Scientific improvement on yield and potency

just out of interest how many plants did you grow

who are u asking?

Something else that came to mind was large amounts of UVB is absorbed by ozone in nature. What happens when we introduce ozone generators for smell in our grow rooms?

We don't use ozone generators IN our growroom, we use them to treat the exhausted air as it is leaving. Using ozone around your plants will rob the plants of odor, too.

On another note, one thing I remember reading about UV tubes is that the UV rays are good for close to a meter away from the tube, rather than the 6 inches that light is beneficial.

HTH

other benefits of ozone though is that it kills fungus and other bacteria.... also heard somewhere act as a deterrent for spidermites.

You say you have a background in statistics.

If so, are you familiar with Minitab data analysis software?

I would try a designed experiment using a response surface design. Specifically, I would at least start with a face-centered central composite design since you probably want to "maximize" more than one response. There might be an issue because the responses would be categorical data and it would would be hard to get certified "panelists" to judge, say, "high" and "taste".

Then use stepwise regression to optimize the model.

Gather your data and use multiple response optimzation to get the "magic formula"

I suppose you could try to extract and quantify the THC and CBD content via GCMS or HPLC, but discreet access to that analytical hardware might be tough as well as finding a qualified person to use it and interpret the resulting spectra.

I am available for contract consultation if you want to PM me

I have an educational background in economics and statistics; so if anyone had any theories they would like to test on ways we can improve various aspects of our growing I would be willing to work with you and intrepret data on a scientifically sound level so we could setup experiments in whatever theory it may be.

Could be nutrient vs nutrient efficiency, EXACT optimal lumens for given strain, trichome development.... you name it - I can interpret the data to laymen terms in exact percentages of efficiency etc etc.

Hey Potlike, Great idea!! triggered mine I am trying to get a grower group together to do research. Statistics is not my strong point would be great to have you on board!! I have a thread in this forum

The problem with analyzing dope growing (especially over the internet) from a statistical POV is that a giant number of things sum themselves up to create a huge standard deviation of expectation value.. Thats why the show Numb3rs pisses me off so much.. If you know statistics, you understand the importance of variable control, and can't just send guys with guns somewhere after doing a tidbit of arithmetic on a partial data set..

Weeding through anecdotes has brought growing a long way though, and although I skimmed through alot, thats what this thread seems to be..

Hey

Thought I would drop a note, I was considering running an experiment using two separate Phenos from the same mother to determine "statistical consistency?" of each. Once the data is in, Finding, breeding, and crossing could result in an improved strain. You up for it?
I am working with Arjans Haze #2.

What do you mean?? Run some numbers through some stats software??

Sorry, I've been inactive for awhile everyone but if you wish I'll help out wherever I can. If you have any efficiency or data that you want me to run let me know or maybe we can do mutual experimenting.

I just did some math it would take about 181 CFL @ 13w each to = lumen output of a 1000w hps

Have to take into consideration that luminosity is increased due to the close-distance output of the light.

You also have to take into consideration the Photosynthetic Photon Flux Density of the CFL vs the 1000w hps and 1000's of other variables.

Who cares about lumens, you're not a city engineer planning a street light layout.. Whats the PAR ratio like??

i just planted my aurora indica seeds yesterday and watered them yesterday, should i wait till tuesday to water again or keep them alittle damp?

this really isn't the place for this question, but water when your soil starts to feel dry to the touch and water it until it comes out your drainage holes in the bottom of your container.
