The 4000K light is many times cheaper than any 6500k bulb....(like $20 for a 4000K and $70 for a 6500K.)

The 6500K has more "blue" spectrum.
I want max veg growth.

If on 12 plants grown fat (big) if the 6500K bulb will make a difference in size then I would go with two 6500K bulbs

I already have the bloom bulbs sorted.

thanks in advance

A 4k will work just fine.

There are people that veg and flower with just an HPS. You can do it with a metal halide light too.

That's awesome, the 4000K 1000W bulbs, UV protected are so cheap, and they have a long life span too. Thanks :wave:
