Ok, so in a little while, Im gonna go outta town for about a week, and its gonna be the first time Ill be away from my plants. Now, Ive heard of the tray method of watering, but Ive never really had to use it because I live in a humid environment, but I was wondering: could I use the tray method to water my plants for the week that Im gone? Cause Id like to avoid getting someone to plant sit, Im too scared, lol.
