What others have said about the Harvest-ometer:

“The Harvest-ometer has been a great tool for quantifying our data. We frequently use it when applying for funding.  It’s also a great tool to show our volunteers and local community just how much food we've produced. I like the fact that it also puts the statistics into a monetary and dinner form.” Emily Myers, Loughborough Farm

“We have found Capital Growth's Harvest-ometer of great use to weigh and record our produce. It gives plot holders the opportunity to see how much they have grown. Seeing the totals in term of finance and the number of meals gives an incentive... The lists of produce can even help to provide ideas for next season’s growing!” Tim Anderson, Maryon Park Community Garden

"The Harvest-ometer has been an excellent way of tracking our progress. Who'd have thought that what we thought would be a few courgettes and handfuls of beans would result in us recording over £70 of produce so far!  It's inspiring us to set higher targets for next year, and make sure everything that's edible is harvested!" Wayne Trevor, Norword Bzz Garage
