temperature

hi got my new greenhouse well a friend gave me it its a glass alluminium one.
what temperature should it be when its sunny like today here in lincs its been not too bad ive got a thermometer which ive got in the kitchen put it in the green house and it said 110
how accurate that was i dont know the thermometer was in the sun.

 

Hiya hammer, it is worth investing in a max-min thermometer which has markers to stay at the high point and low point of the temperatures reached during a period of 24 hours for example, it will give you an idea of how much of a variation your plants are getting. It's the rapid variations that cause problems with plants and if the sun is shining temperatures of over 100 can be reached very quickly, if you are not around during the day, an automatic window opener is a must and probably more than one vent which is how most greenhouses are supplied. Shading also helps, the cheapest option being the paint on type, a little bit of investment now will help you get the best out of your greenhouse. Good luck with it.

 

Hammer. You don't give your location in your profile. But you have said in your post that you are in Lincs so you are similar to me, Yes. My greenhouse was at 100+ old money today Great. My cannas are poking through. Digger is quite right but I don't want to get into a debate about painting and bubble wrap again Bit sick of it. If you have a Wilko's near you a min-max thermometer is only about £4 by the way.
