Our 9 - 16l Pot Saucers are excellent value for money. They are far better made than most other pot saucers available. Using a saucer under your pot allows you to easily catch this run-off when watering, preventing it from spilling onto your grow-room floor. Our round pot saucers have tall sides and a wide lip to catch lots of run-off.
When you water it is always advisable to allow 10-20% of your water/nutrient solution you pour into the top of your pot to run out of the bottom. This washes out toxins and old nutrients which build up in the medium.
This run-off can then be tested for pH and EC/CF/PPM, giving you an insight into the plants requirements at different stages. Once the pot has finished draining, tip away the run-off to prevent the growing medium from re-soaking up the waste.
