I have a nice set up in my walk-in closet with a 400w MH + HPS conversion. I have good ventilation and air circulation. I just germinated 3 Femnized PPP seeds from Nirvana and placed them into FoxFarm Ocean Forest soil with added perlite and limestone. 2 seeds where planted 2 days ago and the other was planted yesterday. How long should it take on average untill my seeds break through the soil and what about lighting at this point? Do I turn the light onto 18/6 as I would for veg or do I wait till the seeds break through the soil before I turn the light on?
