Some equateorial sativa's require 13 hour of darkness to flower, but most strains will need 12 minimum, so add darkness instead of losing it.
pirate Reviewed by pirate on . exact 12/12 ? does it have to be exact 12/12 for flowering ? or can it be 1 hour to the right or to the left ? because the 12/12 doesn't really fit my schedule and I can't switch it at the exact time. Rating: 5
