Reply To: Tomatoes in Poly Tunnel

[RandA]

I find that to give a rough estimate the night time temperatures in our tunnel ( 14’x 36′) are approximately 2 degrees c warmer than outside. If you have sunny days the temperature in the tunnel in the day time can go really high 40 C++ if the doors are not open. I agree with Don that the tomato leaves look like sun scorch I would not worry either but if a cold night is forecast then fleece may help. We are not far from you across the water in south wales and I have put my tomatoes out they are doing OK so far. Hope that helps and good luck
