I have just a lock on the grow room door and a web cam that records for 18hrs straight on my grow door so if it does get robbed I would know by whom.

IMPORTANT NOTE: Grow rooms should be locked at all times, kids should never have entry to your grow area or chemicals.
Also never have ANY GUNS near your grow area.
If the above IMPORTANT NOTE isnt followed if you are ever raided or found out not doing the above will add to your charges.
There is a BIG difference in Responsible Adult Users and just a grower.
Check out www.norml.org to better help you secure your area as a responsible grower.
