Hellova increase i would say… i thought possibly higher but personally i think like co2 there will be a ceiling to benefits and that likely is above it

Hellova increase i would say… i thought possibly higher but personally i think like co2 there will be a ceiling to benefits and that likely is above it

Was wondering if he get its above 30, and im thinking the benefit falls off passed 40.

No clue.

 

[Observer]

You hit 36.7 mg/L?

Lmao

No clue.

From what I can find, seems anything above 40-50mg/L ,
MAY start becoming detrimental.

 

[moe.red]

30 was my expectation based on small scale bench test at my elevation and temp. Nice to see things match up

I think to drive it higher will require pressure or get closer to sea level.

I’m satisfied

Been thinking about co2.

I’ve been running 800ppm co2 during veg and 1200 during flower. Assuming that is tuned in for 100% o2 in the roots, I’m thinking 2400ppm or 800 x 300% co2 would be a fair starting point. Go up by the same proportion

So 2400 ppm co2 and 30mg/l dissolved oxygen. Thoughts?

Hmmm give me a day to ponder this… the math makes sense but there a few things i want to look at to see if anything may change the ratio increase being 1:1 or not.

I would say yes start there for now

[Aqua Man]

ok pondering done. 800ppm is 200% of atmospheric co2.

30mg/L is a 330% increase in o2

So to match you want about 330% Co2 increase which would be about 1325ppm co2

Does that make sense?

30mg/L is a 330% and increase in o2

Does that make sense?

8.5 to 30.5 is a 258.82% increase does that matter
Or am i doing something wrong

 

[Aqua Man]

8.5 to 30.5 is a 258.82% increase does that matter
Or I'm doing something wrong

His % increase was showing 330% in his specific conditions but yeah the math will change based on %

I just trying to convey the logic behind my thoughts.

Basically i think a good place to start is having equal increases by % for both co2 and o2. This would makes the most sense to me

 

[Aqua Man]

Now some studies have shown that a co2 increase to about 1200-1500 ppm to be the most beneficial which is 3-4times atmospheric.

I have a feeling that o2 will also fall along the same lines concentration wise.

 

[Aqua Man]

So yeah i don’t really have a definitive answer but i think with moes lab we may just get some answers

Ahh I see the logic

 

[Observer]

Thought: may expose other limiting factors.

Then we gotta "hack" those too.

Which has me thinking they will need a higher E.C?

But uptake IS more efficient.....but.....then starting a viscious cycle again.....

Dieing to see this In-action

With increased light, co2 and o2 transpiration rates will increase in coinciding amounts… thus nutrient uptake will increase at the same rate growth rates increase.

So nutrient uptake will passively increase as more nutrient solution will be moved through the plant.

Basically concentration of nutrients need not change because the volume of nutrient uptake has changed
