when you switch to 12/12 what should your tempreture be when your lights are turned off??

I like it no less than 18 degrees,

Just the same as Veg mate. Around 21c to 23c is sweet.
A little bit higher and lower won't cause problems but try and avoid if possible

Temperature:

Your plant's will grow healthy in temperatures between 21c and 29c and they will grow fastest in temperatures between 22c and 26c I aim for 24/25c light's on and 22c lights off. Temperatures bellow 21c and above 29c slows the plants metabolism, thus slowing growth. There are many who grow at the extremes all the time and say 29c is fine or higher and although they get no problems, they are not seeing how good the plant would look when grown at the correct temperatures. Also temperature is connected to your light conditions. The more light available (watts per sq ft) the higher the ideal temperature for your plant gets. During the dark period, the temperature can be allowed to drop up to 5c without slowing growth but much more and the plants can suffer slowed growth and stretching. Plants kept at a more consistent temperature are likely to grow better, sturdier and denser. Root temperature is just as important as the canopy and should be slightly cooler. Heat water/feed to a temperature that is around the pot temperature to avoid cooling the medium and shocking the plants. Ther hotter the air, the cooler the water can be.
