| There is no question that many different mixes are used to grow orchids and grow them successfully. If yours works for you , then by all means keep doing what you are doing. I am not opposed to coir (either kind), I just think the ground version is a risk due to water retention. The biggest problem with ground coir, peat and mixes using them is water retention in the root zone and the appearance of dryness on top (and sides). This is especially a problem in plastic pots.
Cynthia, I agree with untangling problem. I'm not advocating the use of either coir product. Coconut husk chips are sort of like bark and work well for my grower.
One thing has not been mentioned. Coir is nearly always salty and needs to be rinsed at least twice prior to use...and thoroughly rinsed. This can be a serious problem. Some suppliers claim their product is rinsed. I would not take their word for it.
One more important thing...mixing two very differently sized materials results in greatly reduced void volume. Just be aware of it.  |
