Peas are a cool weather crop, but the seeds take a long time to germinate in cold soil. The length of time it takes for a pea seed to germinate depends on temperature, moisture and age of the seed.eas are a cool weather crop, but the seeds take a long time to germinate in cold soil.

Recommended Dimensions. Twitter's recommended dimensions for header photo is 1500px in width X 500px in height. But the size that really works well for me is (which I'm currently using this 2016): 1500px (width) X 421px (height)
1. Selecting an Image. Original image size cannot exceed 1252Ã626 pixels (with a max file size of 5MB). Twitter does not specify a minimum size, but anything smaller than 640 pixels-wide will appear poor quality. The header image is a horizontal bar, so any landscape-oriented photo will look better than a portrait (vertical) photo. Although you can resize the image, it doesn't appear to align 100% accurately.
