Hello all.

This is not a competition, this is a compilation of GPW
Purpose is to gather quantifiable data on light sources efficiency and mediums hopefully limiting the superfluous questions and establishing consistencies with light sources, strains and mediums.

The only method of calculating GPW i wish to collect and will list is cured and trimmed product divided by the wattage used to produce light during your flowering cycle. i will repeat

Grams of product divided by watts of lighting
G/W

the reason for this method for GPW is because i can eaisly collect data on this calculation method and not on total system watts or veg time or any other method as simple as this. I am interested in efficiency so if vegging for 6 years is worse than 6 hours it will be compiled and you will see generals. yes there are many variables but im creating a general system.

I believe this to be self explanatory, please don't prove me wrong. HOWEVER health for brevity I would like it in the format of FL for flawless, SP for some problems and P for problematic

Please copy and paste my format then fill it in.

Strain details and number of plants

Light description

Medium

Grams of cured trimmed product

Watts of lights used for flowering

GPW

Health of plant

VEG time

Thank you and please post up and i will either use excel or another easy read format for comparison. feel free to PM me for suggestions

ahh I didnt clarify we are only using wattage excluding driver and what it actually draws as with a 1000w Hps its really pulling 1070 so your osram is only 100 and no clue what veros are but i only care to use actual draw +/- driver so your osram is 100

No sorry we're unable to do that people have asked before users get 72 hours and that's it sorry

Hmm. Ok.

What if I messaged the picture of the compilation every 3 days or so and a moderator adds it in? Is that possible?

You could certainly ask
It would be up to moderator discretion at that point to say yes or no
 
Mix of varieties
CXB3590 + CXB3070 @ 25W ea with passive cooling
Recycled Organic Living Soil (ROLS)
715.7g from a 4'X5' canopy
532 dissipation W averaged over 8 weeks
1.35 GPW
Some were slightly underferted/early fading (still experimenting with the soil mixtures)
VEG time 8 weeks (intentionally slow veg time required to keep timing in sync)
