Led quality and yield vs hps?

This is gonna be an ongoing debate forever. My personal opinion from research not from experience. The larger grows it seems like MH/HPS will blow led out, but I've seen some small grows that LED will top.
But who knows lol, depends on grower, set up, etc. every situation is different!!! I switched from mh/hps to LED, haven't compared full grows though.

My opinion, a led company that claims lumens are important for a grow, should stop making leds immediately.
It's all about PAR and reaching the best ratios within less possible electricity consumption.
Only a few companies research this and they can value their products quite highly. The market reflects that, resellers like Lush are a majority as there is still lots money to be made with this approach.

I'm going to be making a journal. I'm flowering in a 5x9 tent with 10 100 watt xte lights. It's really about how much money you have to invest. Smaller lights spread out is the key instead of one high watt unit.

4 of these lights fit in a 4x4 tent perfect

Waterlab- how do you run your nutes, I heard you should cut your ppm in half.

Right now she's ar 1200ppm. I'm using AN two part perfect ph. But I only run then 3/4
Honestly I've only added nutes twice this whole time, gonna flush a week into flower and then add bloom nutes. And some other things.

No. Who is claiming that LED's are better? Lush led, who happens to sell LED's...
The last LED seller on ICMAG who claimed LEDs were better got tons of people to by his/hers systems and they fucking sucked. She/he had a hell of a following until the claims were shot down and she/he ripped people off...
Lush led should pay an independent company to verify their results. Until they do, I wouldn't believe anything they claim...

In no way shape or form do I know anything about lush. I was just stating from the company i purchased from. Not trying to sell anyone's product lol
like mentioned the closer you can get to providing the PAR at the correct intensity emitted by the sun, the better it will be. if you can do that with LED or HID matters not, just personal preference really. these plants evolved over hundreds of thousands of years under our sun, it would do anyone justice to attempt to imitate that as close as possible.
show me one peer reviewed study that can conclusively point out exactly what wavelength of radiation is needed and at what intensity, to produce each individual terpene or any particular terpene. you wont find it because it doesn't exist, so we would all be wise to stick with what we know. and that's full spectrum lighting at the proper PAR intensity's. not just this or that wavelength of red or blue.
i currently do not subscribe to the theory that LED can perform better than HID PAR for PAR and how could it when the same intensity of PAR equals the same intensity of PAR, source matters not.
can one produce the same intensity of PAR watts in a full spectrum setting with LED (cheaper) verses HID, i currently doubt it, i think if one did some experimenting they would find they both use fairly the same amount of energy to produce usable light and also give off about the same amount of heat.
i had a 200 watt LED running in my room that had my ventilation running just as often as a 175 watt MH lamp, i had noted years ago.

That why I'm investing in LEDs, I'll prove they can do better and I'll post it. I totally disagree with people saying they give off same amount of heat (maybe the cheap Chinese panels do)I'm running 400 watt of led and there was a 1 degree difference in room temperature with my inline fan on the lowest setting. What people are not doing right is spreading the light over many multiple fixtures.

Is there life issues with them? Can the lights be replaced? I've thought about using them in my clone and veg room. What I saw at the shop was not impressive in terms of foot print for the watts that were used.
I feel like they would be much more effective if the fixtures I've seen were the same size as the footprint.

they require circuits and fans so yes, there will inevitably be hardware failures and also diode failures as well, but no more then any other artificial light source i wouldn't think.

LED lights last much longer...imo. If you have a basic knowledge they are very easy to make your own panel. Much more cost effective. And can achieve the light spectrum to fit your needs.

led technology isnt up standard imo. But i will say that i had some mommys under a led and she was full of multiple nodes, on each branch But not much height.
stick with HID's

Like i said...never ending debate lol.
I have a little grow box I made. Inside are cfl's,t5's and a cheapo led fixture off ebay from China. The led fixture itself is about 12"x12" and it has 60, 3 watt diodes. The plant that is directly under the led always does exceptionally well, as do any branches that stray into its light path. There's no co2 in my box, I just move lots of air thru it. The buds under the led are always the densest, and the plants don't stretch as much as normal or as much as the other plants in the box. These are observations I have made over multiple runs in this set-up with no changes.
I love my little led as I feel it is great complimentary light. I'm seriously considering buying a larger model so all the buds in the box are hard as rocks. I still love my hids in my big room.....don't get me wrong. I just tried an led to see what was up.....and I ended up loving it.....
