TLO grown running perfect pH!
If checking a container with a plant in it, make sure you know vaguely where your spikes are at,
because they will run different pH ranges than the rest of your soil mix. Always make several checks
in a row, reading each one, and this will really help you see the true reading zone of your mix. I keep
my meter in its package so it is not just hanging out in the air, as it does react very slowly with regular
air over time. I recommend keeping it in some kind of sealed container or freezer bag for these very
reasons. Also, never use any kind of cleaning fluid, or alcohol on the probe; only water if necessary.
To tell you the truth, if things are set up right in TLO growing, you rarely need to concern yourself
with pH meters of any kind. However, while you are learning to grow TLO style, or even just
organically in a soil mix, I highly recommend you get yourself a halfway decent soil pH testing meter.
It will really help you to narrow down many problems immediately, rather than months of trial and
error testing for what is wrong.
For Liquid pH Testers Hanna Brand Rules
As long as you are not mixing up mad organic liquid fertilizer blends all the time, you probably will
only rarely have any need for a liquid pH testing meter. Again, as above with the soil meter, these are
nice to have if you can afford one. Hanna brand meters are the only brand I will ever get (for testing
the pH of liquids) if at all possible. They are bulletproof, and they stay calibrated for the greater part
over long time spans. Don’t worry about a liquid pH meter if you are going to grow the TLO way, you
