About Grow Under Glass

Grow Under Glass is a practical resource for anyone in the UK who wants to get more from their garden, allotment, or patio by growing under cover. No overblown promises — just straightforward, honest guides covering the things beginners actually need to know.

The guides here focus on UK contexts, UK suppliers, and UK weather. Most content online is written for a US or Mediterranean audience, which causes real problems when you are trying to follow advice that does not apply to British conditions. That is the gap these guides are written to fill.

Topics covered include:

  • Cold frames — choosing, building, positioning, and getting the most from them year-round
  • Seasonal growing — what to sow and when, tailored to the UK climate
  • Troubleshooting — damping off, overheating, pests, and the other problems that catch beginners out
  • Buying guides — honest comparisons of materials, brands, and what is worth the money
  • UK-specific guidance — frost dates, hardiness zones, and suppliers that actually deliver here

About Tom

I am Tom, a UK gardener who has been growing under cover for the best part of a decade. I started with a homemade cold frame built from an old window and a few bricks, and gradually moved on to greenhouses and polytunnels as the obsession took hold.

I have made every mistake going — seedlings fried because I forgot to vent on a sunny March day, lettuce bolted in an unshaded frame in July, a whole tray of brassicas wiped out by damping off because the compost was too wet. I write these guides so you do not have to repeat them.

All guides are written from firsthand experience or thoroughly researched from authoritative UK sources. If I have not tried something in British conditions, I will tell you. If there is a catch you will not read about in the glossy catalogues, I will mention it.
