## Customer Reviews

### ⭐⭐⭐⭐⭐ Works for a Variety of Plants
*by K***K on July 7, 2025*

I’ve used this enough now to confidently say it works. Cyclomen LOVE it! Philodendron also love it. I also use it in my vegetable garden. It’s great for squash, cucumbers, peppers, and tomatoes. It seems to help vegetable plants root better. My garden is in an old water trough, and the plants weren’t growing well until I started using the liquid kelp. It’s helped the plants get big enough to start producing.

### ⭐⭐⭐⭐⭐ Always in my greenhouse
*by P***R on June 25, 2025*

Works well and smoothly. Better growth, but gently so rather than a "rush` of growth.

### ⭐⭐⭐⭐⭐ Amazing rooting stimulator
*by B***O on August 28, 2024*

Im not sure if its been mentioned yet, but this stuff is amazing rooting stimulator for cannabis. Seaweed and kelp are full of incredible rooting hormones. I use this stuff at 10ml per gallon in conjuction with 20 ml per gallon of Rhizotonic and my cuttings and baby plants explode with growth, and thick, healthy roots.
