HPS AND MH for flowering pro's and con's plzzz..

ok so my questions are as follows
1 high pressure sodium- is it better for flowering or veg?
2 metal halide better with a hps during flower
reason for the above.. Thanks to the 12/12 from seed crew i am going to take my 2 small 4X4 rooms and make one big 4x8x8 room ..
i have 3-400 wtt mn ballast. what should i use for my flower tower????????????
i can get conversion bulbs to use either mh or hps..
WHAT COMBO SHOULD I USE FOR THE 12/12 LOVE MACHINE

High pressure sodiumis used for flowering and cabe used for keg the key has something to do with the way to measure wwitch is in kelvins. 400 w hps is aroun 2700 k
METAL halide is only for veg because it is abou 6900 kelvin.
i am not really sure of the definition bu i know HPS = FLOWER

MH = VEG

thanks i was going to get 2 more conversion bulbs and change them all out to a hps ..THANKS

I have heard that MH bulbs produce a more "sun-like" spectrum with more plant-active blues and reds than HPS does. However, MH bulbs, especially conversion bulbs for HPS ballasts, produce about half the lumens HPS does. They do put out less heat than HPS, so you can put them closer to plants and get more out of them. They also produce more UV radiation which the plants will respond to by producing more resin, as trichomes are a natural sunscreen for the plant. Plants flowered under MH will stretch much more than under HPS, and the buds will be substantially lighter. However, they will be coated with resin. The best of both worlds would be to combine HPS and MH during flowering.

If you add mh to your flower rooms as supplemental lighting to the hps, you will be very pleased with your results.

lol you peeps must have ESPN or somthing.. i am just getting one more conversion and put my mh in the middle and get a light rail so i can run the 8 ft length of my room with 3 400 wtt -2 hps and one mh.. got 22 of them going started 10 clones of white widow and 9 silver haze from seed all in 12/12 oh and 2 mothers that are used up. 1 citrol and one white widow.. need more room
