Buds quality LEDs VS HPS

[ANC]

I can't fit anything I do in that space and it would prove nothing to me. I am not arguing about the ability of cobs to grow. I am arguing they are not better and that the tech we are discussing isn't even the kind of led that will be the standard.

I use air cooled hoods in my little room. I don't have a heat problem. I designed the room not to.

They don't have to be better, just pretty close. We would spend a further 1.2kw on top of the 4kw COBS we run doing nearly the same output with other tech.
Make little difference on a micro grow, but once you start getting a few lights up, numbers add quickly.

Nug size is of little importance unless you're worried about bag appeal. Total weight and quality are what matter.

New led lamps are not blurple anymore. They use white, green and ir and uv diodes even. But they are $1500 and up.

And where I live I save up to $800 dollars of heating propane per year using hid exhaust to supplementally heat my home.

The air conditioning is shared between 2 rooms and is only an 8000 btu window unit I need on anyway in summer.

I would have to heat the flower room and lose the savings if I go led.

I realize it's extra work and initial expense, but why not swap your lighting for hot/cold seasons?
That's what I'm thinking about doing.
Like you, I need the heat in my grow space during colder months and during the summer I grow outdoors. Spending zero on electricity for my herbs is awesome, but the quality of outdoor bud is never as good. So why not run two crops during the summer? One crop inside with quantum boards or COBs, and one crop outside? Hmm...

Educated growers don't need to argue any of this. We need to read about plant science is all.



But my 600's are already higher than 1000 PPFD no?

600w HPS provides around 1100 PPF. 1100 / 16 * 10.7 = 735 PPFD in a 4x4 tent. You need a 1000w SE in a 4x4 to achieve 1000 PPFD.

oh didn't see that, might be able to come close then with 2 of them, doubt the size of the nugs would be close tho.

I am not trying to have a 1 sided argument. I am sure they are putting down more usable light per watt than hps.

 

[MichiganMedGrower]

Ok then carry on... I'm offering a case scenario that can easily be vetted by peers and scale up.. it works
Air cooled hoods and HPS can't do what we can with LEDs, you'd be such a better designer with better tools imo but i respect your archaic choices as well afterall i rocked HIDs for years.

I'm just still using what I started with. I'm interested in the tech and learning. LED's were quite expensive when I set up my room.

And I disagree about the cobs being better. I have not seen real proof of that. If anything the uv present and the ir mimicking the sun in hps is better for our plants flowers.

I'm running 2 600 DE's now, will switch to CMH/LED in summer.

At my size power bill there would be no point. It wouldn't make enough difference.

I spend about $120 per month on Grow electricity and produce "about a pound" per month perpetually.

And I don't want more work.

wait what? my outdoor always comes out stupid fire, nothing like the sun....

I've been thinking of also maybe trying LED next summer. Not sold on the idea yet. Might just grow some kick ass bud next summer with a single 400 W HPS.

You haven't seen but have you ran modern LEDs even one time?

We can assume your lack of "seeing proof" stems from your inability to try for yourself? Hence why I offer the 1ft² trial run, try it one time then come back and let's discuss.

Having ran large HID rooms I can offer you my opinion in that I feel the exact opposite of what you offer, only my opinion has a bit of credibility as I've tried all of these things.

LEDs are still expensive, i'll give you that much.

Never seen so much wasted energy fighting against something, you would think it was maybe child abuse or cancer but no the cause is railing against LED, wow about covers it.

I see. I mixed up the terms. How much does 3.5' x 3.5' area change that number and how are you accounting for lamp height.

The 600 has the same intensity as 1000 at about 16" over the canopy. Just less area covered.

I think you are over minimizing the hps usable light.

It depends on where you live. Here in the Pacific NW, plants don't finish as well because of the changing weather.
Later in flower, I also had to move them under a shelter every time it rained in an effort to prevent bud rot, but I lost a few ounces. Still worth the effort though.

I pulled about 30 zips total.

Seems you have it backwards. The led crowd is putting forth all the energy. We just screw a lightbulb in and get to work still. Lol.

The current available lamps shown here and the constant changes in light temp and even types shows a product in its infant stages.

 

[captainmorgan]

You guys do know that HID will probably go the way of incandescent bulbs and be banned at some point because it's a inefficient obsolete tech.

More likely to be banned because of fire hazard issues, some counties here already have it banned unless you get inspected by the fire department.

Buds under (good) LEDs are so good compared to HPS, weed under HPS is very "stereotyped"... it's more difficult to feel the real and deep differences between two strains or two phenotypes of the same strain: with LED you just need more curing because of the density of the buds that are not sponge like the HPS buds.. I use 4 x4 CREE cobs at 1750mA in my 150x150cm, I harvest in soil 1.4kg sometimes a little bit more or a little bit less depending on the strain.. I won't never go back to HPS, it's not serious if I did it!

 

[CannaBruh]

I haven't had to screw in a replacement LED yet (knock on wood)
How is replacing lamps every year treating you?
I've sent LED buds to the people who shared these cuts with me years ago and I have records of their reactions and impressions and not a one had a negative thing to say about the LED grown as they didn't even know it was LED buds...

I challenge any HID maximalist to an HID/LED smokeout and we can record the whole thing for youtube.

Can you show us your sponge like hps buds and then show us your Cree cob buds?
Thanks for sticking with the Cree INC brand though!!!!!!!! Keep up the good work!!!!!
