I have a very secure garden with the full setup. All my plants are fertilized and well-watered. Three times I have attempted to grow hemp, and three times it has disappeared before reaching maturity. Colonel just planted 9 seeds of hemp in a new planter, and three of the plants have already disappeared. It is impossible to access my plants without a door code. Noone is stealing them. All other crops grow and mature just fine. This is on US Survival.
