The economics of the stationary vertical indoor farm were calculated with the following input parameters (Electricity price 2.0 CZK/kWh; Water price 80 CZK/m3; Operator labour price 160 CZK/hour)

Message us about the interactive spreadsheet Economics of Vertical Farming in a Stationary Indoor Farm.

In the Vertical Farming Economics interactive spreadsheet, you can get the resulting return on investment for efficient local production based on the exact cost of electricity, the cost of water, the cost of operator labour and the cost of space for exact location. 

The information you give us about yourself and your intention will help us to prepare a personalised offer.
We will send you a link to the interactive economic spreadsheet by email within a maximum of two working days.
