We have ordered 2 cool tubes for the hps to help reduce heat and a new 6 inch inline fan for the lights alone. Also will most likely take out the MarsHydro II and it will go in a 4x4 to flower . We will then add in 8 x 300w MarsHydro LEDs , one for each plant , while still running the 2 hps . Should look cool and produce some good medicine with just over 2000 watts of flowering, just 2000 , because the hps will be turned down to 600w each with just over a 1000w of LEDs , for a total of 2200w. If heat is not an issue I will leave the 1200w MarsHydro in place and our 4x4 will be for there new light next month.
