If done correctly, a plant can easily yield one pound of medical marijuana.

Your yield will depend on your growing facility investment, knowledge base, and help structure. There are lots of dispensaries or affiliates that offer cannabis cultivation classes. Even a simple comm. college plant science class can be a big help.

Also, smoking the same medical marijuana day in and day out will eventually cause "strain burn" or a tolerance. Try to find more than one strain for your particular condition.

Good Luck to you
