Outdoor Greenhouse Temps!

[Think]

Hello I am growing some Think Different in a cold frame greenhouse there only seedlings atm but the temp in the day is reaching 30 degrees C (reading on a glass thermometer) is that too hot? I will be getting a digital Thermometer/humidity reader this week that would probably be more accurate! if anyone can help me I would appreciate it

is there a constant air flow in your cold frame? if not, make some holes at the bottom and open the frame when you know it will not rain.

Well today it was hot so I opened it up and managed to lower it to 30 C I have made some holes they're not that big but I have made a few! I leave the bottom open a little when it isn't to hot. I'm looking at battery fans on E-bay would you think that would be okay to cool it down and to circulate air around the plants ?
