If you want to increase female ratio's , keep temps in the lower range, have a higher N to P and K ratio, use a blue spectrum for vegging.
Wrong. A female.. or a male... is already predetermined by seed.
A hermie = a plant that is stressed which triggered "emergency" mode and it makes male and female parts so it can release its offspring before death.
When a plant realizes its going to die soo due to enviornment change... it goes hermie.
Where ever you read this 1 hour light bs... its BS...
Just put it this way... when your sleeping imagine some giant fuck turns the lights on for like 1 hour... and then turns em back off... wont u feel stressed out?
same with a plant. and almost most organisms... STRESS KILLS.
