I'm doing 18 on, 6 off, now I'm wondering when I switch to my hps and 12/12 should I keep the same time, like my lights are on during the day and sleep at night, but I kinda wish I would of did it the other way around since it seems to be cooler at night which would help cool down the lighting.
So say if I start my 12/12 tomorrow, I'm currently going on at 10am, so at 10am do I put my hps and 12 hours on, then 12 off after that, does it matter when you change it if its during sleeping or when the light is on?
