This is my second year growing peanuts in Columbus, Ohio and I accidentally germinated so many that I started planting them out as I was out of room under my growing lights inside. When I planted out, the 10 day forecast was far different than it is now and it will possibly get down to 38 next week. I only have two outside at the moment so if I lose them, it isn't the end of the world but they're in a large grow box so I could technically bring it inside although it would be unfriendly to my back.

I can find information about the temperatures needed for germination but these plants are 2 months old and flowering already.

Does anyone who grows peanuts in a place you're actually supposed to grow peanuts have knowledge of how low the temp can get without damaging my established plants? The internet thus far has not been overly helpful. Thanks in advance!
