I received a small 3 tier polythene greenhouse for xmas and want to use
to grow some seeds of which I have many this year.

I put it up and check the temp in it and it was only around 7c at
approx 4 pm in the afternoon.

If I put seeds into unheated propogators with this greenhouse will this
be sufficient for them to grow or will it be too cold at the moment ?

I was trying to get some sweet pea seeds going before it's too late and
the apparently only need around 10c - 15c

I was also going to grow geraniums in a heated propogator which I can
plug in and leave in the green house as it has an electric point right
next to it.

or should I look at some sort of heating for the greenhouse but given
that it is small and polythene what would be suitable to heat it with.

I am trying to keep the seeds outside in the new greenhouse to protect
them from my wife and children who don't give them as much regard as I
do !!!

suggestions please or do I just need to wait until it's warmer to use
these greenhouse ?

A tube heater? Usually 60W or 100W. Such as this......

so it would just be the cost of a light turned on 24-7? How much does
that equate to I wonder?

Obviously it depends on your energy supplier and wattage,, but around £1.20
a month for 'a light bulb'. Info courtesy of Google.

I wonder if you could use the low energy bulbs making that around what,
say 50p a month. I have a Halls greenhouse, I think its about 8 x 8.
My new paraffin heater blew up and I don't want another. Would 2 x low
energy, 100 watt bulbs be adequate to heat the greenhouse so that I
could use it now?

No, the electricity is 'used' to create light. The tubes I spoke of use all
the electricity to produce heat. Do you remember the old style portable
heaters that used a long coil of wire that glowed red?....similar concept,
but safely enclosed.

No, because low energy light bulbs do not use the number of watts which are
shown on the case, that is a guide to the relative light output, the power
consumpton is much lower, about 20 watts for a light output of 100 watts.

In the case you mention, the heat output of two bulbs would be only 40
watts.

And, the cost of a light bulb, would be considerably cheaper than a heater,
and would do exactly the same job!
