i got a HPS250. and I am using 'passive hydroponics' I got a 10 gal bucket with the solution of miracle grow, urine, epsom salts and Oxygen Plus. My plants are a mere 6 inches and they are going through alittle trouble right now, But nothing a couple of good people can't help me fix. The strain I am not sure. My friend brought me some weed from the Gastonia Cancer institute. And these seeds are what I am using. The weed itself, the bag I bought, smelt like it had been vapourized (I love my vapourizer) Its pretty kick ass shit form some funky smelling weed
