Indoor grow I have. In pure life soil. TSW lights 75% strength Mars hydro LED. They are 3 weeks old. They will be going outside in couple of weeks to harden off. But my question is what PPM range at this stage 3 weeks and so forth?? Please advise

In pure life soil.

The Pure Life Soil from the company that is located in Toronto?

I did not know that if the plants are being grown in any decent organic soil mix would need to have the PPM checked. The PPM numbers were more important in a hydro style of growing where the plant has to rely on what is in the nutrient and water solution

It would seem to be the same sort of thing like checking the pH in any decent organic soil where the numbers would be changing every 15 minutes or so depending on how active the micro-organisms have been living reproducing and dying which would influence and change the numbers.
