Now I am looking they all seem to be "dual spectrum". originally I was going to purchase the following:-
2 x digital ballasts
2 x 600w BLUE spectrum MH bulbs
2 x 600w RED spectrum HPS bulbs
And obviously switch the bulbs around from veg/flower.
My question is - if I go for 2 x digital balasts with 2 x dual spectrum HPS bulbs will this be detrimental to the plants (will the yield be effected? - I want a big yield so I only have to grow twice a year and be self sufficient) - as in both stages of veg/flower they are getting both spectrums of light - whereas the olds style bulbs it's totally customised around what stages the plants are at.
Cheers guys
