Ive never ever had a kit brew suffer light strike when brewing. Firstly I think the plastic of the fv is sufficent to prevent it. When I brew (which hasnt been for 2 months due to moving house) I do it in the kitchen which sees daylight all day (ofc, not gunna be at night is it) and then the power of a light bulb when its dark
There was a thread regarding this but i think its in the off topic bit. search "Skunking" because thats a term used to describe it.
It was awhile ago when I read it an im sure I remember someone saying its something you only really get from AG brewing, something to do with the hops....
ok i had to go away there an find the thread
