Okay I think I can work with that info and decipher what to do. Thanks bro.

Yields are based on energy consumption. So 400w HPS will yield more if all other factors are ignored.
Now reality is, your t5 could potentially have a larger light foot print...which may fit more plants under it.
HPS can penetrate much further than cfl... so if you have less plants that are taller, HPS would be a better option.
Lots of variables to consider here, your individual set up has a lot to do with these factors.

Okay so I’m just trying to figure out, will I get better yeilds with 192w HO t5 or 400w hps @ 75%?? I know that dimming the ballast diminishes spectrum and degrades the bulb quicker but I’m not really worried about my bulb life span. I just want to know if I’m missing out on a little better yeild using the t5 instead of the hps @ 75%? Also my plants are not scrog which I know is best for t5. Just 4 topped and lst’d Autos. Tia
