is it too late?

Hi everyone. My mother wants to plant a watermelon seeds in our greenhouse, but she is not sure if it is not too late. Now, days are a bit cold in my country (temperature is about 8*C at night) so I am worried if it will grow. What do you think? How many days does it sprout?

Do you have electricity for grow lights and heat in that greenhouse?

To grow it successfully, you need a lot of heat. I have to say it is a bit too late.
