I am growing some chinense seedlings in an 8X12 foot greenhouse. with our temps down here in deep south Texas, the greenhouse can be over 100 degrees in the daytime, and down to about 60 at night. This is the first year I have have had access to this greenhouse and my plants are growing faster than I have ever seen. The greenhouse, seems to magnify the light, keeps out the high winds, and still allows the plant plants to cool off at night.
Is the higher temperature spreads making the plants grow faster? I realize that in the summer the plants cannot be kept in the greenhouse, it will be too hot. For now though, it is a very interesting experiment and the results are great.
