It meets the spectrum perfectly, but it may not be enough light depending on how much you will be growing...

Could get 2 x 125w CF bulbs - one high colour temperature (blue-white), one low colour temp (red-orange).

A 250w HPS is fine for flowering, not ideal for growing, unless you can get a SON-T-AGRO bulb (not the same thing as SON-T-PLUS 'Greenpower')

Is there a savings over the Son Agro?

I don't see much of a difference - sounds like the same bulb in a different package.  Are the lumen outputs the same?

SON-T-Plus Pia (GreenPower) 400w - 55,000 lumen - low colour temp light (red/orange, for flowering)

SON-T-AGRO 400w - 52,000 lumen, mostly low colour temp, with added high colour-temp light (blue/white, for growing).

If only flowering, normal SON-T may be better for slightly higher light output.

If using one light to grow and flower, AGRO is better, and 3k fewer lumens is a small price to pay for more complete spectrum.

Some growers prefer to flower with AGRO, as some sources say mixed-spectrum light is better for flowering.

Overall difference between flowering with 400w SON-T vs 400w SON-T AGRO - not a lot.

HPS might be the most efficient, but what is the quality of a (Warm)  MH bulb, such as the SunMaster Warm Deluxe, or AgroSun Gold in terms of the spectrum, not lumens?

I imagine that because it is mostly blue, with added red, it would be a the opposite|equivalent of a SON-T-AGRO...
