I purchased the galaxy legacy digital ballast as well as a SunSystems 6" air-cool Blockbuster Hood. I plan on using a 400W metal halide for the vegetation stage and a 1000w HPS for the flowering stage, however I have the following questions:
Would it be better to use a 600 W for the vegetation stage? What would the difference be from using 400w?
Will a 1000watt HPS light be too much for a 2 x 4 x 6 tent? Will I get the same results with a more efficient 600W HPS light?
Any assistance is appreciated.
