Hi

I just wondered how long i should keep my brassiccas covered for? I have Kale, Calabrese and various cabbages covered with Enviromesh and just wondered if they should stay like this until they are harvested or can they be uncovered?

Should i also keep my taller brassiccas covered i.e. Brussels and Purple Sprouting Broc? If so how do people do this?

Thanks for your time
