Liquid PH testing kit

legalcanada said:

Can you use a liquid PH tester once your nutrient solution has already been mixed and it is no longer clear? Just wondering how that would affect it .... I already mixed my solution (incl. molasses) then dropped my PH meter and broke it, don't want to pay hydro store prices for another one and need to feed today. Will I be able to use a liquid testing kit?

I haven't owned a pH meter in years. The drops are never wrong, whereas a pH meter can go out of whack without the user realizing it. The drops aren't expensive, they don't require 4.0 and 7.0 calibration solution , storage solution, and cleaning solution. I found that the colors on the bottle were a bit off so I use this for color comparison - also has .5 colors for better accuracy.

Apart from growing a bit one of my pastimes is keeping a couple of tropical fish tanks. Part of the fishkeeping hobby is to occasionally PH test the aquarium water. PH strips are generally considered quite unreliable in the fishkeeping world, and an API PH testing kit is what most of us use. This consists of some test tubes and various bottles of solutions depending on what you are testing for. This works great for testing -the water you are watering the plants with and also the run off from your pots. I don't know what hydro shops charge for liquid PH testing kits, but the aquarium version (API)can b e bought for around £25(UK) which works out around $30 (US) once you have a kit it lasts for years.
