Orchid Updates: ph, self-watering pots, fertilizer
The self-watering pot is a success! The Mps is doing very well, there is visible root growth and the new growths are doing well too. That's a relief. This weekend I hope to put my Oip and M. tenuifolias into the same kind of pot.
I decided this year to stop using time-release fertilizer. So now I am working on dialing in the Ph and TDS of my fertilizer. ph is an unexpected struggle: RO water has a Ph of about 5.5, and once I add fertilizers and etc, the ph is usually 3-ish. WHich is way too low. Even adding silicon, which raises Ph, isn't getting the Ph high enough. The other day I used baking soda.
I am torn between ph-adjusting my tap water down, and ph-adjusting my RO water up. I posted in OA to get opinions.
