The last test comparison has come to an end and it gave a chance to simulate a water system failure. The video below shows the effects of water loss for 24 hours both immediately and after a 48 hour period for NFT and media beds. You may be surprised at how fast the plants recover from the drought.

 

The humidity misters were still operational keeping the relative humidity at 60-70%, so results may vary depending on air humidity, temperature and sun intensity. If it is in a well stocked aquaponics system you will need to act fast to oxygenate the water tank the fish are in, and reduce feeding to stop ammonia spikes until you have fixed the water flow problem.

 

 

There will be a few more blogs on the electronics side of project, but while we wait for parts it gives us time to talk more about the general challenges in soil less culture.
