Review on Keep Your Plants Hydrated With JUSHACHENGTA'S 8 Pack Automatic Plant Waterers: Ideal For Indoor And Outdoor Use by Daniel Reeder

I really wish these were more reliable, because they are really cool when they do work. I had a couple hanging plants that were watered solely with the spikes for about 2 months, but eventually they stopped working and I only noticed when the plants' leaves started drying out. A couple others I tested would lose seal and let air into the spike, then no more water gets in. I never got those ones to work at all!The ones that stopped working on the hanging plants (ivies in 6" pots) were still pulling up water, but I think most of it was basically evaporating right through the soil before the plant could use it. The soil was bone dry except for right against the spike; the water just can't diffuse through all the dirt that effectively. One plant had tenaciously rooted all over the surface of the spike to the point that the spike was very difficult to remove from the dirt! So again the spike is pulling up water, but only a few greedy roots right next to it were getting all the water so other vines in that pot died.
