Growing and sharing with friends is a great way to get busted if you let them know you are growing. People talk.......ya know ?

P.S. Clem, you prefer parabolic, huh ?
You know I actually have both of those charts on my computer, but thaks you for reposting them, they took some searching to find the first time.

Also I have a total of 3 friends in this state, I brought them with me when I moved, we lived together in the woods for 6 months, and for the years after that we have lived very near by each other. Normally I would agree with you on not letting friends know, but these friends are the rare type that a person can actually trust, we've been through alot, and they did'nt narc me out of rip me off on any of my other grows. So it's cool. Besides I have personally seen too it that they know their rights, and what bullshit the cops will pull to try to get a person to give up thier rights.

I do appriciate the advice though, I've told the same thing to many others.
peace

im not saying less light is any better but this articale that i just got done reading in hightimes jorge cerventas grow guide i may make a thread of this later but i dunno its called yeild of dreams it says this guy james is says hid lights couse lots of heat and with that heat come lots of problems in a growers space temps should be around 75 during day and no less than 55 during night he has came up with the following he has he says this way yields two times as much with less light he uses he uses 10 hps lamps he messed with numerous different light patterns light regimes ect ect and found that the zig-zag way is best he switches 5 of the lights on 2 hours then the other set so each set of lights are on 2 hour intervals and that way he cuts his bill down by half and this is wear it gets very interesting in order for this system to work properly you need 4 lamps his first grow yielded 9.3 pounds around 70% of his last crop as he started to get the hang of this light regime yields started to climb in a diff grow op from two ladies they do the same light regime that james does there grow was perfect till it cought a virus and they were forced to harvest 110 healthy plants two weeks early only 7 weeks into flowering when dried and cureed there yeild was 4.8 pounds givven the total amount of wattage(600 watt hps) they harvested roughly 0.7 grams to the watt for every 30 days of flowering everyone knows the bechmark is 0.5 grams per watt each 30 days it goes on to say this was a major improvement there next crop yielded 3.1 kilos of dank from 150 plants 0.7 grams for each watt for 30 days of flowering(1.4grams for actuall time flowered) however the yield was low becouse they didnt grow the clones long enough these polish dudes are currently using this light regime and getting 1.6 grams per watt for every 8 weeks of flowering if you want to get full deatails of this you should go to hightimes or get the mga

That is great for a scrog system, the best I have ever seen was /is 0.6 g/w/m Getting 0.7 g/w/m is one hell of a imporovement. Scrog is the only way to go, but the damn plant count is the killer, in the U.S.A. FYI a plant can be 10 ft tall or a leaf with a root, been there done that. Once again that is extreemly good job of growing and may try it with a new system. With automation its real easy, to pull it off.

i think the question was what is too much light? i've used 6-1000 watt hps lamps over a 4x8 before in a SOG grow before and had really good results. No staging, just straight 12/12 18,000 lumens per square foot. But you have to remeber plants can only use as much light as they have available co2, they can only use as much co2 as they have nutrient, they can only use as much nutrient as the root have available air etc. everything needs to be in proportion, you can raise one w/o raising the rest to achieve the best results.

I've figured the numbers with 3 possible garden sizes 4x4, 4x5, 5x5. I'll start with the brightest.

4'x4' area=16 square feet or 62watts/ square foot
HPS=9,062 Lumens/ square foot
MH =6,562 Lumens/ square foot

4'x5' area=20 square feet or 50watts/ square foot
HPS=7,250 Lumens/ square foot
MH =5,250 Lumens/ square foot

5'x5' area=25 square feet or 40watts/ square foot
HPS=5,800 Lumens/ square foot
MH= 4,200 Lumens/ square foot

With some research I found a thread at marijuana.com that was saying the lumens to keep a plant growing was
Minimum about2,000 Lumens/ square foot
Mid-range about 5,000 Lumens/ square foot
Optimum about 7,000-7,500 Lumens/ square foot or higher
SOURCE= Lamp Lumen Data - Page 2 - The Garden's Cure

I know I've seen a thread discussing how much light is too much, but I cant find it, anybnody?
I'm thinking of going with the 4'x4' area to get the most intensity out of the lighting system but 6,562 Lumens for veg, and 9,062 Lumens for flower seems like I may be pushing too much light. But this may be suitable considering I want some big mother fuckin' (4'-6') plants, of the highest quality possible.

Also I'm thinking of going with Mandala's Kalichakra, and/or White satin. And I will be using organic soil. Probably a 2-3 month veg to get them nice and big.

Anyone have any thoughts? Ideas? Suggestions?
peace
So can you figure what's the best setup if you used a LED's Lights setup? Lumen, Kelvin and the PAR value to get the optimum results. In Hawaii we got Night Helicopters marking homes for a Heat signature? They wake you so early? before 5am so I figured if I can get from the Med MJ program I should do all right but I forgot about theives.

So I'm going to China to have them make me a Perfect grow Light? LED for ever

In 2001 the US LAW was changed were they can not use In-fared to get a warrant.

The Patriot Act Throws that all out the window if they want to bust that out. I do not think thee are a lot of Talbans in Hawaii

Well light loss per range to source is not difficult to calculate.
It goes down exponentially and that means double the range cost your lumens to decrease to a 1/4. Exactly.
However that does not take into acount leaves that shade or other distortions and reflections etc. But from light source to top of the plants it is perfectly accurate and a basic physical fact of nature. Same thing with drag by the way was a racedriver before. Double the speed = quadruple the drag.

Interesting thread by the way man. And ye I am very much into numbers, statistics and calculations myself.

the patriot act is a complete violation of constitutional rights. Also ensures people can not sue FDA & pharmaceutical companies in regards to certain vaccinations linking to autism.
