Скачать или смотреть Major Con of Growing Orchids in Semi Hydro in Self Watering Pots - Fungal Disease

For a while now I have been suspecting my Oncidium Dancing Lady Orchid has a Fungal Disease, and this can be considered a major con of growing orchids in semi hydro in self watering pots. But this is not really completly true. Yes, my orchid has a fungal disease, but this is because of my mistakes.
So, learn from them, please:
1. I didn't cut off the roots which were less likely to adapt to semi hydro. I suggest you cut off any roots which are older than 2 years, assuming the orchid grew one psb per year.
2. I didn't come back to cutt off the roots that didn't make it after 1-3 months. In this period, any roots that could adapt, already did. The rest, are dead, decomposing inside your media.
3. I didn't properly clean off the reservoir and left dead algae to accumulate too much.
