COCO COIR Coco question

[Iammygod]

● Yes. 0.7L
● 50-75% is what i had found in web before. I've never measured PUW of my own coco but i know water availability effects nutrient availability. So i water before the weight of the pot reach 60% in veg when plants are big enough and 75% in the heavy flowering. We may find some data at medteknutrients.com.au. I'll check later for you if you request.

● Cations in the solution, not just initially, but always and always exchange with CEC sites back and forth. The exchange rate decreases as exchange progresses. So we need time to reach equilibrium. We are talking about buffering, Why do we have to ask about water potential?

● 100g dry coco absorbs 700g(0.7L) water to reach 1.4L hydrated coco with Reletive density of 0.57. I found no error.

●

● Lost and gained

● Too complex to find a formula. Yes, Temperature and concentration effect rete. And time requirement depends on rate.

● Yes; 400PPM. We all here to ask and learn.

Ah yes yes. Thanks again, this was very helpful. In the future i may poke your brain again but for the time being this has been plenty.

The water turns brown very quickly and a fine dust goes tru the fabric and ends up in the bucket. I can only assume all kinds of things are being flushed. I don’t know where the coco came from. But I know I will dump the finest dust that sank to the bottom and use only the top 4/5ths of quality fiber. When I rinse. Should I flush until the runoff is not dark brown??

Yes flushing the finer particles of coco peat is beneficial, so flushing until clear (indicating that most of the peat that can be leached has done so) is good. I think you will have satisfied the coco enough after what you have done

After 24 hours soaking I rinsed like campesino suggests in his video with a metal pasta strainer and removed all peat, I left the coco soaking one last night. I figured I can’t over do it right?? Thanks a lot dan, have a wonderful Sunday. I’ll keep you posted

 

[DrPhoton]

Yea exactly. You too man, ima watch the boxing soon ^.^ go wilder.

 

[9fingerleafs]

A little update. Popped 5 seeds and placed in solo cup with coco

 

[9fingerleafs]

Update, seedlings looking a little light but very healthy

 

[DrPhoton]

Nice, did you decide not to use any perlite in the end ?

 

[9fingerleafs]

No. I will use perlite, I just needed to transplant and the perlite wasn’t here. I’ll add it in the next transplant

 

[DrPhoton]

Cool cool. Theres so many types of coco isnt there. Mine is a much finer grade compared to yours. Yours is very stringy/barky. But im sure its fine.

 

[9fingerleafs]

Yeah maybe a rinsed too much, I chose the 70% peat and 30% fiber but after all that soaking and rinsing only fibers remain, I’ll have to do a side by side in the future with the peat and without it

 

[DrPhoton]

Yea that would be interesting to see.

 

[9fingerleafs]

Just a little update, transplanted 5 seedlings into one quart containers and he first 3 clones went into solo cups with coco as well. I also added the perlite

 

[9fingerleafs]

3 of the seedlings looking fantastic, one not so much, and the little tint on the bottom

 

[9fingerleafs]

A little update on those seedlings. Still in one quart containers, seems like they’ve developed lots of roots and started taking nutrients, color is better also, getting darker every day

 

[9fingerleafs]

These are being grown next to the window, and 14watt cfl at night

 

[9fingerleafs]

ANother update, this is day 19 I think, roots are growing fast

 

[9fingerleafs]

Also I top/fimmed

 

[DrPhoton]

Nice, they looking very healthy.

 

[9fingerleafs]

It’s day 22 for the seedlings, two of them are ready for transplant. I made medium size bags out of black garden fabric. I think between 2-3 gallons
