Mini garden

Run off will be about the only way. They do sell fancy sensors for this but they are like 300.00. I would just ph to like 5.8 and give them a good watering and you should be good. But if you want a tester look for Bluelab EC Pulse Meter - Coco soil media EC and moisture tester.

Hey, yes, you can mesure your PH in the runoff. It should be between 5.5 and 6.5. The optimal value should be under 6, because the PH will rise inside the coco in the most cases. Greetz

Check the runoff. In coco drop it around pH 6.2 below 1100ppm. Pour 2 x times the volume of the pots with a feeding solution stabilized with these ☝️ inputs.
