To grow weed effectively, you need between 25,000 and 50,000 LUX. As you can see, a horizontal system does in fact lower light intensity at the plants by the same proportion as the increased area.

Therefore, the only possible benefit of a vertical system is the 5% or so that would otherwise be lost by a reflector.

Sorry, chart will not past. See it here:

Gr8 but i am still a Pervert (meaning i perfer vertical growing) tranlate that 5% in to $ for me
and in my mind that chart is wrong with respect to perverts
and remimber where you herd the term first i started Pervert i plan on coming up with a club icon and starting a grow club when i start my first vert grow

You can also find this info on wikipedia or any other source. LUX is Lumens / m^2. So the intensity of light decreases in direct proportion to the area being illuminated. This is an absolute. A vertical grow only increases harvest by the amount that would otherwise be lost by the hood. If you have a top notch hood like the Adjust-a-wing you are looking at 3%.

if a 600w light gives 1.00 foot (12 inches/30 cm) 9,000 fc at that distance and 1.50 foot (18 inches/45 cm) 5,600 lumens if u increase the distance for 6inches,then if u mesure the distance from the bulb to the reflective surfice of the reflector and back thats about 6inches so u lose about 25% in that direction and what about the lateral reflection there again u loose according to the distance the light has to travel,u can mesure it and see

You are misunderstanding how it works. Light decreases according to how much surface area it falls upon. As you move a light further from a surface you increase the area illuminated. Say you have a 600W HPS illuminating a 4'X4' area (16 sq feet), then you raise the light to illuminate a 6'X6' area (36 sq feet). That is over 2X the area so your light intensity is cut in half.

The formula for intensity is Lumens / M^2 (of floor space) = LUX. The fact that the light travels a few extra inches from the bulb to reflector and down is irrelevant. You only lose around 5% with a good reflector.

Honey??? Have you ever taken any type of organic chemistry and know the biometric composition of honey? I would recommend noone use this! By the way, you have eagle talons going on, might want to address that!

Oh my friend.

I have read so many charts of different types over the years and heard the so-called " expert opinions " from Man's World's most bright and educated and I still just smile and shake my head.

Intelligence and common sense comes from within and I was Blessed with copious amounts of it.

In other words, I listen to my body and it tells me if what I put into it, is good for it or not.......that applies to my plants also.

I could care less about anything that was written up by some educated guy out of a school somewere.

Common sense, will always win in the end.

My number one ingrediant to life period is.....LOVE and Understanding Of The Truth.

Most people reject the last statement.....when it is brought to them in any form.

Truth just scares some people, because it requires them to blame themselves.....

Raw Honey is insane good for you and your plants.

Sure, you need to purchase the honey from someone who does not live close to cities and major dumping areas, but it can be done easily, with a little time and effort.

Cured many things in the Human body and other organisms, by the use of Pure Raw Honey.

Cured four incurable diseases within my own body, by using Common Sense of Nature and the Proper application of Nature into ones life.

All the Bull Hockey medical charts and expert opinions........was killing me.

I woke up to Real Truth, about life and plants and all other things in nature.......became a part of them, instead of being seperate from them.......and I am alive and healthier than I have ever been in my life.

No disrespect.......but you boys and girls can keep all of your studies and charts........not interested........my chart is from Nature......my code is Common sense.

Blessings,

Rev. TheNatural

panta
is 100% right even if you had a 100% reflective hood you would loose lux and lum when you raise the hood to increace the lights footprint the plants on the outer realm of the lights footprint would suffer- this is not true with vert growing

rickwhite-
if you take your own formula for intensity the no. you enter for (floor space) you would times that ceiling and right and left wall
if the foot print for a light (X) with hood is = to 3ft by 3ft
if you remove that hood and place light on its side you could have 4 times the footprint area by placing another 3x3 in front , behind, to the left , to the right of the light (4 dimensinal growing)

I am sure there is a light equation for % loss due to distance from target, not just how it spreads..
