Need help picking a MH Bulb

Thread starter #1
I am trying to pick a MH bulb. It's my first grow so I did not want to spend a lot of money.
I have decided to go with a Plantmax bulb, but they have 3 models
3000k 68000 lumen
7000k 56000 lumen
2000k 96000 lumen
It's for my Veg phase. Please help me as i have no idea what the difference of these bulbs
