Review on KiKiHeim Frog Plant Watering Spikes - Terracotta Self Watering Planter Inserts For Slow Release Watering - Set Of 4 Spikes, 3.4 Oz Capacity by Davaun Pritchard

I have put three of these in my plants in my classroom. The students love seeing them peeking out from between the leaves. I have one at home, as you can see from the picture. There are a few plants at school that need to have consistently damp soil. When I fill up the frogs, the water generally dissipates out within a day or two. I don't know how well these would work if you are going to be away as they seem to drain out within a day or so. They do keep the soil damp for the most part, but I am adding water every couple of days. As a decoration, they are fun and cute!
