Soil mix experiment
Hey all, after reading this forum for ages, and learning all I can, I decided to run a little experiment this year comparing various plants growing in different soil mixes.
I especially got interested after a debate in one of my first posts regarding coconut husk chips vs pine bark fines.
I have 3 okra plants one growing in 5-1-1, one in plain potting mix and one in a mix made mostly of coconut husk chips. I then have 3 Fatalii Chillis again growing in 5-1-1, plain potting mix and coconut husk chips. Finally 3 banana chillis once again in 5-11, plain potting mix and coconut husk chips.
After a long delay of 7 weeks after transplanting I finally got down to measuring and looking at the differences, and have found some interesting and mixed results.
The experiment will run until our first frosts knocks everything dead in April or so, so these results may change over time, especially since it looks like we are in for a really hot summer!
The chart below shows the percentage change in growth of each plant in each mix, measured 1 week after transplanting into their mixes, and today, 7 weeks after initial transplant.
Its worth noting that a particularly cold morning which got down to 2o C totally stopped one okra dead in its tracks, and although it still lives, it has done nothing since then, hence 0% growth.
