What is Semi-Hydroponics (PON)?
Semi-hydroponics replaces soil with an inert growth medium. Why? Because soil hosts not only plants but unwanted pests along with them. Semi-hydroponics uses inert growing media such as LECA, pumice, or zeolite, which provide no organic food source for many soil-dwelling pests. Hence, it can help keep your indoor garden less prone to certain soil-related pest problems.
With semi-hydroponics, indoor gardening is finally under your control, as everything from watering to supplying nutrients is a calculated task rather than confused guesswork as in soil.

How to Switch from Soil to Semi-Hydroponics
Follow this simple step-by-step guide to switch your houseplants from soil to semi-hydroponics easily.
1. Prepare LECA or PON
Firstly, place PON or LECA balls in a strainer or colander and rinse thoroughly under running water to remove any processing dust.
If you opt for LECA, soak it in water for 24-48 hours to allow the porous clay pebbles to maximise absorption. You can skip this step for PON media.
2. Clean Your Houseplant
Choose the hardiest plant among your collection. Gently unpot it and rinse the roots under water to remove every trace of soil.
Tip: Trapped soil can lead to rot and pests! So make sure your potting media is completely dirt-free.
3. Ready to Pot
Fill the bottom third portion of your pot with LECA or PON media and set your plant in it. Now, add more potting media to stabilize the plant.
Tip: LECA is chemically inert, so adjust its pH with pH up or pH down solutions.

4. Time for the Feed
Add a balanced nutrient solution so that it stays within the bottom third of the pot. Let capillary action take its course, so don’t fully submerge your houseplants’ roots in the nutrient solution.
Tip: Flush out your semi-hydroponic setup at regular intervals because fertilizers can build up in the media.
Semi-hydroponic houseplants can be a great addition to your indoor plant collection if you want a lower-effort setup. So say goodbye to annoying pests and rot forever by going soil-less. Choose your best semi-hydroponic houseplant and start your soil-less journey. In no time, your houseplants will reward you by flaunting their happiest, healthiest growth yet!
