Test Your Coir with Corn Seeds

aruzinsky · 03-11-2022, 02:32 PM

I was inspired to test coir by this paper:

https://digitalcommons.usu.edu/cpl_hydroponics/1/

I planted corn and tomato seed in the following peat moss - perlite mix:

1. https://www.sungro.com/retail-product/sunshine-mix-4/

and 50% mix with perlite of the following 3 brands of coir:

2. https://www.amazon.com/Coco-Bliss-Pr.../dp/B06W9F7XDY

3. https://www.amazon.com/gp/product/B0...asin_title_s00

4. https://www.homedepot.com/p/Vermont-...11LB/300679904

All plants were treated the same and fertilized with a complete hydroponic fertilizer. There wasn't much difference for the tomato but look at the corn, left to right, 1, 2, 3, 4, respectively:

You can see one tomato plant because the stem took root in a pot of corn, ha, ha! I suspect that corn is sensitive to sodium toxicity. My point is you are taking a chance using coir by not knowing exactly which plants will be unfavorably influenced. You should perform a test like this for every type of plant that you pot in coir. Or, just use peat moss based mixes.

Great info. What kind of hydroponic fertilizer did you use?

Further testing indicates that banana plants grow well is straight coir. Also, tomato seeds germinate sooner in coir than in peat moss, although, after germination, growth is about the same. Therefore I am going to try germinating some musa and ensete seeds in coir.

Here is an interesting article I found some time back on banana seed germination. Didn't have enough seeds to try to replicate.

Thanks. Based on this, I will soak my musa and ensete seeds in 0.1 % KNO3 solution before planting in coir.

Vermicompost and soil are too variable to be reliably replicated in an experiment. It's no wonder that the results of published experiments in the life sciences are often impossible to duplicate. In comparison, the results of experiments in mathematical sciences, such as physics, chemistry and electrical engineering, are easy to duplicate.

Any update on the seed germination experiment?

No, that's all there is.

I am using coir for tomato, musa and heliconia just fine. There is no need to test coir for these plants.
