Light Quantity vs Light Quality Evidence ... Just for 4 u gg lol!

To me the leaves on that second one look pretty burnt. Not light bleaching but like they were dried out by heat. Maybe it was both?

I've pulled honest to goodness 2 pounders from my COB LED runs. Recently I got 25oz from a plant grown in a 5 gallon bucket of soilless mix and fed my standard recipe of dry hydroponic nutrient salts.

People can tell the difference between COB LED grown product and that grown under my 860W CDM Allstart lamps- from across the room.

Frost, density, weight, aroma, flavor and potency are all better. This isn't just my own opinion, it comes from all those who've looked at and tried both.

Thanks for the input ttystikk and brilliant results btw

Your posts sounds like it has the potential to be a really good indicator, are you using more/less/equal amounts of photons compared to 860W lamp?

Left long enough the leaves will eventually develop what looks like burns, this is a result of the leaf dehydrating because its internal system can no longer function, so after a while it will start to dry up. External heat in this case only serves to expediate the collapse.

Your grand opinion of how science and technology work is getting ridiculous. I just can't let mis information like this go.

To be fair his post isn't wholly inaccurate because heat does need to be carefully managed in the growroom and HIDs are a pain in the butt when it comes to heat management during the summer months, but equally not enough heat can slow things down considerably hence some may have struggled with this e.g using LED setups in winter and finding they needed to add heat into the growroom in order to achieve optimal growth rates.

Correct me if I'm wrong but it is a lot easier and safer keeping a COB room warm than it is keeping a HID room cool.

@TogiX you will get no argument from me on this onel

I deliberately matched WATTS, because I knew that less than 40W/sq ft of HID lighting wasn't adequate and I was tired of dealing with less light than I needed. Sooooooooo now I have borderline too much! I can't win! Lol

I'm absolutely sure there's a lot more photons flying around now than before but I confess I haven't done the math. Ballpark is 'about double' vs the old lamps.

The difference in heat I've seen is due to HID's being more centralized and COBs more spread out. ( COBs on a panel are generally spread out across like a 2x4 fixture (or whatever size) whereas HID is all coming from one central point (mostly the bulb). If the lights are viewed as heat, it's more efficient to heat a room with ( 50w heaters spread out than one 400w heater in the middle of the room.

Not really sure what you mean by 'safer' though. Safer for the plants? For the lights? Against fires?

Personally think heat index is a better way to look at the grow room, humidity plays a huge part in things, each light will affect humidity levels as well.

Inadequate warmth in winter is an INSULATION problem, not a lighting problem.

We can use air cooled hoods to remove the "excess" heat from our awful HPS bulbs and have them run as cool as we want. My 315 open reflector is putting off the same heat at least and has to be blown away from the canopy and exhausted which is not as efficient in my little room.

Also the HPS bulbs many of us use have a much better spectrum than an old streetlight and grow fantastic plants. And although I have seen an improvement from the ceramic bulb I believe it is the Uv that is causing the potency and psychoactivity increase as there is only a little more blue light.

And the blue light in a Hortilux Super HPS has already been increased dramatically.

And your ceramic bulbs have a better spectrum, intensity and some Uv over your cobs so if the weed isn't better under them than your cold cobs you are doing something to affect the outcome. Or your room is not right.

Results are as such in our industry ty.

HPS last. Then enhanced HPS and metal halide. Cobs next haveing more terpenes on average and first for everything in lab tests is ceramic metal halide. Best spectrum and uv. And an average of 4% increase in thc.

You could grow better weed (if you are good enough for the light source to matter) with a good bluple and some t-5's.

I have not even seen a recommended horticultural light yet that has cobs. Only on weed forums. But I will concede that HPS started as streetlights too and advanced. And cobs may too.

And the other led is too. But they are going with specific wavelength bulbs in addition to full range "white" ones for the best spectrum for plant growth and it is adjustable for different stages.

And it took a few days of observation to get amazing results from my new LEC 315. I must have been confused because of the amazing change in growth. Lol.

And you should know. My Hortilux 600's grow a bigger better put together bud and with more penetration through the canopy for better developed buds all through. The ceramic as stand alone would hurt my results. It's weak for intensity. They are better for supplemental lighting. Or I need twice as many.

Sorry man. But you say you have 30 years of experience and are involved in the industry in one post and you don't know basic electronics or basic plant science in the next.

And none of your plant pics show a plant healthy enough for you to determine results of any kind.

I have been trying to be nice after another forum expert got upset with me. But he has no real results or actual knowledge either. You are the resident Cob expert on his website aren't you?

Some people have 20 years of experience doing what they love. And some people only really have 1 year of experience repeated 20 times.

That's what you forum experts are like. All of the info being argued is out there. Weed has not been an unknown cultivar for many years.

Maybe 20 more years will help?

Posts like these are why you stay on my ignore list. It's clear you've already decided, facts be damned. Enjoy!

This is all growing environment 101 so to speak.

He just finished arguing with me here somewhere that I shouldn't use my HPS to heat my house in winter as it is inefficient. The other benefit is obviously a proper warm grow room. He is an "efficiency expert" but can't understand my lights offset my propane heating bill by over $500 every winter. He just has an agenda because he spent so much designing and building with the cobs. And they didn't fix his problems so he over sells them.

He has reported he over cooled his room with his water cooling and now suddenly after a lifetime of pot growing learned cold rooms hurt growth.

My response is meant to blanket all of his mis information and fantasy.

And I owe his silly egotistical forum expert ass from his condescending rudeness this summer. When he also had no idea what we were talking about.

Plus he showed his plants a lot lately after talking up his professionalism, creativity and results from experience. Have you seen them? I would listen rather than talk if they were mine.

I remember that.

And saying water cooling is not needed / completely overkill hehe.

No, it's still needed, just dialing in the correct amount of heat.

It's a false economy to use excess electrical power to make up for inadequate insulation. In Michigan. In winter. Derp.

Oh, you don't like it when I check in and call your bullshit, nevermind your attitude?

Deal with it.

Better yet, fucking grow up. It's not like EVERYONE ELSE is the problem and you're perfect, otherwise you'd still be on riddleme. Wouldn't you?

 

[sixstring2112]

That first picture is also exactly what severe light bleaching looks like. A true albino should have those types of buds all over the plant

 

[MichiganMedGrower]

Why? The lights keep the room warm and are all on high temp cutoff switches. And the ballasts have individual fuses and so does the controller.

I would need space heaters day and night in my old house without them.

You still haven't figured out propane heat in an old house in the woods is very expensive and I run my lights at night regardless. It is free heat.

Why do you defend what doesn't need defending?

"Derp". Try learning something before you comment. We have had a long discussion about this. Really long for someone who ignores me. And you still haven't learned anything.

I quit that useless website. I was looking to learn from experienced experts. and in a few more weeks we will know how good the riddlers prized genetics are. I am growing better versions of some of them than they are.

Oh. And I like this. I don't mind at all. Feel free to comment on the open forum any time Tty. I sure plan to.

And I never said anyone was a problem except for you and RM3. I liked most of the Riddlers. I don't like rats. And I don't like self proclaimed "experts". especially when they refuse to learn anything.
