I think the plants get very stressed when they are exposed for more than 3 hours in the sun... that's what is happening here. As soon as they are shaded they are back to normal. Your greenhouse is best! They get the sun but not directly beating on them,.. the plants enjoy the high temps!
Hugs and Kisses sis 🥰🌺🤙!
They do seem happy enough! The corn is sprouting!🤗😘🌸💕
