Im new to this and getting ready to germinate my White Widow seeds, can someone let me know how much light they will need at first and when i should switch them to the 600 watt HPS Thank You....I have 2-75 Watt floros that I was thinking about using at first? My Cabinet is 5'6'' tall 6' wide 2'6" deep...2' width of my grow is for clones, so I have aprox 4' wide area for mature plants...I will post picks of my grow cabinet when I get the lights, fan and ducting installed...
