Lighting; cfl with HPS

A question from a fellow grower:

So I have a question I have two seedlings going and I am planning on getting a 150 watt hps grow light next week but this being my very first full term grow I am wondering if I need the hps on top of CFL bulbs?

Not really, keep the cfl for your seedlings, but you will need a new light for vegg and …flower.
Here is a link
Now this one would be for flower.
The one you want now is the 400 watt…if you go there just switch the 600 to 400. You can always order the 600 for flower


Look! good - use the cfl’s for your “sidelighting” and increase your yields by at least 40%, you are right they work well for gremination/seedlings
