Hey thanks Khyber, back to work today . I've already taked the 150w hps but maybe i can add some holes in the System so i can plant the babies more closer from each other, or maybe i can add 2 neon 36w-6400k from the bottom (for the veg?). I was thinking of planting 2 lowrider Maxi GOM or 2 Automazar from Dutch Passion bank, they should be a little smaller than a normal plant then maybe i can go with the hps alone (distance 25cm?). What do you think? As for the irrigation im really in trouble because i really dont know where to start, The Sistem arrived without any instruction and im a total noob with hydroponic sistem ( some years of exp in soil) , if someone can help me, without hurry obviously, i would be very grateful. And sorry for my eng, lol. a hug :jointsmile:
