Aloha,
For me coco coir has been a true humbling ride. I found the 1st thing
I should have done was wash it. I found that G.H. has florakleen. It's a liquid flush for hydro users. Flush, rinse, repeat... I let it dry for a week and fluffed it up and off I went . In hind site, I could have gave it more time to dry. But I couldn't wait.
The deal is that salts or saline buildup in the coco, creates problems with uptake of nutrients to my plants. Once I did the flush this grow has been a huge difference.
The coir that I have is almost 3 yrs old. I just kept replanting , my bad. I should also tell you that I use hydroton (clay pebbles) and perlite. And due to many factors like weather, humidity , heat.etc.. some of my planting ideas do not work for Hawaii. But as far as coco coir I am a true believer. It is a great medium to use in containers.
Aloha and good luck.
Tom
