A grow-room has to have a little equipment. This is a digital kitchen scale that I use to help determine when I need to water a tricky Hoya. Weigh the plant when totally dry, and then weigh it when it is wet. Then when you just can't tell if it needs to be watered, use the scale; it won't lie. This works for quite awhile, until the plant mass grows too much and throws off your weight, but by that time hopefully the plant won't be so sensitive.
