I have for several years Lechuza pots in use. Therein are a pillar cherry and currant on the balcony. They thrive well and I need to water only once every 2-10 days (depending on the heat). But in the apartment I have the problem that always forms after a few days mold on the substrate surface, although I use pure Pon without soil, all the roots have washed beforehand, repeatedly airs daily and have filled the water level indicator only halfway. I have now poured the water and irrigate only from above at longer intervals. Unfortunately, I have so no real control over the proper amount. Since I did not bring anything the system. Too bad. But outside it's fine.
