They would produce the same heat. But LEDs only require half the wattage or so to equal the output of an HPS bulb. So you should be asking "how much cooler is 350 watts of led compared to 600 watts of hps?" and the answer is about half as much heat....

Typical HPS diehards lol. Claims all of the data is bullshit, but provides no insight into why or how. But if they want to live in lala land and say that.... then they can have fun with their power sucking, hot as hell, shitty orange spectrum lights. Here's some quotes that shed some light...

Not my pic. I just wanted to clarify that QBs penetrate actually better than COBs do and a picture would be a good way toat least show it isn't the otherway around. He used 80% QBs and 20% cobs in terms of wattage. But you should read the post i made with the 2 pictures above... It's a...

Ill just leave this here. This is lighting 101 guys. http://www.lighting-essentials.com/01-lighting-class-light-principle-one-size-lightsource/ Now put a nail in this coffin and just accept that cobs simply cannot penetrate as well. It's a fact. Sorry to rain on ya'lls cob parade... HLG...

What I thought....

Ofc not. But ive yet to actually see a legitimate 3lb pull from a 1000w. Only people claiming they get that. Prove me wrong. There are however people pulling 4 pounds plus from 900-1000w of LEDs. I always see 1000 grams from 1000w dehps max. Never been able to find pics of a grow that goes over...

Explain how it's not true then. I will link a study that proves it... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4559655/ "Plants use diffuse light more efficiently than direct light, which is well established due to diffuse light penetrates deeper into the canopy and photosynthetic rate of...

Lets see 3lb a light then. Because they werent hitting that in that commerical grow. And they were using LEDs. And better quality bud. I would love to see anyone who has done 3lb a light using HPS/DEHPS. And not just say they do. AC is that bad on a commercial scale... A 1000w dehps per 5x5...

It was 80% QBs and 20% cobs in terms of wattage. But you are correct. And none on my own. Did help my friend get a 600w build setup and through clone to harvest though. Only on week 4 of veg under my own strip build... Doesnt really matter though to the topic. Never said COBs cant grow big...

No, did you not read my post? I cant wrap my mind around why people can't understand penetration. How does one grow long ass colas dense down to the bottom? By having good penetration. So if one light setup can penetrate (much) better than another, it will be more able to grow long, dense...

It's funny you want to call it bullshit when all you do is respond with useless remarks. If im wrong, then prove it. Do the math yourself. Typical HPS fanboyism. Watch this video and learn a thing or two. This is a MASSIVE vertical growing facility and they swapped to fluence spydr x lights...

As ive said before, i dont use COBs. But science/physics dictates that QBs/strips that provide more uniform, diffused light will penetrate much better from giving many more angles for light to go through the canopy. And since the diodes are way more spread than on a COB, you can get mcuh closer...

Never used anything but 3.5" square til now. But i see how it can boost yields. It allows more a more even canopy and I feel it promotes lots of tops by spreading the branches better. I also have noticed really small squares (like >2") seem to force more tops as the leaves/nodes are forced to go...

It's overpriced. All their products are diluted to shit. And they seperate EVERY single one into a seperate $20-30 bottle. Their beneficial bacteria products have been lab tested and found no live bacteria MULTIPLE years in a row. They do not work any better than any other line. AN base trio...

I usually just top once before scrogging. But i also usually use 3.5" squares and not 6", but i ordered the wrong size. You cant see in the pic but there's probably 30 baby nodes all over that will fill the scrog with budsites in no time. I will lollipop right before flower and 2 weeks into...

3x3, with 320w of diy samsung led strips. 1 plant in 7g fabric pot using fox farms ocean forest. Also using Recharge.

What do yall think of nectar for the gods? I have a good understanding of how it works, incredible stuff. It's like putting super soil in it's plant available forms into bottles, and then hacking biology by binding the ions with calcium and forcing it into the plant. I hope yields are...

QBs/strips can grow bigger donkey dick colas than COBs easily.

Just another quick update. The n tox seems to be getting better and got another 2 inches of growth since yesterday. I dont know what that nectar did but god damn ive never seen veg this quick in soil.She's at the scrog now. My humidity is going up just as expected. Ambient in my house is 25%...

They are shit. And i used to use them and could pull 1.3 grams per watt using them. Dank quality too of course. And I will tell you they're shit.
