Have any of you DIY COB Growers finished a crop under 1000W DE HPS? - POLL

[RM3]

Its alright buddy. You COULD spend the doe for 48" LED t5 replacements. Theyre not as kick ass as cobs, but youd get A LOT more lumens snd ppfd.

Not true, but whatever, all the led tube replacements I've seen are bout half the lumens, not that it matters since plants don't care about lumens

Once you start down the dark path, forever it will dominate your destiny, consume you it will.

sounds like fun, and a bit like Yoda

 

[RM3]

@RM3 getting .85 grams per watt of pure fire like the pic above is fine with me too, if you're OK and your customers/patients are ok, then ignore @Yodaweed, keep using the T5, fuck these clowns. I'mma grow with my crazy hybrid beginner lighting system again because I don't sell a gram of weed and I'm unemployed right now. I can make more money in tech than I could in cannabis right now, and it is slightly less annoying to deal with computer nerds than overzealous idiots in the Canna-biz. Half of present company excluded.

Hell I mostly don't even weigh it LOL and give most of it away, same with seeds, I share seeds and folks share em back. Tis a wonderful thing

As long as 1 or 2 hits gets me blazin and last for several hours I'll be fine, only thing I've ever cared about is the high, fluffy/dense, pink/purple, fruity/skunky all irrelevant in my world

lets see here what these 2 plants will harvest in 2.5 weeks time they started 2 weeks in 150 watt HID then 2 weeks with 600 then flip 18 gallon wanna bet i do better then 1.5 GPW we will see i guess no till i will not be afraid to post results and i will with not just saying what i did but like this you know half pound baggies lol there beasts 1 liter sized stalks so couple weeks away and again only 2 plants View attachment 3641251 View attachment 3641255 View attachment 3641256 View attachment 3641260

Looks good, man. COBs are good lighting, though, not supplemental lighting. The post I was responding to, by you (right?), said that COB were good supplemental lighting. I meant to assert they are ready for prime-time, based on 1.4gpw from some random noob you referenced from the internets doing a 600W@ COB grow.

We are deep within The Narcissism of Small Differences at this point, but you can grow, I'm not hatin' on that.

I think all lights are valid, and COB are among the best, and soon (couple of years, no more than 5) will be the industry standard. That's my stance, and I'd like to see it refuted with data, but it won't be.

P.S. You're alright with me, sorry for fucking with you, unlike some I've already ignored up in here.

I have hatched some nice color for this year green house grow i wonder would i be better off using LED or COB or the SUN ???? lol

Cobs led Plasma hell there all really supplemental lighting as were trying to mimic the Sun yes there stand alone fixtures like many others and yes there efficient but they have no UV lighting like most LED unless its made for a specific application
as for my plants this is my first no till indoor so being live of course i could of done it chemical and really killed it in yield but with seasons and working on soils for green house i needed to start somewhere she has pretty much only have been given water i made my own line of nutrients which is being tested as well documented this years out Door pure 100 percent Vegan organic nute line thinking with the think green and the organic craze it might be a hit ...
In early stages of development lots of hills to climb before marketing if it takes off great if not woopy do

I'm getting plenty of UVA/B from my WavePoint aquarium T5 bulbs, ain't that right @RM3? I'm digging them, but they seem to wear out pretty quick.
That is a real limitation of LEDs, they are not good at UV.

Ahhhh the smell of fresh cooked peat in the mornin

In all fairness boiling roots had been something I have been wanting to do for years. There are multiple documented records of ancient cultures boiling mmj prior to using it to create medicines. The studies I read assumed the process of boiling the roots helped the plant cover THCa to THC and also aided the plant in the production of additional cannabinoids.

I haven't tried it. But I want to and we'd be silly to disregard everything different than what we've already done. Innovation comes from experimentation

Thanks @RM3 . You name be proud to be a born and raised Coloradan.

 

[Michael Huntherz]

To a point, I agree, but in this case I agree completely, there's not any data on this that I'm aware of. Have plant biologists tried this somewhere in the scientific literature, with Cannabis, specifically?

No man Hate to say it you boil your roots plants are dead there not going to do nothing or flood them with ice water makes no sense in ancient times they used to induce drought .
But make no mistake about potency although environment plays a small roll we must understand that
.
In general, the longer the life cycle of the plant, the more the concentration of cannabinoids increases, as long as the plant stays health and vigorous. Actually, it is the development of the plant, rather than chronological age, that determines this difference in potency. A plant that is more developed or more mature is generally more potent.

Because you decide when to plant and/or can control the photoperiod, you also control when the plants flowers and, hence, the overall age at maturity. A six-month-old plant will generally be better than a four-month-old plant, both of which are flowering. Plants eight months old will usually be more potent than six-month-old plants. Most indoor growers plan their gardens to be about five to eight months old at harvest. Healthy plants can be extended to about 10 months. Plants older than 10 months often develop abnormally. There is usually a decline in vigour and a loss in potency. But some growers have decorative plants several years old.

I think you have to grab the cob and cut away that silicone protective layer then you unleash the UV`s, lol

Actually had a cheapish "300w" led panel that`s really blue, I had that up in flower and one of my c99`s got a bit tall and as it was side lighting the plant got really close to the blue leds and that area of the plant went orange in a day or 2

So leds can make uv and blue rays for sure, just not a lot of lamps made to put out loads, a wee bit of uv seems to keep the mould down, as much as lamp companies talk about "cannabis leds" I don`t think many of them are actually research that much into it, just adding whatever amount of blue/uv will keep mould at bay, where as for people growing larger taller plants the blues and uv`s are great for penetration

Classic led growing was SOG lots of short plants and such, now cobs have come in people are growing 1.5m to 3m plants under leds and they want more blues back again, trouble is going for blues over reds will give you tighter stronger bud, but your gpw can go down, as that fluffy flower the red lights make can really add a lot of weight, also 3000k and 5000k cobs are easy to get but others seem to start costing more

Also I don`t think that its seen as very safe now to make a very bright very directional light that has eye burning levels of uv and blues, so maybe that`s why you have to cut off the silicone to get a cob to really pump out radiation ?

would love to see 1.5 m or 3m that is almost 10 feet lol grown with LED

Where'd you get your 48"T5 reptile bulbs

 

[THE KONASSURE]

I`ve got a 2m tent

my plants are pretty close to the lamps and no way the pots are over .5m so my plants are already 1m to 1.5m some of them get bent over, if I had more height I could do 2m or 3m plants no problem

been running some red/blue cobs for awhile now, they out penetrate a 600 hps for sure, 2 x 300w units with 4 chips there 100w`ish cobs being run at 70 to 80w each, but I`ve got all sorts of lights

main plus to hps seems to be that your plants drink more, I think that actually helps root growth and health but with the lower heat I can run more lights and cover them more and watering less means less work

So we can grow bigger plants in the same size pots yield more and do less work

And led growers are stupid ? lol

 

[2ANONYMOUS]

So with lower heat you sacrifice growth rates and here is 3 m plant there actually bigger then 3 m i am a 1000 watt De grower and have yet seen a 3 m grown indoor plant under Hid or led or cob one would have to run overhead lighting as well as vertical in any case cause YES even with a full canopy down 8 feet below the canopy no light including Cob , would make any grade A Bud side shot of plant this plant ended up being 10.5 feet tall and same wide

 

[ttystikk]

I do inoculate clones when roots show with trichoderma, but that is a one shot deal. You've argued synthetic hydro for several years and I have learned the wisdom of your advice after trying to culture various bennies in the reservoir and/or supplement with organics in hydro.

As for the LED/heat argument, the idea that heat MUST be wasted is false. The idea of exhausting through the top at a specific rate, or growing in an open area are parameters that can be changed. If there's excess waste heat it could be a system design problem. Less exhaust = higher temperatures, less energy devoted to heat management, less CO2 loss/use. The more efficient the light is the more efficient the whole system can be if designed correctly.

If there's any flaw with cobs it's that there could be a bit more 680nm without a corresponding drop in blue. 3500K with a bit more stretch between peaks would be ideal, but OTOH a 3500K cob generally hits around 40% relative power at 680nm so there should be plenty of light to drive the Emerson Effect, and the "peak" in the Mcree Curve is actually rather broad so there's no need to try and isolate 660. Perhaps at some point there will be horticultural cobs with competitive efficiencies, but I don't suspect a plant based spectrum will experience much increase in efficacy. They're pretty good already. Not many people are going high CRI to try and buff out their spectrum because they would rather have the umols. More efficiency is what is desirable.

I think the final word on cobs/diodes in general will be from those who use them and represent the growth in the industry from hobby scale to professional. It already makes sense for small scale growers to use LED, and with some creative design, necessary floor space as well as energy requirements will drop for large scale growers. I'm content to sit back and see what happens.

I'm doing the work now to scale up the promise of COB LED for larger facilities. I believe you will not have long to wait.
