How to measure PPM
Shagrathanswered grow question 4 years ago
Well best amd probably only way is to have an ec meter. Ppm's are converted numbers from ec thats measured and differing from manufacturer the ec is multiplied by 500,600 or 700 to get the PPM's

The problem in plants when I supplying CO2Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?

ph ProblemsI have always used tap water in a big bucket that I scoop from to water. I am using Root Farm phDown. The tap water is 7.6 to 8.
If I ph the bucket the ph rises again within a day.
Is it Root Farm or should I ph only the amount I need per watering?
Do other ph down's do this?Week 10
