CFL bulbs

[MistaJ]

Hey guys,

I've done a bit of searching but am unable to answer my question.

I currently have a 400W Sonlight HPS Agro bulb with ballast. I was wondering if I would be able to put a 250W CFL in there instead for my veg period.

I am aware that the Agro bulbs give off a bit of blue light for growth, but it's mainly to manage the temps and I don't want to blast seedlings with the HPS.

Thanks.

CFL bulbs have their own ballasts, built-in. I wouldn't screw it into a 400 watt HID ballast fixture.

Ah ok, thanks for the heads up man.

I shall look at getting a alternate fixture for one.

Cheers.
