Hello Nzbushninja, welcome to the AFN family!
Your question is very plain. This is like me asking "how much petrol does your car use?" you can't answer it until you have all the variables. The exact same equation applies to this question you've asked today. We need to know the variables to be able to give you an approximate answer. Variables include, but are not limited to: time of year, location, altitude, temperature, humidity levels, soil quality (ph testing/bug tests etc..), hours of direct sunlight, any local pests/bugs, nutrients.
After you've managed to collect this data. You'll then need to select a strain of Cannabis suitable for your conditions,climate & environment. If your climate is hot, you'll need to select a heat-resistant strain. If your environment humidity is too high, you'll need a mold resistant strain: and so on.
AFN have an excellent viable and constantly updated source of information with thousands of active members.
Once you've summed up and explained your climate,conditions and environment members might be able to assist you better by suggesting strains suitable for your climate and estimating an approximate yield.
