PlantGuy's Chelated Iron (13%) (EDTA) 500g
We currently have 16 in stock.
Which type of iron you use depends on how hard your water is. If your PH is around 6.5 or below 13% EDTA is a fine option. If you PH is above that, DTPA 11% is a better option as the iron is available to plants for a longer period of time in the harder water
