For saving space and soil, this method also has several
other benefits, including no soil-borne diseases, no
weeds to pull and no soil to till, run-of-the-mill side
benefits of soil-less gardening.

Different Plant Species

Plants growing in soil have widely differing preferences for pH. This is not the case in hydroponics and all plants in hydroponics systems will function best at a nutrient pH of 6.

Measuring pH
This is best done with a meter but there are also various kits available which use liquids and papers. Kits are adequate for applications such as pot culture where the nutrient is supplied to the plant once and is used up before being replenished. Growers using re-circulating systems such as NFT or Ebb and Flow will certainly need a meter to monitor their solution accurately. Meters will require regular calibration and instructions for this are supplied with them.
