Civility people, let's keep it civil.

As for my comment on my plants taking more.

I was running a well used clone under my migro cob.

This girl would burn at 1.4 of organic bottle. When the led came on the scene she took 1.8 no problem. I didn't push past this though.

For clarification.

Its normal plants with Leds have slower metabolism and often growed in lower temp lower water evaporation,so they can handle more nutes.
Nothing new in my expirience.

Plants generally take up nutrients through their roots, and this process often occurs in the presence of water. Water helps dissolve and transport nutrients from the soil to the plant's roots. Nutrients are usually absorbed by plant roots as part of a water solution. So, while some nutrients may be present in the soil, they are more effectively taken up by the plant when water is available to facilitate their uptake.

Imagine leaf surface,room temp,substrate temp...they all play role in metabolic rate.
One thing what you get with hps cuz IR react with water molecules in leafs and leafs have higher leaf temp than room and plants very much love that.

Anyway what are your temps in room/box ?
i am not trying to argue with you, i'm trying to help you.

right now, i'm in a leaky old house while i build a house close by so i can't run co2 like i usually do.

because i'm not using co2 i run the room at about 81-82f . the leaf temperature using an infrared thermometer is typically about 80f.

light is 1200 umols ppfd for 12 hours using a quantum meter to measure par. giving a DLI of approximately 51.84 mols per period.

part of this light is coming from 150 watts of incandescent over each plant.

my recirculating solution is 78f, with an ec of about 1.6 and ph at 6.2.

the system is tightly sealed to control evaporative loss.

here is a pic of the way my system is built. i normally use buckets for the bottom container but since i'm renting someone else's house i use kiddie pools so that there is no chance of a leak.

i've included 3 pics for you. the first is right after transplant into the system and it shows the only points i get any evaporative loss in the entire system. the 2 8" holes in the reflectix that are around the plants.

the second is just a flower shot at the end of 6 weeks of flower. and then the whole plant at the end of 6 weeks also. this is a 10 week strain.

Its all grown under Leds.
Show us your grows mate theory and practice are very different.
I smell that agenda in you you are here just marketing troll.
Marketing for who?

If you just put up pics, people are going to think they are yours. If they are, then you have a rot problem. Them pics are of bad plants, not bad lighting.

I won't say it a 3rd time. . I'm telling you there is rot in them pics, because there is rot in them pics. I have no interest in sabotaging you, you are nobody to me. Yes you are feeling under attack, like it's you against everyone else. Stop the fighting though, and think about what that might mean. One person against the progress of everyone else. Are we really all wrong. The whole industry. Or might your rotten plants be the cause of your poor outcome.

Wake up man. The odds are more than stacked here.

Im not arguing on anyone I just share my expiriences,some feel ofended by my statements and they start to punch under the belt.
Im all for discussion always.
I dont say anything cuz Im also Led grower I just share my opinion I get from my expiriences.

It will be stupid to say Led cant produce fire buds.
I take advices sometimes and talk with growers that I consider way better growers than me and they are switched to Leds.
They have higher G/W very tasty stuff fregnant and potent.Who cares about SC and alchocols.
That is just my preference I like weed with higer amount of SC and Alchocols.
New Candy strains have better taste grown under leds sometimes its so tasty that you need smoke just for the taste.

Im not black and white.
Our purpose dictate what is good or what is bad.
There is no universal good or better,bad or worst.
Everything on earth have its purpose.

If you judge fish by ability to climb a tree it will be useless.

@exoticrobotic Pics of my plants, wouldn't help his rot. Nor add to an LED discussion, if they were today's plants. I'm using LED as auxiliary lighting.
I know a lot of people are quick to search years of albums, to find their best pics to post every week. While just as many will cede when some off topic pics are produced. It's just my ego that would benefit from that though.

Edit: Removed irrelevant pics. It was breaking the focus of conversation.

This thread is painful to read with the amount of ignorance in here mostly based off 0 self experience . I spent 4 years running two facilities one with hps one with led. Done same strains in both about 80 runs of side by sides and led always won in quality and very close to yield , so much so I only run leds now

Anyone saying leds grow trash or worse than hps you don’t know how to grow with leds and have done 0 side by sides and just repeating what others say

What people don’t understand is the places you get flower from to form your led is trash opinion are mass production facilities , that wouldn’t put out good flower regardless of what light they use . There flower was trash with hps too. Because mass production makes shit flower not lights

Imo people hating on leds is just how people cope and justify the fact that they are paying twice as much to grow the same flower

And imo Athena grown flower has more to do with the amount of bad flower out there than leds do. Because I’ve used it and can confirm it grows trash flower. Many using leds are blindly using Athena at 3 EC

Learn how to grow flower properly with proper nutrition and the lights won’t make as much of a difference as you think , but hey I’d be lying to myself too if my power bill was double what it is now for no reason other than my ignorance and lack of skill
Regarding side by sides.

I add this quote as DJM is another high level grower on par with @greyfader & @Crooked8.

They would certainly help, all photos of plants along with light/feed/humidity/temperature other conditions help us all. I dont read @CannaT comments as rot at all. Just posting experience.

I find it rather difficult and frankly weird people taking negative comments on leds and plant morphology so personally, especially with so many different brands, set ups, and spectrum mixes.

We all wish to learn how to grow in the best way. I personally had issues with the maxibright leds and found them utter shite. That's not to say all leds are shite.

Posting pics with grow conditions and lights used allows us all to make better informed decisions with our growing witout spending the 1000's trying different light units.

It is plain to see some led units grow plants with less visible issues than others.

It is plain to see some leds grow 🔥

It is also plain to see some leds are not growing great plants.

I know a lot of people are quick to search years of albums, to find their best pics to post every week. While just as many will cede when some off topic pics are produced. It's just my ego that would benefit from that though.

Again, i disagree. I try to document my grow to help others and myself so i can remember wtf i've done and its effect on the plants so i and others can hopefully learn a bit to fine tune growing.

Does that satisfy your curiosity?

No, it's a bud pic, not plant pic.

No, he's not talking rot, he has rot. Signs on the leaves, stems and buds.
There is no point looking at my pics, look at his. The roots have gone.

My pics are just a distraction.. I will remove them. Try and keep the focus on what matters.

You like pics for reasons that are not important here, but don't want some bud pics that people are wishing they had seen. That about sum it up?

You can't hear me saying, repeatedly, that his LED plants were bad because they had root rot. That is the issue here. If you have another, let me know, as I can't see it.

Personally i'd like pics with all comments so we can all help each other but the very nature of Cannabis i know means that is unlikely.

And that is where a photo is so valuable. The ability for us all to diagnose things so they are not mistaken for other causative agents.

Lesson learned....Led grown plants may stay wet and cold longer.

So next time we slightly heat the pot or insulate it or put more perlite in for drainage.

And we dont see that issue again...

See?

You cant have it all @Ca++

You chastise others for making comments on leds you regard as opinion with insufficient evidence to back it up yet you refuse to post photos of your plants to back up your led prof persona.

What gives?

if you guys actually read what Ca++ contributes you wouldn't even feel like he's chastising anyone, y'all cant seem to be able to read and add

We need to differentiate between evapotranspiration and metabolism, because it's not that when leaves loose more water the plant grows better. Most of the water is used for cooling and C3 doesn't like it too hot, because then plant will increasingly use oxygen as the substrate for photosynthesis, instead of carbon dioxide, leading to increased photorespiration and loss of carbon instead of gain. Still, the enzymatic biochemical reactions inside a plant benefit from warmth, but all that doesn't help when the biggest building block - carbon - is missing or not at optimum levels. Because of this there exists an almost linear relationship with the acquisition of biomatter and the rate of photosynthesis done.

Diodes now put out more PAR than HPS, while HPS puts out way more heat radiation. Make no mistake the 730nm spec hump you see in many LED racks is not there to deliver heat into leaves, as such 1500nm or 2500nm would be much more appropriate. The 730nm light mostly transmits plant leaves but is sensed, and weighted, by the phytochrome photoreceptor family and a few rare darkred di- & trimeric chlorophyll-groups around the core of photosystem I and one antenna of photosystem II. The radiation between 700 - 780nm has actually a unique quality whenever it is absorbed by chlorophyll it can still power photochemical work just as PAR - even though it lacks the minimum energy requirement - said energy will be taken from the latent heat locale at that side, that is, and has been measured quite accurately, Far Red can have a tiny photoprotective role whereas other IR can still help deliver this locale latent energy much better than convective.

Water-use-efficiency is just better under LED, they still drink as photosynthesis itself opens stomatas up, that's better than if mostly for cooling. If leaves get too hot stomatas even close in an evolutionairy coded attempt to preserve more water during periods of long hot- and dryness.
