hell yeah...alot better, hps is what your suppose to be using...and its more watts than the 125 cfl combined both 75s, plus you get better light coverage becas its 2 lights.

trust me bro, if this is your first grow, dont get any sativa strain...get a strain that is really easy to grow and flowers fast and will still be dank as hell, there are fast flowering strains that have a sativa high but dont grow like them. and make sure about the stretch, even though there hps 75 w doesnt have alot of penetration, so you need to keep them short, best bend over.. LST

but with 150 hps you should yield at least around an ounce for your first grow...when you get better around 2 ounces...the most you could get from that wattage is a little over 4 ounces, and thats with a good yielding strain and having alot of expierence with that strain.

anyways yes its better, but there will be more heat, so make sure you have proper ventilation and keep temps around 75..dont go over 85 (w/o co2) humidity around 50%, dont let it go alot over that, the last thing you want before harvest is mold, espically watch it the last 2 weeks of flower, try and keep it around 40-45%. If all that is in check, you start with good genetics, dont mess up on the nutes you should have a nice harvest
