I have three thermometer's in there too..
One in the front of the
greenhouse, one
in the back and one inside one of the little
greenhouse's....
That way, I can watch for hot spots..
They are aloooooooooot of work when you are just starting out with them, you must watch the weather and sun and project and aweful lot...
Example..
in the
spring, you need all the hot warm air you can get, so you don't open the door alot....
you want to keep it in...
but come the days when they start warming up a bit during the day, you then have to vent a wee~bit so it doesn't get so hot, but you then have to watch the clouds, and if it starts to get cloudy, you have to start closing it up early
to keep the heat in for over night..
It becomes a science, and once you get the ball park idea, it's not too bad, it's just the first time learning....
If you get heaters, fans, etc.. then it's altogether a different formula..
I have to watch my zippered ones, during the day,
and zip them up when the sun goes down to keep the heat in..
I am looking to be able to start my annuals first, earlier than I do.. cause it's always perfect timing when I start my veggies, they sprout, harden them off, and it's just about transplanting time.. but then I have the time
for the annuals, but by the time they
flower and
half the summer is over, I have to switch and start the annuals first and then do the veggies,
but weather doesn't permit it up here..
Hence that's why I"m looking into a small cheap heater for over nights..
