need help with lightning..

So i now have about 15 different strains growing. its been 2 weeks in the seedling stage and plan on switching them to stronger lighting systems.

i first decided to go hps for veg and flower but recently read some journals on people who tryd hps all the way and who tryd mh for veg and hps for flowering and they said that their harvest was better.. but some growers said that both harvest came out the same.... as a first time grower i dont know what to go with and time is running out.. any suggestions,?? also i decided to go with 3 600watt because i can put them closer to my plants as opposed to 2 1000watt. i have a 7x7x7 grow room... i will also have cfl 6400 hanging during veg phase and then will switch to 2700k bulbs during flowering.. i will have those hanging so they can assist the lower part of the plant with additional lighting. but im still stuck on my original thought.. HPS ALL THE WAY OR MH+HPS??

any advice, suggestions are noted and appriciated.. thanks fellow growers!

money is not a problem and plan on getting the best bulbs out there!!

MH is better for veg since is has a blue color spectrum. It will keeps the inter-node length shorter and wont stretch as much as HPS. Either way full HPS will work fine but is more for flowering.

IF you need lightning, go fly a kite during an electrical storm. Tie some of your house keys to the kite to attract the lightning you are looking for.

The Haze is right. Studies show that MH is better for the Veg stage and HPS for flower. If you don't want to by conversion bulbs or ballasts that will run both then HPS is fine for both.

what do you use?

You can get Digital ballast that will run both. All though not suggested a HPS ballast will run a MH bulb. MH ballast will NOT run a HPS bulb.
