How to dissolve Hoagland solution in water?
For 100 ml of stock solution, here an example for Hoagland a) (see attachment Hoagland_Lsg_herstellen) we weigh the following amounts and dissolve successively in 20°C warm water. We carry out our experiments in Mitscherlich vessels, filled with 6 kg quartz sand. 0.5 ml of the Hoagland solution a) and b) are added to 500 ml of water per vessel.
