I'm a firm believer in moisture meters, for SOIL. Mine has a 8 inch probe. With several plants...I noticed some plants want/need water after 12 hours, other plants nextdoor, don't need water for 24-36 hours. Go figure?

Easy to use, cheap. Goes to the BOTTOM of a 10 inch pot. Three possible readings: Wet-Moist-Dry. I don't water until it reads DRY.... KISS principal growing....:smokin:

I don't like to get my fingernails dirty....ostexcuseme:
