I have a electric heater run through a thermostat controller & probe which
is very accurate,I have two of this set-up one for day & one for night,both
on timers so one set-up takes over from the other,it is automatically done.I
just have to initially set the parameters I want,the night is set to 59f/15c
and day has been at 71f/22c,but today was really sunny in the after noon so
the temp got in the 80`s.After input I have received off you guys I am going
to lower the day temp to 66f/19c?What do you think.I live in Robin Hood
country,that being Nottingham,England,UK.It can get quite cold here(zone
8)but really not that bad!My greenhouse is only a measly 10x8,but we all
have to start somewhere.

The heater is run with a thermostat so the heater will turn on any time
it gets colder.
I grow just about everything Intermediate.
Oh I have some heating cables for my Phals but I cant grow them too well?
What kind of heating system do you have in your g/h Keith?
It gets really cold in your neck of the woods right?

Hi Wendy,They only got natural light before,growing in the home,were
ever I could get them :-).what do you grow to that temp?So you don't
raise the temp in the day without the sun help?
Hi Keith, I grow in a g/h in S.Calif & have my heater set to go on
at 58 degrees. If there are plants that require a chill, they don't
get it & or don't grow/bloom. I grow cyms outside.
Were you growing indoors under lights before the G/h?

Am I worrying to much about trying to achieve the day/night temp
difference,do you find then that in greenhouse culture there isn't
prolonged temps that stay the same,i.e. 55f on cloudy days which
surely if continued at this temp will do the plants harm?I suppose
everyone's conditions are different so it is a case of trial and
error.I am only flapping because it is my first year in the
greenhouse and don't want to kill the plants.It will be a good
learning curve through the months to come!
Thanks for the advise,i grow intermediate,what are your conditions
for the advise given?

All we try to do is knock off the extremes -- misters to keep the
temp below 95F in summer, heat to 55F in winter. In between
these extremes, whatever the temp happens to be is what it is.
We raise it to 65 during the day and let solar gain take it from
there. Here in Co it is not unusual to have the roof vent raise
in Feb. because it has gotten to 80 in the afternoon. OF course
the next day it may be gray and not climb over 70. So I let the
excess heat out and hope enough stays to temper the heating bill.
