Aqua Globes: Tested by filling the globe with water and inserting it into the plant to see if it releases water
"Once they were in the dirt, bubbles started making their way to the top. The bubbles indicate that water is leaving the globe and going into the soil. As the dirt becomes dry, it releases oxygen into the globe, which releases the exact amount of water your plant needs."

Self watering Plant Spikes: Tested by attaching a bottle to the spike and filling it with water to see if it releases it
"This system is so easy to use, so even if you don’t have any experience with a product like this one, you will be able to install it quickly and easily. All you need are wine bottles or plastic ones (with a 2.8cm diameter mouth) that you will need to drill or cut at the bottom for better control of the flow. Put the bottle in the spike and adjust the speed of the flow with the regulating valve. You can choose between slow and fast speed of dripping water according to the time you’ll be away, so your plants are always watered perfectly, without the excess of the water."
