I have 2-150 HPS lights but, I have them on hydro, these are ina pot in a green house I was just looking as if I put them inside noe changed the lighting cycle, if they would bloom early, but now EEHHH forget this growing stuff is too confusing, I have left it all up to my hubby, and I am gonna stick with my lawn. Im gonna let the two I have take thier sweet ass time and do what ever they do, I don't give then nutrients, just water and lol gatorade, orange to be exact. and they love it and are doing very well, so why fix it if it aint broke right??
