What's Going On Inside Your Pot?

I often sit down with customers and go through what they need to do to get their plants growing again when they are experiencing problems.

One thing that I find myself having to do is to get the grower to go back to their plants and find out what's actually going on inside the pot. I'm often faced with the reaction, "What, you mean there is a way I can tell what's going on inside my pot?" Well, the answer is "YES".

Simply put, guessing at what the plant wants / needs won't get you the HUGE RECORD BREAKING YIELDS we all work for. Experienced growers learn to read the plant e.g. the colour of the leaves or stems, or if the leaves are tipped up healthily towards the light. These are little things we learn over the seasons - the tell tale signs as to whether everything is working as it should be.

So, lets say you look at your plants and something isn't quite right then you need to find out why. So here's how to find out what's going on inside your pot:

  1. Take 10 litres of plain water - pH 5.5 - 6.0 - make sure you make note of the pH level of the water that you are going to pour through the pot.
  2. Take your plant in its pot and place it over either a washing up bowl or bucket. Start to pour you pH'd water into your pot until the water begins to pour out of the drainage holes in the bottom of the pot. Once you have collected about a litre of water you can stop - this should be enough to conduct our test.
  3. Take the litre of run off water, take your pH and EC meters and test the litre to find out its values.

The following rules apply to the pH results you will get:

Now for your EC values:
