Truly soilless medium?
50 / 50 vermiculite / perlite mix, no soil, no peat, no compost.
Excellent water handling characteristics, pH would remain dead stable. No pests, no disease. Feed with organic tea to replace the missing OM portion. Would this work as well as a good standard potting mix such as Pro Mix? |

I have tried mixes with 33 percent perlite and even with a lot of compose tea they did not work well. Also, too much perlite (over 25 percent IMO) tends to become "messy". There are many good commercial mixes (without soil) that work much better. Also, it might help if you tell us what you want to grow. Some mixes work better than others depending on the plant. -- Bill R.

I have tried mixes with 33 percent perlite and even with a lot of compose tea they did not work well. What type tea? I have an endless supply of activated worm tea, enough that most of it goes down the drain because of 3 day shelf life. Can't think of anything richer, pure organic rocket fuel, puts even Miracle Gro to shame. Also, too much perlite (over 25 percent IMO) tends to become "messy". Drainage agent, first one that comes to mind. There are others that could be used, maybe coarse sand. I know perlite can float and separate if flooded. There are many good commercial mixes (without soil) that work much better. Also, it might help if you tell us what you want to grow. Tomatoes, peppers, zinnias, lettuce, everything. Some mixes work better than others depending on the plant. Straight perlite and vermiculite is as dead and neutral as it gets. Should work with anything that likes well- drained soil, depending on the nutrients and pH of the tea. |
