		CFL bulbs 
		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.
