Well this is my first personal grow, I invested in a 20 site Aeroponics with a 1000 watt MH/HPS conversion lighting system. Charcoil filter vent system and osciallating fan. Started to germinate 3 days ago, deeds cracked so I transplanted to RockWool medium in 10 gallon aquarium in dark covered with plastic. One has already sprouted so I moved it to system on 18/6 intervals for lighting. Lights are 24 - 36 inches away is that ok? And When should I start nutrients, I only have it with distilled water at moment as not to shock the seedling. And any other observations or comments please feel free to express. Anything can help guys and gals. Texas Style
