Many people want to have a small production system with which to grow fresh, leafy vegetables that they can enjoy year round. The nutrition of freshly harvested plants is superior to similar plants purchased at your local market. Plus, by growing your own, you have complete control over the treatment of any pest and disease that may occur. The control program that you implement in your hobby greenhouse can be one with which you are comfortable. You will know exactly what has been used on your own crops, eliminating the concerns over what chemicals or other products might have been used on commercially purchased produce while it was grown at a foreign production location or during its transport to your market.
