Anyone using Blumat Watering Stakes..? I know they water when THEY think the plant needs water, but I thought of hooking up a gravity fed bucket system for watering/feeding my indoor soil grow. Would put an on/off valve inline, so I could decide when to water and not the watering stakes.. Getting lazy in my old age and those Halo Rings just do not excite me for some reason . Would be good for an auto watering system too if hooked to a pump and timer I think.. Thoughts?
