Purple Kush Lighting

[Super Duper]

Hello guys! This is my first post here, please do correct me if I posted in the wrong section. So, I have a purple kush which is about 1.5 months old and I was wondering how long should the plant be lighted? does the lamp's color matter? (white light, yellow light)?

Cheers and Thanks!​

1.5months...did your plants show the sign of gender already?If it shows gender already you can change the light12/12,during flowering,your plants need both red and blue lights.
