First hydro grow journal (NL/Haze, White Widow, Silver Haze, Himalaya Gold)

Hey this is my first indoor hydro grow and im going to take and post pics from seedling to spliff. I'm using a 2m*1.2m*1.2m tent with 600w hps light with 6" carbon filter and growing in 60%cocoa 40%clay pebbles in a flood and drain recirculating (homemade) system. I'm also vegging under a 5.5foot double fluo light to save money instead of vegging with hps, i will be using the hps light during last week before change over to 12/12. I will be posting the first pics of setup in next few days and hopefully some of my ladys will have germinated and you'll see them aswell. Untill then any questions or any advise will be appreciated and get a reply. Thanks from buddha
