A single PL Light Systems ( no digital ballast! Todays light bulbs are far behind the capabilities of a digital ballast), 400 watt Hortilux Eye Super HPS. I germinate using towel method, into propagation cubes in dome until the tap root is about 1", under CFLs, when 1st leaves look good and strong trans into 3 gallon pots using Fox Farms Ocean Forest soil. CFLs on 18/6, no nutes for 2 weeks ( there's plenty in the soil). Then follow Fox Farms feeding schedule 1/4 strength first feeding! Ph 6.4 +-, IMPORTANT! Ph your water and nutes always! Follow the trichomes, clear, cloudy, amber. When you think it's done wait 5-7 days, you'll be glad you did! Have a good grow!
