I'm wondering if anyone has any experience running 400w MH and 400w HPS side by side? I have a 400w hps and its great but my gf just got her 215 also and we're upping the op 12 total (in 3 gallon pots). I figure two hps would be fine but I'm thinking the extra spectrum coverage will give me better results (not that my results aren't good already). Any input would be great!! I'm excited to get this done.
