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.

if you get bored enough id like to know what the exact % of cost of ele used to bud would be from this grow. its not a big deal just kinda wondering
CFL vs FLORO vs HPS

can you be more specific ?
Are you meaning cost of materials to grams of bud per yield? If so that wouldn't require hypothesis testing or regressions but I would be happy to figure it up for you.

im sorry im 1/2 assed stoned,. what im trying to see is how cost effective each room was based only on ele used. so yeah i guess the cost per gram would work, or oz. doesnt matter to me its just something ive been wondering and im really bad with math. all my cost figures where just ballparks.

yeah my roommate and I are baked too- i love graduate school


if you want that I need your costs outlined and a grow to compare that to using similar parts to be a true test


ps: love the monkey picture in the profile


-pot . . . . st0ned

ok lets see, i used
6 x 13 watt cfl lights 12 hours a day for 6 weeks and yielded 1.25oz/dry
1 x 1000 watt HPS 12 hours a day for 6 weeks and yielded 2.25oz/dry
decent hydro goes for about 200 an oz around here, and my ele is 14.6 cents per kwh. i think thats all you need but i might be wrong. let me know if you need something else,,,, thanx

P.S.
my monkey parties like a rockstar lol

Get to work schoolboy! j/k

lol he offered,,,, i just wanted to see if he would really do it

CFL:

6x13x12=936 watts per day

6 weeks * 7 days a week = 42 days

936*42=39312 watts per growing period

39312/1000= 39.312 kw per growing period

39.312 x .146 = $5.73 per growing period on CFL lighting all other things equal

5.73/1.25= 4.58 per ounce in electricity

HPS
1x1000x12=12000 watts per day or 12kw per day
12kw per day x 42 days =504 kw per growing period

504 X .146 = $73.584 PER growinrg period on hps all other things equal
73.58 / 2.25 = $37.70 per ounce on hps

4.58/200 = .0229 or 2% of street cost CFL
37.70/200 = .1885 or 18% of street cost HPS

16% differential in cost


hrmm that is VERY INTERESTING

as I said I didn't do any hypothesis testing or regressions but this looks significant enough to look into

to conduct that experiment properly I think we would need to run them side by side at the same time and make sure nearly everything else is the same as far as dimensions and equipment, nutrients, venting, humidity, ph etc etc.

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

13w* 181 = 2353/1000 = 2.35 kw per hour compared to 1 kw per hour from 1000w hps

that would be rated at 145,000 lumens each way

it would be interesting to see what yields are produced at each level then getting true price per ounce with everything else close to equal

other issues would be the quality of the bud itself? Are the buds on each tight and compact? Tons of questions here - let me know if you would like to further this experiment with me and we can come up with some real results

Wish I could publish this for my vita- however, I am afraid the academic world wouldn't really appreciate my fondness for herbal cultivation.
