Growing vegetables in Your Greenhouse

摘要

Growing vegetables in your greenhouse has great rewards and is not that tough once you know what they need. We should first look at some requirements for growing warm weather crops, such as tomatoes or cucumbers. Most important is light and heat. Without enough of either, your crops can take as much as twice their normal time to mature. You must have 8 hours of light per day. Temperatures should be 70°- 80° days and 60°- 65° nights. Plants with warm roots can stand air temperatures 5° to 10° cooler than recommended. Heating cables under containers and in beds can provide this kind of protetion.
