Question
Hey Chris it is me again. I am having a hard time reducing the PPM in the soil. I took fresh long fiber sphagnum right out of the bag and placed it in a pot. Then I poured the filtered water through it. The water entering the moss had 0 PPM but after it went through the pot and gathered in the watering tray it had 15 PPM. How in the heck am I going to get beautiful Drosera plants if the very soil media contaminates the water?

Thanks again,
Tom

Answer
Hello Tom,

15 parts per million is not going to harm carnivorous plants. What occurred is the small amount of mineral solids in the soil were carried out of the soil with the water. It will now collect in the tray over time with some reabsorbtion of the solids as capillary action occurs in the moss. Since you have very little solids in the final product, I would not worry about it. The solids should be less than 50 ppm. Above that will harm Drosera and Dionaea.
