Frost protection for outdoor plants

[Grower2020]

Hi all again. My feminised seeds trial was a complete success and I have also increased germination %.

Just a matter of covering them over night, we use old blankets or bed sheets. It keeps the misty dew off of them and prevents it from freezing!!
