Not if grower 'A' has his hung 4' above the canopy and grower 'B' has his hanging 6' above.... both systems being identical.
There aren't two 1000W lamp systems that when measured with a quality f.c. light meter will register the same lumens at the same distance from the midpoint of the lamp. The age of the bulb, type of hood, distance from the canopy, garden profile and many other factors play into what the plant actually uses regarding photons for photosynthesis.
It was a joke on noobs.
The LIGHT in YOUR garden is always constant its the light YOU are using!! What are u talking about its diferent in everyones grow? No shit. GPW is a measurement regardless of a 400-600-1000 w etc... Using a standard MH for veg and HPS for bloom, you should have a target range of producing 1 GPW on average for most strains give or take depending on the variety. Some will produce more, some will produce less.
BUT, if YOU are running the same strains continuously in YOUR garden using the SAME light source, THEN measuring GPW regarding yields is a good measurement. Wsp w this every garden is different BS? It doesnt matter what u are running. If u got 600w lamps u wanna get 600 grams per bulb. If YOU run 1000w bulbs you want to try and get 1000 grams per bulb. Whats so difficult to use that as a standard of measurement for yield? Its the perfect measurement because in YOUR garden its the only constant variable throughout your grow besides your room size which is also gonna be constant. It doesnt matter what anyone else is doing for lights or room size. LOL what are u guys talking about?
A 10 x 10 room with 2 (1000w) bulbs u wanna shoot for 2000 grams.
If your running a 12 x 12 room with 6 (600w) bulbs u wanna shoot for 3600 grams or 1 gpw.
It dont matter who joe blow is using for bulb size or grow room space. Its a target and standard for yield. Almost every seed company on the market uses GPW or Grams per sq/meter because the footprint of your light covers X amount of space. Which is usually 2-2.5 sq meters. I showed u the breakdown that GPW and Gram per sq/meter are almost identical. Therefore if GPW wasnt a good unit of measurement then the math for Grams per sq/meter wouldn't have similar/identical results, BUt IT DOES, because it is a useful measurement of YOUR garden and yield in comparison to your light output.
HUH? Idk where u guys r coming up with the stuff.. U need to break down where ur coming from because I am lost by u telling me that the light in my rooms arent constant when they are all 1000w bulbs that NEVER change. GPW is GPW it doesnt matter if its 1000w or 600w your yield is gonna be smaller on 600s compared to 1000w everytime because its double the output, lol. What r u guys talking about? Seriously confused for real, making no sense period.
