"Assuming" a well controlled growing environment with near unlimited heat removal capabilities....what is the upper limit of lumens/lux per square foot?
Assume a CO2 conventration of 1500ppm and a ambient temp of 80-82 F
I understand that 1 1000W HPS is often used for a 4 x 4 area, has anyone tried 1500w or even 2000W per 4 x 4' area?
Also, what are your opinions on using only a HPS bulb for veg and flowering? I've heard arguments that either MH or HPS are better.
Thank you in advance for your responses.
