Sorry, advance warning, bit of a rant coming up, but I don't often rant.
Last night on GW on TV Monty said that one indispensable piece of kit he has is his warm bed with heated cables in it. He said it cost £700 years ago and has saved him 10s of thousands of £s. Then he said if you can't afford that he had something cheaper, a big heated pad to put under seed trays. That cost £100. I don't see the average gardener affording that sort of thing, you need a huge GH to put it all in for a start. I think GW should be more for the average gardener.
Or are we all interested to see that anyway? How I miss Geoff Hamilton and all the things he showed us how to make cheaply.
