No doubt gpw is the standard baseline, and 1gpw is head of the class. I would assume most are at .5gpw
Having said that...
If your 1gpw takes you 63 days in flower and say 42 days in veg.
And my 1gpw takes 49 days in flower and say 28 days in veg....
Time is a huge factor in a commercial grow.
SQFT not as much.
Oh I get what you're saying, yeah, if you can improve/reduce your timeframe while maintaining a decent gpw, for sure. That's primarily genetics/strains, there are some tweaks you can do as a grower but genetics drives this the most I think. I'm assuming in my scenario running shorter flowering strains and 8 week veg to hit around 4 zips per plant. What I've found out recently after switching to CMH for flowering, but maintaining LED's for veg is there's something going on, possibly the change or mix of different light sources/spectrums, it's given me a huge increase in production and the CMH tech is suspected to reduce flowering times, which I've also seen. Trying to lock down the process I used in my first round with this config, and reduce variables for this run to see if both of these factors hold. The last round knocked 6 days off flowering for a same strain, clone from same mother, with all other variables/process being equal, other than the switch to CMH for flowering. idk exactly what's going on as you know it takes time to prove out theories in this game but so far this combo is looking really good. I expect to hit 1gpw this current cycle and hoping for as high as 1.25, in the same or shorter timeframe, that would be f'n awesome.
