I watered my succulents today and was able to use C-GRO for the first time. I heard about this product a few weeks ago and it sounds like a great alternative to chemically manufactured products. I'm only watering succulents like Haworthia and Gasteria in the winter and adult cacti will stay dry until May. In the spring there will be many more plants to try C-GRO on, but until then I will be able to see some growth with the non-cacti succulents.
