We recommend a substrate volume of between 7 and 9 litres per square meter of the cropped area of the glasshouse.
This volume is very important because:
So it is important that the substrate volume you choose matches the capacity of your irrigation system, accuracy of your drippers and your objectives. This is why we developed the Substrate Calculator. Please consult your local Cultilene advisor if you want more information on this.
The volume of a slab can be easily calculated by multiplying its length by the width and the height (in cm) then divide by 1000.
For example a slab = 100 x 20 x 7.5 cm /1000 = 15 litres.
We normally measure the amount of substrate by the number of litres per square metre and this is can be calculated using our Substrate Calculator or manually
For example – Cucumbers
