Review: The £20 Plastic Walk-in Greenhouse


These get slated regularly on garden forums, but I'm terribly fond of mine as I wouldn't be able to plonk a proper metal/glass greenhouse in our rented garden. It needs to be looked at as more of a disposable greenhouse, though - don't expect it to survive longer than a year. I opted for a 3' x 6' walk-in one: it has oodles of shelving, plus space up the back wall to grow a decent amount of cucumbers.

Pros:
  • The shelving is brilliant.
  • It's really cheap, and easy enough to assemble.
  • It's meant that I've been able to grow a decent crop of tomatoes and cucumbers this year, plus plenty of summer ornamentals from seed.
  • Daytime temperatures are reliably 5/10 degrees warmer than outside.

Cons:
  • It needs tying to something fixed. Really really. The guy-ropes aren't good enough, and weighting it down with pots won't work. Trust me: you really don't want to be found weeping into a pile of broken greenhouse and dead plants.
  • The plastic will disintegrate, so you'll find new air-vents occasionally.
  • The zip will inevitably break after a few months.
  • It doesn't keep frosts out, even with the door zipped up. Also, temperatures can soar to over 40 degrees in summer.

  1. Do they do mini ones for balconies I wonder? It would be ideal.

    Found you through Blotanical. I hope you enjoy it there and we'll see you around a lot.

  2. Hi Melanie, thanks for the helpful review. I'm tempted by this greenhouse, to try and keep blight off the tomatoes next year but where did you find one for £20? All the walk-in plastic ones I have seen are £40-£50. I'll second Sue's welcome to blotanicals, it's a great place to meet gardeners from all over the world.

    Hi Sue they do these plastic greenhouses in all sizes, even pop up ones to fit over a grow bag. There's bound to be one that would fit yur balcony.

  3. It was from B&M Home Bargains - they've taken over a lot of the old Woolworths shops. I'll edit the post in a minute.. :)
