1st time indoor grower light question
    #234659 - 05/31/09 05:56 PM (7 years, 4 months ago)

This my first time growing indoors from some bagseed.  I grew 7 plants out and only kept the strongest female.  It is now growing in soil under 5 x 23 Watt 2700K CFLs.  It is in early flowering (12/12 for 2 weeks).  I want to ditch the CFLs and flower it under a 150 watt HPS.  Can I just buy a 150 Watt bulb and screw it into a socket that I have a CFL in?  Do I need a ballast?  I have fans that I can use for ventilation so heat will not be a problem.  Sorry if this question sounds silly but I'm new to this.  Thanks for reading.

When using HPS or MH you have to have a ballast. I seriously doubt that HID bulbs will fit in CFL sockets, but I'm not about to try. Anyhow, yes. Gotta have a ballast.
