[Ag-eq] Jewel's greenhouse

[Jewel]

Tracy!  Southland has had a remarkable winter if one can give it that label.  Apart from a couple of 
hard frosts, it has been no less than spring.
I don't know how cold it would get in the greenhouse if we did have a really coldday, but it is not 
cold, per se, which damages plants, it is getting frosted when the cells freeze and then burst when 
the liquid that they contain expands and bursts the cell wall.

Hi Jewel.
The plants don't get too much cold air?  How cold is it there in August?
I don't think cabbage and cauliflower need pollinators, because you're not
looking for seeds.  But I think it's safe to uncover plants you do want
pollinated when they start to flower.  I wonder if cauliflower needs it to
start being warm before it starts to flower?

Tracy!  When I had the original greenhouse assembled, it was, entirely
covered with plastic sheeting, which meant, unless I kept the front flap
raised, there was no ventilation, so I cut the plastic away from the top and
replaced it with frost cloth,thus  creating a continuous upward current of
air;  as the rising hot air escaped from the top, cooler air was sucked up
from lower down.
I have had plants, either cabbages or cauliflowers, or perhaps both, in
there since the beginning of August, or was it July, and they look very
healthy, but there is no sign of them growing cabbage drumheads or
cauliflowers.  They are protected from the unwelcome attentions of cabbage
white butterflies and other such pesky insects, but do polinators have to
have access to them?

Jewel, how did your greenhouse invention work out?  What was the fabric you
covered it with, again?  I've forgotten.
