With plenty of seedling growing in the potting shed, and hundreds thousands of salad leaf seeds to sow, I was determined to get the salvaged bubble-wrap pinned to the inside of the greenhouse. I used drawing pins – easy to remove and minimal damage to the wood.
The bubble-wrap originally protected the polycarbonate sheets while in transit.
Bubble wrap can’t be recycled or burned so it would have ended up in landfill. As it is estimated that it takes 500+ years to decompose, that is not something I’m comfortable doing until I have re-used and re-purposed it many, many times.

Additional Heating
I’ve been looking at possible ways to warm the greenhouse – and protect my salad leaves – when the temperature hits zero or below. Preferably at low or no cost.
There is power point nearby for electic heaters and I have bad memories of smelly, smoky parafin heaters.
I found information on the internet about using candles to heat nested terracotta pots; the idea being that instead of the heat from the candle rising up, the pots (linked with a steel bolt suspended on nuts and washers) will warm up and – similar to storage heaters – will retain and then release heat.
The cheapest version is a Cornish Heater.
Do they work? Some say they do (for a small space), others say not.
And you should never leave lit candles unattended.
I’ll stick with garden fleece, and maybe tuck them up with a hot-water bottle or two on the coldest nights.
