Murray shows around his greenhouse, the tomatoes and lettuce growth is amazing. a short discussion on ec. what is it? http://www.aquaponics.net.au. “ec” stands for electrical conductivity. salts conduct electricity. the meter measures the level of salts in your nutrient solution. certain plan types grow best with certain levels of ec. lettuce and greens – low ec. tomatoes and peppers – start out with low ec, then move to high ec as they fruit.. I have just started with hydroponic growing. i am just tomatoes to start. my ph is correct at 6 but after i have added the nutrients as per the instructions, my ppm only reads 575ppm and my ec is 1208us/cm.. do i need any adjustments in the nutrients. i use the 3 bottle system, grow, micro and bloom. hope you can help in this regard. cheers cedric.
If you feed lettuce with a high ec intended for tomatoes, the lettuce can become bitter. likewise, if you feed tomatoes with a low ec, suitable for lettuce, the tomatoes will be tasteless! convert tds and ec readings tds = ec reading (in millisiemens/cm) times 1000 and divide by 2. ec = ppm times 2 divide by 1000.
