These are my methods for improving the chemical and physical properties of soilless medium .
Instead buying new medium every year or two you can follow these steps and make your ideal soilless medium … those are my preferences , you can always change it , but if you complete those 8 things there is no need for buying new one .
| My soilles mix | Set tartget | Increase | Decrease | |
|---|---|---|---|---|
| Fertilizer charge/CEC | Constant liquid feeding (CLF) | <1500 ppm | Fertigate | Flushing |
| PH value | CLF with Calcium Nitrate | 5.5 - 6.5 PH | Liming | Sulfur compounds |
| Wettability | AquaGro2000M ; Yucca | < 5 seconds | Wetting agent | Decomposition of organic materials |
| Total porosity | Coco Coir/Peat Moss/Perlite - 82% | 75-85% | Coco, Peat Moss, Perlite | Compaction , higher bulk density |
| Container Capacity ( Water porosity ) | Coco Coir/Peat Moss/Perlite - 50% | 45-50 % | Peat Moss , Coco Coir | Perlite |
| Air space ( Air porosity ) | Coco Coir/Peat Moss/Perlite - 32% | 30-35% | Perlite | Coco Coir,Peat Moss |
| Bulk density | 0.09 g/cm3 | 0.08-0.12 g/cm3 | Pumice,Sand | Coco Coir ,Peat Moss , Perlite |
| CFU pathogens | Flush with Sanidate 12 , introducing RAW grow microbes 48H after Sanidate 12 | N/A | N/A | Sanitize and bacteria introduce |
