Hi all
New here and new to 'growing my own' veggies.
Had some success with my first attempts at growing potatoes and peas and have been severely bitten by the 'homegrown' bug.

I am now considering getting a greenhouse to expand my veg choices and allow for a longer growing season. After trawling through the pages and pages of info on the web about greenhouses, I am even more confused then when I started!

Can someone please enlighten me on a few points?

1 Which is best - horticultural glass, toughened glass or polycarbonate panels?

2 Is it necessary to have a base fitted to the bottom of the 'house'?

3 Can automatically opening vents be fitted to replace manual opening ones without too much alteration?

4 Is it good practice to line the house with insulation such as bubble wrap?


Any help would be very much appreciated.
