I'm doing my first outdoor grow. I have 16 in the ground scattered throughout my plot. I tried using a GPS app on my phone but it didnt turn out as well as I hoped. I need to label and mark where all my plants are but do it discreetly since its my moms property. I dont need her walking around and spotting them. How do you guys do it? So far I have sticks set up but I feel when I put the rest(~20) out, I wont remember where they all are.
