FAQ :: Growing :: Lighting and Photoperiod for Indoor Growing
For Papaver Somniferum varieties, it is best to use HID lamps (HPS or MH). A 1000W can shed ample light to grow a 12ft by 12ft area. HIDs get hot so you may need to cool the room or find a plant that grows in a warm climate.
Photoperiod for germination and the vegitative "cabbage stage" should be 12/12 (12 hours on; 12 hours off).
To force flowering use an 18/6 or 24/0 photoperiod.
