get two light systems
 

hi,i have a choice to get two light systems im not sure which is the best for growing, the stuff. the choice is between a 400w MH and 400w HPS. THE OTHER CHOICE IS, 2,400w HPS LIGHTS. my grow room is 6' x 5' x 7' also should i spend the extra money for the agro bulbs?. the type of system i was looking at was the diamond lumenarc lll. dose anyone have any experience with these lights. will anyone recommend a lighting system. thank you.

It is better to use both MH and HPS to give your plants the full spectrum of light. If you can afford it then buy the best bulbs you can because they usually last longer and put out more lumens.
