth it’s weight in gold. - Make no mistake - you do not want to touch it. Haha. I’ve set this up on a timer drip system for landscaping and garden now in two different properties. It’s amazing stuff. Plants loooove it. Water early morning for just 10 minutes and within a week, plants take off. Now it’s set to water it in every 3 days. Just remember - it smells horrid - so do not plan to touch it and then not scrub yourself down (which is why ours is on an automated drip system). Have recommended it to friends and everyone has had amazing results. They have a smaller size if you want to try it out but I’m sure once you set it up so you don’t have to touch it, you’ll be hooked too. Happy gardening!
Review: Real deal - The real deal, does well, lots of tomatoes and great cuke harvest, everlasting swiss chade.

### ⭐⭐⭐⭐⭐ It works, buy some! (even if it's stinky!)
*by Z***S on February 24, 2025*

The smell is nasty, so lets just get that out of the way. That's the only negative. This stuff just WORKS. I'm obsessed. My plants love it. I put it in almost everything. Lemon trees, orange trees, strawberry plants, tomatoes, basil and other herbs. They all seem to love it and often there's almost immediate growth. It mixes easily enough. I throw some in a watering can, then fill up the can. While filling, it mixes fine. I haven't had any issues with it burning plants, but I always use it early in the AM or late at night. I recommend getting the larger size as I went through the little one too fast with my garden's size.
