Can I grow multiple crops with my greenhouse tomatoes?

Can I grow various crops, e.g. tomatoes, peppers, cucumbers, lettuce, and strawberries, all together in the same greenhouse? Or will this create an unmanageable problem for me?

It is best not to grow multiple types of crops in the same greenhouse. Each has its own optimum environment (temperature, light, humidity, etc.), fertilizer, and water requirements.

You could, however, grow a main crop, like tomatoes, and have a "few" of something else, just to try out. But, in that case, the system should be optimized for the main crop. If you decide to grow a larger scale of more than one kind of vegetable, it is best to grow each in a separate greenhouse which will be set up for the required conditions for that crop. But, be sure there is a market for that second or third crop. Tomatoes are the easiest to sell. Other vegetables will sell well in some areas, but not in others (for example cucumbers and lettuce).
