Interesting, but I believe that PET is not particularly stable under UV
light. It would probably not be too long before the greenhouse
disintegrated.

The rotary bird scarers I made out of such bottles lasted 3 years before
falling apart. This is interesting, and gives the kids something to do, but
it's only delaying the inevitable. In fact it can be argued that it's an
environmental disbenefit rather than benefit, since the bottles used in this
way can no longer be recycled, or so I'm told.

I line my GH with plastic bubble wrap, and that lasts several years before
disintegrating. I'd imagine the bottles would last longer, being thicker....

Bubble wrap is polythene. Bottles are Polyethylene Terephthalate.
Completely different things, despite the somewhat similar names.

Polythene = polyethylene. So how different? - can you point me to an
url with the chemical structure of both?

(Not doubting you, just curious).

Polythene (polyethylene) is an addition polymer of ethylene i.e. (C2H4)n

PET (polyethylene terephthalate) is a condensation copolymer of
terephthalic acid and ethylene glycol, i.e. (COO.C6H6.COO.C2H4)n

Yorkshire water is chlorinated Dutch tap water isn't. Yorkshire tap water
isn't
filtered water extracted from the Rhine.

The water here is so chlorinated that we have a filter on the kitchen water
tap and take bottled water to the bedrooms.

The tap water here is drinkable most of the time.
Occasionally it is over chlorinated - very noticeable after
a sip of tea which tastes metallic. It also goes brown
sometimes for a day or two for reasons unknown - possibly
someone working on the mains. We keep some bottles of
spring water for such occasions.

Our milkman brings us bottles of water three times a week, only because the
taste of chlorine is unacceptable to us. I insist that the kettle is
filled only from the filter tap and I know, always, if someone hasn't done
that.
