AMERICA\'S #1 We should all be proud of this great Country. It is just upsetting that laws prohibit us from growing certain flowers in our GARDENS!!!!

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.

...but I'd have to say that 4x4' or 4x5' could be lit by a 600w, going 1000w seems like wonderful, glorious overkill I assume that you're using the MH for vegging and the HPS once you flip it over to flowering... Use a rectangular reflector if you can... should light the space more evenly, though ymmv.
And can't remember exactly where I heard it, but something like 7,000 lumens/sq.ft is good, 10,000/sq.ft. optimal, and anything over 14,000/sq.ft. theoretically 'too much', but if bmwboy713 was pushing 18,000 and making it work, well, /wow/... I hope you were wearin' sunglasses while working on that killa show, mon!

I know for plant biology that the ammount of light can be too much for certain plants. Good example is Melissa officinalis. Too much light changes the color of the plant to purple wich is cool thought. Grows natural and green if kept behind a window but turns purple already under 21W 6500K CFL(1300 lumens/lux).(tested this myself)
But for cannabis being grown naturally in deserts near the equador. High concentration of light would also need high concentration of other components needed for fotosynthesis?
If i had a laboratory i would be runing tests for diffrent combinations of light+nutrients+Co2+dark time.
Natural co2 levels are around 300 ppm ? and natural light is
10,000â??25,000 lux Full daylight (not direct sun)[2]
32,000â??130,000 lux Direct sunlight
(copied from wikipedia)
lets say we want to simulate best outdoor conditions inside we would need atleast
25000-35 000 lumens per square feet of plants.
We would need to match the nutrient usage at this intense light levels correct?
Lets keep in mind that man made light does not match the full spectrum of light gained from the suns rays.
So maby just maby only one type wavelenght of light could be too much if high enough concentration right ? can anyone confirm this ?

Hi all....I'm new here but experienced grower and I have about the same size room/closet. I have a 4wx6dX8h foot closet, 400W HPS and 400W Sunlux for flowering. I have attempted to multiply the light by adding 6 large mirrors. It seems to have worked! I may/may not have 4 AK47s, (had 6, but 4 fill the closet to capacity) now in 1st week of flowering after about 90 days of veggin. They are about 4 foot in 2gal containers in MG soil. I have them staked and am trimming for a (hopeful!) mega yield (saw pics and desc from an Ed Rosenthal book) I won't be posting pics prolly, and I'm not exactly sure what defines a monster plant, but these are some thick bushy stinky babies...yes, I call a four footer a baby! They've been fed MG with every watering. Bottom line is they are very, very healthy, so get bz planting and good luck! The longer you think about it the bigger they coulda been!
No matter where I go....there I am! It never ceases to amaze me!

I would go with the 4x5 and then supplement with 2 t5 8 bulb of the 2ft variety. get the bulbs that are made for the flowering stage and orient them vertically on the 2 longest sides of the garden. this will give the unlit portions of the garden a huge boost and help you to have buds that all mature at the same time. this is assuming that you dont mind coming up with the 300-400 bux for the t5's. I am running a 600hid with a dual spec bulb and a t5 2ft and the undergrowth areas are growing like crazy. there are very few spots that do not get direct light and i try to rotate the plants by hand every day or every other day about 180 degrees. as soon as i can im gonna pick up a 4ft t5. ppl tend to underestimate the power of t5 bulbs.
