Just wondering what would be more benificial for vegging my ladys , either a 400 Watt MH or a 600 Watt HPS ?? I know that they like MH for veg , just wondering if the other 200 Watts id be putting out , even though mostly the red spectrum ... would be better than the 400 W MH .


Thanks for any help

It's not just watts, it's wavelength....use the MH for veggin...hps for flower for best results...you can even add the hps to the MH for late flowering...supposedly it helps yields.

You can get enhanced blue spectrum HPS. How long you gonna veg? If it's a short time I'd go with the six hundred with an eye hortilux. This pic is two week old after transplanting clones with an eye hortilux hps. What more do you want?!
