If it were any closer, the plants would suffer greatly or die from heat stress. The MH is 14" higher than the LED, and has almost 70% more wattage, as well as a much greater potential to carry light energy over long distances vs LED. I've known plenty of growers who only use HID, and most of them run between 12" and 24" from their plants, so I don't see the height as an issue.
well seeing as you've been gardening for years, which at your peak you were running 4000W you should know that cooling is damn near just as important as lighting in the first place. if you shove a 400W light into a 15" x 15" area with no cooling, then hell yes you are going to have problems that include slow growth and discoloration due to heat damage and heat stress.

and since your site is "different" than all the others out there, and you start at "square one" for all of us not so smart types, you would know that light is governed by the inverse square law that states "The intensity of light observed from a source of constant intrinsic luminosity falls off as the square of the distance from the object."

if one were to double the distance to a light source the observed intensity is decreased to (1/2)2 = 1/4 of its original value.

or in layman's terms, light intensity is directly,squarely proportional to the distance at which said light is placed from a receptor of light, such as, oh, let's say a leaf.

so, with that being said, the placement of your HID is TOTALLY relevant to the performance of your plants.

care to differ?

by the way, you will notice that for the most part i have no ego. i have only been growing since last October (not quite long enough to develop this ego you speak of). if you go do some research you will notice that i take pride in SHARING correct information, giving positive feedback and helping all those that are willing to accept it. i also like to push the envelope and dabble it things that are well over my head. but never, not once have i pushed something down someones throat. if you want to do it right then start a grow log. post pictures of YOUR side by side comparisons. don't post pics of others grows and say they came from your products.

and frankly, i could care less about those other sites you are involved with. this is my HOME! these are MY people. and i'm not gonna let them get ripped off or get bum advice by somebody trying to make a quick buck. if your product is as good as you say it is then you won't need to say anything!

like i said, send me some units and i'd be more than happy to do some grow logs and INDEPENDENT testing! as i'm sure many others on this site would do. and those people will be the first ones to go to bat for you and your products should they live up to the hype!

i believe that puts the ball in YOUR court!

not to mention, most people that adapt to technology early DO their own research. don't think you're the only one that can send emails to china and get products exported.
