-===== Calculate water saturation ===== 
-Possibilities of substrates are endless. To determine the expansion and absorption capacity of a new substrate, you can use the method below. For obvious reasons, it is clever to automate these calculations.\\  
-<tab> 
- 
-**Take a sample of 100ml of dry substrate and weigh it**\\  
-<tab>100ml sec = __50__g 
- 
-**By soaking or cooking, saturate the substrate with water. Let drain 15 minutes and measure the new volume**\\  
-<tab>100ml sec = __200__ml wet 
- 
-<tab>Expansion ratio = Wet volume ÷ Dry volume\\  
-<tab>__200__/100 = __2__ 
- 
-**Weigh the wet sample, and determine the amount of water**\\  
-<tab>__50__g dry = __125__g wet 
- 
-<tab>Volume of water absorbed (per 100ml) = Wet weight - Dry weight \\  
-<tab>__125__ - __50__ = __75__g = __75__ml[(:hidden:>For water, the units of weight and volume are interchangeable)] 
- 
-<tab>**Conversion for 1 liter of dry substrate**\\  
-<tab>__75__ml water / 0.1L dry = __750__ml / L dry 
- 
-<WRAP left box 60%> 
-**Calculate the amount of substrate necessary **\\  
-<tab>X = Number of one-liter pots\\  
-<tab>Substrate need = (X ÷ Expansion ratio) * 70%[(:hidden:>Allow 30% of free space to break the mycelium afterwards)]\\  
-<tab>Substrate need = (X/__2__) * 0.70 
- 
-**Calculate the water requirement**\\  
-<tab>Water need = Water absorption (per liter) * Volume of substrate moistened\\  
-<tab>Water need = __750__ *((X/__2__) * 0.70)
