Well, the plan for the leaf collecting went out of the window, we have had that much rain i would have had a swamp on the back of my car after just the one trip.
On the plus side my initial findings with the thermal battery in the greenhouse looks promising.
For those that have not heard of thermal batteries – they are just a way to collect some of the warmth the sun provides and then releases it over night time. Basically a hot water bottle…A BIG hot water bottle.
I have used an old garden wheelie bin for my storage. Simply filled with water. It took about a week before any change was to be seen on the min/max temperature, Mainly the min temp has been the focus, as one cannot theorise as to how intense the sun has been, the time available, nor the temperature variation of the outside. But one has been able to do a simple test…
What was the minimum temperature inside the greenhouse when the outside froze.
Without the thermal bank it has dropped to 2degC, with a high of 26degc. With the thermal bank running for a week the max temp was reduced, as is expected because it partially goes to warming the water, down to around the 18-19degC. However, the Min temperature inside as the outside has froze did not drop any lower than 6degC.
This may not sound that brilliant, or that useful, and for the main part it is not. I am not likely to be growing tomatoes in it over winter. However I plan to grow winter salads, the varieties that grow outdoors over winter, indoors. My theory being that they should benefit from the extra warmth and protection, giving me a higher yield.
Well that the hypothesis anyhow…
Time will tell.
