Watering with ceramic cones (blumats)

This is only of interest for those using supersoil and adding plain ol’ water. Apparently its not a good idea to put nutrients through the pipes, as it grows algae and other potential pathogens.

Not having heard of blumats until I’d listened to a podcast where they were discussed and were highly rated by a commercial grower. The soil remains at a constant hydrated level allowing constant nutrient uptake, unlike the roller coaster of saturated and dry of hand watering. (I speak for myself)

For a mere US$ 8.00 I ordered 10 RODE Watering Stakes from Aliexpress (link). The packaging was minimal however none of the ceramic cones were damaged or broken.

In the advertising, it showed a glass below the ceramic cone and implied that it would suck up the water. In my experience, it’s worked better when the water is above the cone and a syphon effect keeps the water flowing. It’s important to make sure that the pipe and cone is filled with water to ensure a syphon is effective. It’s easy just immerse the whole lot in a bucket of water.

To add compost teas, is straight forward, just add the tea to the plants by hand from a watering can.
The photo below shows a ceramic cone in the soil and another new one with the tube wrapped around the body of the cone. I use quart mason jars and the plants that are now 5 weeks old use about an inch of water from the mason jar a day.

That’s a good link about how to use the blumats troph with the reservoir. The blumat classics are the style you bought knockoffs of. Most people find blumat classic to be too low a volume to keep up to a big plant.
I tried blumat classics for my bonsai mother’s but they just seemed to be unpredictable and sometimes stop working. Great for a couple days away though.
