What can I grow/raise on my farm that will make money?

The question you have asked relates to risk and feasibility. Given optimal conditions, almost anything can be sold, so the questions you really need to ask yourself are:
* How much money do I want to make?
* How much experience do I have with this product?
* Who would buy this product?
* How much would they pay for it?
* How much would it cost me to grow the product and get it to the customer?
Traditional commodities have more established markets and customer bases. Value-added enterprises may have a limited market base and fewer customers.
A value-added enterprise may be initiated on a smaller scale with fewer inputs than a traditional commodity.
When you have the answers to these questions, you’ll have an outline of the feasibility of making money from a product. There are many resources to help you develop answers to these questions.
