Hi all,

I'm a 'non' gardener, but I like the results there of so ...

The lean-to greenhouse has no opening windows - no not an easy
option to put some in (without a full re-build - not my design
etc. etc.) so can I use on of those window openers to open the
door or does anyone have any other ideas?

I'd thought about a PV-cell (or several) and a few 12V computer
case fans but ...

TIA

Nick

Put louvre style vents in by taking single sheets of glass out, so
long
as your glass is standard they should fit and you can get automatic
openers for them.

Not a feasible option as it is 'clad' is plastic sheeting - thought
about
that! Only when (if) I have to rebuild it will that be an option as
nothing is standard anywhere

Putting auto openers on the doors will not work as you would only
be able to go in when it was hot!

Ah! good point did not think about that!

It would depend how you mounted the opener. Let's say the door opens
by moving to the right. You set the opener on the left and arrange for
it to
push against a bracket on the door, without being fixed to the door.
Then if
you want to go in you can move the door manually. Arranging sufficient
travel for the door might be difficult if using a normal vent opener,
but not beyond the wit of a competent DIYer

If its not attached it will open the door but not close it! --

True, but a weight on a piece of string will do that.

Many thanks to all, however there is one bit of grit in the Vaseline of
life, the door is not sliding! and I think a bit more sitting looking at
(with a beer/coffee) is needed to get a result.

Much to ponder on

Thanks again all good to have a second brain occasionally!
