I just bought a 400w hps light to add to my room .i have 4 150hps inthere already my question is can I just addtotal watts and that is what I am lighting my room with 4x150+400=1000w hps total?
so its 1000w but the intensity isnt a 1000w. I put the 400 in the middle and I placed the 150s in the areas not as bright. kind of a secondary light. I wish I knew how to post pictures because i have been pretty impressed at my growth and budding so far. this is my second grow fromclones I had of some bag seed. the best bagged seed I ever smoked. believe it or not it was better because I grew it....LOL or I justtook better care
my area is 6x4 8 feet tall it is airconditioned in thebasement never gets over 75. it has fresh air intake and is vented outside the room. I use two 12 inch ocial laying fans for air movement with inthe room
