HydroSpike works well for watering smaller sized plants. Isn’t this little guy pretty cute?? Healthy and green with automatic plant waterer – HydroSpike
When I first set these up (following the instructions on the package), I didn’t see how they would work. But, after a time I noticed the water level in my reservoir bottle beginning to drop. I was amazed. The flow rate is slow, so if you have a very large pot you will need more than one HydroSpike.
