When to switch to 12/12

This is my first indoor grow using photo period seeds .I germed a Wembley and Exile from attitude June 29th.they are in a grow hut with 1 400w light .When do I go 12/12? Ive always done autoflower.

Depends on how big you want your plant, people say around 16-20 inchs, but depends on your grow area also

everyone has their own opinion but most wait until you see preflowers...depends on space

you can put em on 12/12 when u want.
cheers

frigin auto flower is screwin with nature, wait for pre-flowers or nuts.
