How to measure PPM
Shagrathanswered grow question 5y 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

Nutrients alternativa friend wants to start with his first plant. Unfortunately, he doesn't have much budget. And through the Corona eruption, he has to work with what he has. As soon as he has the money, he absolutely wants to switch to the right additives. Is it possible to use one of these.

Fertilisershello! I'm using a prefertilised substrate with NPK 12-14-24 (Plagron lightmix).Which nutrients should I consider to buy next?
Plagron offers a NPK 3-1-3 or 4-2-4 for growing and a 2-2-4 or 3-2-5 for blooming. Beyond brands, what ratio should I look for, for what elements?
ThanksWeek 2

WaterIs it bad to make my water ahead of time ? I mixed my nutrients (big bud, formulex, bud candy & molasses) in with the water & have let it sit out for over a day. I heard letting it sit out gets the chlorine out (I put a towel over it though so my cat/other stuff would get in it)
