We saw some greenhouses advertised at market last week, and since we’ve just sold Quinta das Limpas we can afford a ready-made one. A 12m2 aluminium framed greenhouse with glass sides and polycarbonate roof, with double doors, 3 windows, gutters for rainwater harvesting, delivery and installation, will cost around 2,000 euros. That’s a LOT of money!
I don’t know where to get a ready made polytunnel in Portugal, or how much they cost (anyone?). So the other option is a home-made polytunnel using either bent plastic pipes or bent mimosa/eucalyptus sourced from our land. This is certainly the cheaper option and, at first thought, the greener option.
But is it? How long will the polytunnel last compared to the greenhouse? How often will the plastic need replacing, and how easily available/expensive will the plastic be in the future? How do we dispose of old/torn plastic? Do I want to spend time every year patching/rebuilding a home-made polytunnel? I think a greenhouse would be a lot easier to clean – should that be a big consideration? And of course, which is better for growing in – greenhouse or polytunnel?
Hmmm … I really don’t know. Which is why I’m posting this here, in the hope that anyone reading this will leave a comment with your thoughts (please)!
