It was quite easy to put up,as we marked the pieces as we dismantled them,so we knew what went where.I was lucky getting hold of it,my dad & I had been watching the newspaper ads for months,but any for sale were snapped up very fast.Then I heard that a nursery down the road was selling up & went to see the owner for a chat-result!
At the minute,I'm growing tomatoes,chillies,strawberries,tomatillos,peppers,courgettes,squashes,cucumbers,pumpkins,beans,potat oes & sweet corn.It has been a bit of a rushed job this year,as we only got the cover on in May,rather late.Next year I plant to build proper beds & get a fig & nectaerine in there too.
It is great-I had crops way before I normally would,apparently Dec & Jan are the only 2 months that you can't grow much,beause of the light levels,but you can extend the growing season no end.Yesterday I planted salad,carrots,beans & wallflowers.I sell a lot of my produce too,as there is more than enough to spare.That helps pay for next years seed.
A good book to give you a better idea,is 'Growing under plastic',by Bernard Salt.He covers polytunnels & greenhouse,with what you can grow when.As for finding one,perhaps 'Farmer & Grower' or one of the horticultural magazines might be worth a try,or asking at your local garden centre if they will be getting rid of any in the near future.
Good luck-if you need any nmore help,let me know.
