**thats my FAV

I smoked some mexican sativa a friend of mine grew with barely any trichomes...barely a glitter here and there...was hallucinating cartoon like shit for 2 hours...some of the best I ever had...another friend with some...uggggh...kush something or other...sparkling like diamonds...made me hungry and tired...And i haven't ph'ed in so long...years...THAT MY METER TIP DRIED OUT AND BATTERY DIED

impossible for all reflected light to outperform in efficiency 40-60% direct light...the math kills their words dude...yep...one bounce and out when algebraic/geometrical math is applied...good crafty marketing though

Exactly. The one "tested" as the most efficient by this hydro vendor is also the most expensive. duh.....

There's a sucker born every minute.....

And furthermore the shape of flash lights' and headlights'reflectors is to tightly focus the beam hence the shape...NOT efficiency...but in growing focusing is only part of the goal...a good EVEN spread is paramount....most street lights, which are primarily HID are HORIZONTAL...the newer ones anyways for efficiency and spread

 

[dizzlekush]

I really don care if you cant grasp the concepts and math of EMR physics. Just because you say something is impossible, doesn't mean thats true or you know what you're talking about (actually its proven the opposite in your case).

There is no better methods at testing the efficiency and output of a luminaire setup than testing the units PPF(D)/watt. This is science, where facts, not opinions rule the world. I can practically guarantee that you decided WITH YOUR OPINIONS that the FACTS WERE INCORRECT. is that how an intelligent person goes about learning? nope that's how a pothead does. You really think they pulled a fast one over Dr. Bruce Bugbee (2005 agricultural researcher of the year, founder of Apogee instruments) You really think the company Phillips would spend hundreds of thousands of dollars to collaborate with Cycloptics if they weren't on the cusp of science?

I guess it would be better to go buy Jorge Cervantes book right guys? as UB claims its got the best chapter on lighting UB has ever seen. open ended parabolic adjust a wings are the best reflectors right? Funny to see UB falling into the group of uninformed hippie-dippies he so loves to degrade.

Im not talking about the shape of the reflector, im talking about the orientation of the bulb inside the reflector. By your logic every flashlight & headlight manufacturer IN THE WORLD could improve the intensity of their flashlight/headlight by changing the orientation of the bulb inside the flashlight/headlight so that more direct light could be emitted from the flashlight/headlight. but why haven't they? STUPID FLASHLIGHT & HEADLIGHT MANUFACTURERS!

"A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it." - Max Planck "Believing that your hypothesis must be correct before all the evidence is gathered encourages you to interpret the evidence selectively. This is human nature. It is also precisely what the scientific method tries to avoid. It does so by requiring that scientists not just test their hypotheses, but try to prove them false." - Gary Taubes "You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe." - Carl Sagan "The more I learn, the more I realize how little I know." - Attributed to Socrates

Works for me, see my gardens (gallery). Let's see yours.

FYI i currently use horizontally oriented reflectors (Blockbusters) since there isn't a single vertically oriented reflector on the market at the moment that is worth its price. Since the advances in reflector designs are fairly novel, they're still a little overpriced for their actual value.

Now wait a minute. You pumped up the virtues of having a dead arc pole pointing toward the canopy in your super duper parabolic/cone type reflector and even though this design is supposed to be the best thing since sliced bread, you're not buying it cause it's overpriced? Did a cord come with that Blockbuster horizontal hood?

Don't know about you, but I'm buying light..... or was. I grow only outdoors now.

WOW, yep those six pictures you have in your gallery that are years old really prove a whole lot UB. better listen to you about EMR physics!

BTW watch out for one of the article's in that link:
EFFECTS OF RADIATION QUALITY, INTENSITY, AND DURATION ON PHOTOSYNTHESIS AND GROWTH
By Bruce Bugbee

Its written by one of those "suckers born every minute." One of those suckers that has over 50 published works in scientific journals, has received the 2012 Governor’s Medal for Science State of Utah Award, the 2005 Researcher of the Year College of Agriculture Award, the 2001 Outstanding Graduate Mentor Utah State University Award and the 2001 Top Professor Award Utah State University.

O BTW that 'sucker' has personally tested the Cycloptics luminaire and admits that its the most efficient luminaire that's ever been made.

There's 8 pages. Guess you got lost.

We've heard the rhetoric, now where's your garden?

 

[PJ Diaz]

where are the results located PJ? Also was the PL Lighting Deep reflectors tested? I am running 2 on movers and by far the results are quite astonishing compared to the sun 6

Here it is. The test was done by Greners. They only tested about 20 different hoods, and the PL Lighting Deep wasn't tested:

UB

I never pumped up any virtues, i corrected an incorrect statement that you made. And yes i do not think the 100% increase in price is worth the 5-10% increase in irradiance. Id rather wait a few years for the price to come down.

Wait you only grow outdoors? why the fu*k would anyone listen to you when it comes to reflectors then?

How would pictures of my garden make any of the science ive linked to more or less credible/valid? This isnt an argument over who's got the best camera and genetics, its a scientific discussion. Dont bring a knife to a gun fight. Attempting to handle me cuz you cant handle the science?

Oh, BTW theres not a single luminaire in the world that has >45% direct light so you are comparing the luminaire to things that you just made up... how intuitive.

[zack66]

Well, back to the original post about fan leaves. This is my first indoor run leaving them all on and it payed off. 9 weeks flowering purple kush. All leaves left on.

 

[dizzlekush]

thank you PJ

I already gave you the link to that in the post you responded to attempting to 'debunk'. did you really not even read the links i provided? wow this proves such a point, one that you'll prolly never get.

ooops...I am so sorry...seems you know it all...so I will not waste anymore time trying to educate god

I don't pretend to know everything, but i can almost guarantee ive spent more time doing legitimate scientific research on the different sciences of horticulture than almost anyone who visits a cannabis forum. This doesnt make me better or smarter, just more informed on the subject. Id suggest checking your ego at the door so you could learn something too.

 

[dizzlekush]

BTW to address the topic of this thread. i 100% agree with UB's position that defoliation will never increase yield. I have had one pheno of "Whitakers blues" (dj shorts blueberry X quimbly) that had such copious leaf output and such a low yield that you could remove a decent amount of the foliage without decreasing the genetically determined pathetic yield, but the defoliation never increased yield.

sorry you feel this way...I have spent more time GROWING MJ than you have probably been alive...think of your above statement...If at least 50% of the arctube in a horizontal fixture is visible then it equates to at least 50% direct light emission...and research or reading? EXPERIENCE not only reading...and with all your supposed research you only found less than 40 things to share in 2 years...whatever dude...last words I waste on you...have a great existence
