### ⭐⭐⭐⭐⭐ great for water retention
*by D***N on June 11, 2025*

I used these to clone my plants and they do a wonderful job of keeping your clones well hydrated. I suggest using this over other products. It has been really effective and a great away to make it an easy experience when it comes to cloning plants. I dont have to stay on top of the watering multiple times a day.
