Higher temps = more water evaporation=more watering=more growth?

So you get double more weed then?

i dont know about that. maybe??? dont know
"
Results demonstrated that inflorescence yield responded quadratically to N and P, with the optimal concentrations predicted to be 194 and 59 mg L–1, respectively.
The optimal N supply for plants grown with liquid organic fertilisers seems to be higher, with the highest yields being achieved with an organic N supply of approximately 390 and 260 mg L–1 for the vegetative and flowering stages, respectively (Caplan et al., 2017a,b).
These studies indicate the optimal N supply for both vegetative and flowering stages of cannabis production using conventional fertilisers is approximately 160 mg L–1 (Saloner and Bernstein, 2021).

That study has nothing to do with hydro vs organic yields.

CO2 is likely going to be your limiting factor. If you add CO2 your plants can photosynthesize more, and also take higher temps and EC. The yield increase can be significant.

The CO2 concentration directly affects stomatal opening. Which controls how much vapour leaves the plant and how much CO2 enters the plant. When running CO2 it's important to have fans churning up the boundary layer. So the leafs always see the higher concentration of CO2 as they will deplete the atmosphere directly surrounding the leaves.

Talk about taking things out of context, right?
The study references other peer reviewed studies with conventional fertilizer and the optimal amount of N using it.
They found in this study the optimal amount of N using liquid organic fertilizer to be higher.
It doesn't say one is better than the other, rather liquid organic fertilizer required higher amounts of N to reach optimal levels. It doesn't make mention of inflorescence yield comparing the two types of fertilizers.
I know you understand this @PJ Diaz but @amneziaHaze has no clue.

Exactly. If anything, that side note which implies that organic is less efficient compared the DWC, an outcome which no one should be surprised by.
What lol that study has nothing to do with organics its just testing different nutrient levels in DWC.

Agreed!
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8635921/ is a worthwhile read comparing NPK levels
If nothing else, it shows again that raising P dramatically is unnecessary

I dont think i said better i said she eats more organics.does the reaserch say she grows better? Did i sad she does or did i say maybe i dont know? People dont know how to read anymore.
Reassrch said optimal in organics ia more than in mineral.
Dude allsoo asked if he will get more yeald if he waters more.it depends hoe much nutes he puts in if he was optimal then he will get more ifhe was too much he will stack it and overfeed.if he uses only water it will wash away parts.soo 8f he was.or than optimal maybe he will save it.its all guessing in soil

Well the original question was does more inputs equal more growth. I thought that was what you were trying to imply. If you weren't what was the point in even making the reference to the study and the difference between normal fertilizer and organic?

Because
Maybe i had an idea that organic gives better results since she eats double no idea but i wrote at the beggining that i am not sure and told you about the link on my status soo you can check it out alone and decide
Because the study allsoo says that plant will grow better with more but not with a lot more even thou she will not show signs of problems.i was high yesterday those numbers where fresh in my mind no idea what i was planing with them. I mix stuff often...

The study doesn't show that organics "eat more". If anything it shows that they need more nutes in the soil to have the same amount of uptake to the plant, therefore it eats less.

okej soo organics consume more nutrients soo they eat less. i guess i was mistaken
PJ Diaz

It doesn't say that they are consuming more, it says that they need more in the medium. The reason is because soil grows are less efficient than DWC.
