I am making a bath tub size batch of potting mix. I will be substituting coconut coir for peat. Today I bought a 50 lb sack of coir for 500 prsos ($9). I am retired and live in the Dominican Republic.

I’m finding most of the ingredients for free in vacant lots and building sites close to where I live.

Would you like a report on what I’m doing? Photos?

In reply to Kenna. I honestly just eyeball it, but a measuring cup is preferable to weighing it.

Hi there!
I found this very helpful! O have a question.
Should I measure it out with a measuring cup for all parts or should I measure it out by weight? I know that could make a big difference if it’s 5 cups of this and 4 cups of this vs 5 pounds of this and 4 pounds of this.

There is absolutely a reason acidity /alkalinity is measured on a pH scale. pH stands for the inverse log concentration of hydrogen ions in an aqueous solution. Acidic compounds are acidic as when in solution they increase the concentration of hydrogen ions (H+) compared to hydroxl ions (OH-) compared to an equally balanced pure water solution (H2O), I. E. Sulphuric acid (H2SO4) dissolves into 2 x H+ and 1 x SO4^2- thus increasing the relative concentration of hydrogen ions in a solution and causing a lowering in the inverse log (pH).

After an extensive search for a peat-free mix, I finally came across Organic Mechanics. They have a few different blends but I am using their regular coir-based potting mix and adding ingredients as needed for certain plants. So far, so good. If you can find it in your area (their website has a search function for retailers), you should give it a try.

The roots looked reasonable to be honest, there was maybe a centimetre of one that i trimmed to be on the safe side but it wasnt mushy. ill keep an eye on it over the next day and if it looks to be deteriorating ill follow you recommendation. Thank you so much, really appreciate it
