i think instead of the 'what types of food attracts mould' i'll change it to 'what types of fruit attracts mould the best' because there's like tonnes of types of food and within each type of food there another ten thousand type of food and i'll have to get more than 1 for each type of food so it'll probably be a bit to complicated and the results might not be exact...
so i searched the types of fruit and it came up with
Pome, Citrus, Stonefruit, Tropical, Berries, Melons, Tomatoes and avocados so i'll probably get a few fruits from each type and do it~
