6th week of flowering AUTOFLOWERS 20/4 I accidentally left 20w 600mn (very red) booster for 3h during dark period (I noticed as switched off) Will they hermy? To be honest my growbox has holes so it was never a total balckness.

autos don't care, you can grow them under 24/0 and they will still flower. its crule but you could do it. Might want to work on patching them holes if you plan on doing photoperiods.
