Measurements Every Hydroponics Grower Should Take

Posted on May 8, 2014 by Travis Athougies

As I’ve learned from my hydroponics grows, making sure you keep good records is extremely important. Not only will this will you save money (since you’ll only replace the nutrients when you need to) but it also could save your plants. By knowing exactly how much nutrients your plants are consuming, what the pH of the water is, etc. you will be able to immediately respond to any changes in the environment that could spell the end of your grow.

I’ve put together a checklist of some common measurements that you could take every day. You should at least try to take the first four. Both pH strips/meters and TDS/EC meters are fairly cheap and are an extremely good investment. Thermometers and humidity sensors are easy to pick up at your local hardware store.


Here are some tips so that the data you collect is accurate.
