The use of coconut fiber as a growing media for tomato has been investigated. Teo and Tan (1993) found that a mixture of
coconut fiber and charcoal dust (2:1; v:v) produced the greatest
plant height, number of fruit, total fruit weight per plant and the
largest mean weight and fruit diameter. The purpose of this study
was to investigate the use of Scotts coconut coir media as an
alternative to peat for both tomato and pepper transplants and to
follow the growth and development of those transplants in the field
through harvest.

Does someone know how to treat the coco coir to use to grow?

I mean where i live there ain't no shop selling coco coir but thousands of coco tree but I don't know how to transform it.
I've tried to make a search on google but didn't find any good informations .

I wouldn't even bother trying to convert natural coconut fiber to coco coir to use as a growing medium. You'll never be able to treat it like the coco companies do to get the salt out. Sorry dude.

Yes, it seems to be a lot of work for a small amount of fiber , only way would be to buy it from a company who is working with coco fibers , but i don't think we have that type of factory in french guina, maybe i could find from Suriname wich is very close or in Brasil.

Concerning the salt , i think it's a problem occuring wit coco trees which are planted near te sea, where the water and ground have salt.

I can find some coco from area without any salt, and anyway the process request to leave the coco hush in a pit full of water for ten month, to soften it.
But i don't know the whole process and it seems to be too much work for the benefit.

Sodium occurs naturally in soil. While it is true the salt concentrations in coco trees that are near salt water is higher, salt still shows up in the coconut hulls and fibers of those trees located farther inland. The coco tree is unique in that all salt it needs to rid itself of is sent to the hull and fibers of the fruit.

You're right. It won't be worth your time and effort to try to make do with what you've got growing around you.

I finally found a cocopeat supplier from a coconut fiber factory in Suriname, but i will have to test it to see if it's good for growing mj . Will make a test with a bagseed from local strains before i go for the precious seeds.

For those who are intrested in producing their own cocopeat ,i've found this cocopeat machine supplier : https://www.toboc.com/3/4795/Exporter.aspx

The machines are expansive and it's for an industrial purpose or if you need tons of cocopeat !

Any interesting articles found lately?

This link is to a dutch growshop, that offer growguides for download in PDF-format.

I like their coco guides (both for slabs and pots) and there are several good tips on how to maintain stable pH/EC throughout the bloom period and such...

Dutch, english and french versions available for coco growing.

What instrument or chemical could be used to test the salt content of coco fiber? I have been soaking about 12 cu ft (200 lbs) of local coco - $ 4.00 LOL -
for 10 days and am interested in seeing if any sodium remains before I use some in a test batch.
