Cracking the Aquaponics Code: Outperforming Hydroponics by 39%

Aquaponics is a trending topic, but this finding on plant growth performance could be path-breaking for further aquaponics development. The Developonics team has published a new paper in the peer review journal Water (MDPI) with the title Lettuce (Lactuca sativa L. var. Sucrine) Growth Performance in Complemented Aquaponic Solution Outperforms Hydroponics. The results were beyond our imagination. Read more

lettuce grown on RAS and hydroponic water

Lettuce Growth Experiment

Today, Simon has started a lettuce growth experiment together with Tycho Vermeulen in Bleiswijk, the Netherlands. We are going to assess to what degree micro organisms in RAS water have an impact on lettuce growth by adding it to a hydroponic solution. The control group is a standard hydroponic nutrient solution for lettuce. We expect this experiment to take 8 weeks, and publishing the results somewhen mid of next year. Cheers!

Aquaponics Logbook

We are currently running an experiment on specific nutrient uptake of lettuce grown in hydroponic, and both one and two loop aquaponic nutrient solutions. To guarantee that all relevant data is available after the experiment, proper data logging is an often underestimated factor. The excel logging file can be used and adapted by everyone for personal usage. You can find the aquaponics logbook in our new section “Tools”. The tool can log pH, light, air temperature, air humidity, water temperature, volume, EC, N-NO3, N-NO2, TAN, P-PO4, K, S-SO4, Ca, Mg, Cl, Fe, Mn, Cu, Zn, B, Mo and converts ppm (mg/L) to mmol/L automatically.  It also allows you to log how much acid/bicarbonates you added to your system for pH adjustment purposes.
