lights

is 6-8 full spec cf 30 w as one 400 w hps lights
and what are the pro and cons with full spec cf
and witch light sorce is better

 

-Compare lumens.

-Generally speaking, HPS has more penetrating power than any other growing light.

 

flourescents can work in some applications, but get real bro. and then get real lights. i persdonally prefer an HPS and a MH for flowering and a MH for vegging.

 

You don't need a MH.
Get a full-spectrum bulb for your HPS.

 

Go for the HPS first it will both veg & flower Metal Halide will only veg

 

I veg with flouro, flower with HPS. MH works for veg too.
