Greenhouse Growing Log
Turn a greenhouse from a place things happen into a place with a record, so a bad germination or a lost crop can be traced back to the week it went wrong.

What this sheet is for
Keep track of what is under cover at any moment and how it has been treated, so a crop that sulks can be read against the conditions it actually had.
Who it is for
Anyone growing under glass or plastic at home or on an allotment, and people sharing a tunnel where more than one person waters.
How to use it
- Fill in the house or tunnel and the season once at the top.
- Add a line for each crop or batch as it is sown, and date the potting on and planting out as they happen.
- Use the lower table for the days you take a reading or do something worth noting.
- Leave the temperature columns blank on days nothing was read — a gap is more honest than a guess.
What is on the sheet
One page, top to bottom:
Printed under the title: What is under cover and how it is being looked after — crop by crop from sowing to planting out, with a running record of watering, venting and the temperatures you read off your own thermometer.
Your readings, your conditions. No temperatures or watering frequencies are printed here. A tunnel in one garden behaves nothing like a glasshouse in another, so the readings are the ones your own thermometer gives and the watering is what the plants in front of you need.

Questions
Why are there no target temperatures printed on it?
Because they would be wrong for most readers. Glass, plastic, aspect, ventilation and crop all change what a sensible reading looks like, so the columns take the figures your own thermometer gives and leave the judgement with you.
How is this different from a growing log?
A growing log follows the plants. This follows the structure they are in: what is standing in it, and how it was vented, watered and fed.
