That looks very effective
Thx!
I assume you are going for corn of the maize / sweet corn variety, rather than corn / wheat?
Indeed:
(Wikipedia)
"Corn most often refers to maize, the yellow, large-grained crop native to the Americas.
It can also refer to the main cereal crop of a country or region:
Wheat, barley and oats in England and Wales
Oats in Scotland and Ireland"
For wheat/barley/oats I use coconut fibre mats.
