In comparing hydroponics yields versus field grown harvest weights, we look at the total harvest weights, per Acre, through a variety of common commercial agricultural crops in Soil and Soilless Culture.
The information has been adapted from Dr. Howard Resh’s Hydroponic Food Production, Table 1.2 3rd Edition.
Hydroponics 60-300 tons
Soil 5-10 tons
Hydroponics 28,000 lbs
Soil 7,000 lbs
Hydroponics 4,100 lbs
Soil 600 lbs
Hydroponics 5,000 lbs
Soil 1,000 lbs

While another article unto itself, having a brief look at greenhouse crop production in hydroponics yield potential versus outdoor grown crops is prudent in comparing hydroponics yields versus field grown harvest weights.
In greenhouse crop production inputs tend to be intensive and cropping management skills become more specialized and constant. Per square meter, greenhouse crops will yield considerably more versus outdoors, especially over the course of a one year time period.
Obviously where economic conditions permit, year round greenhouse crop production allows for several crops per year, or very lengthy and repetitious harvesting versus typically one or two harvests per year with most conventionally grown crops.
Borrowed from Agriculture Canada’s publication, Growing Seedless Greenhouse Cucumbers in Soil and Soilless Media (Publication 1902/E) here are some real working and practical planting calendars for greenhouse cucumber crops in Northern Latitudes.

Erik Biksa has been writing about and discussing hydroponics growing, related technologies and cropping methods since 1999 in a variety of professional publications and platforms globally Erik has travelled the world learning and teaching modern growing techniques and technologies and is appreciated by many growers for his informative yet hands on approaches. Presently, he is the Editor at Grozine Hydroponics Mag.
