Marijuana Moisture Level

Hey, I just got a soil moisture reader and I didn't know what level to water it at. The details on the back of the package have different specs for like 40 plants. None of them are cannabis indica, of course. Does anyone know if there is another common plant that I can model after a marijuana plant? Or even less specific should I let it get to the dry, moist, or wet section on the read?
Anything helps
Thanks.

P.S. It is a hog plant that is in its second week of 12/12 light. Part inside and part outside (when its not raining).
lol these are cool

take it back to the store .. water by weight or scratch the surface with your finger. Once matured a month or so, when the soil detaches from the sides, water

i don't use a metter i wait till my soil drys out
