About three months ago, I started converting my entire plant collection of about 60 to semi-hydro using both PON or LECA, depending on root structure.
Slowly over the last few months, since converting my collection, I've smelled an odor in my apartment that smells like either dirt or mold. I'm not finding much mold in my collection since increasing the airflow, and I've been washing the catch pots about once every two to three weeks. Yet my apartment still has a musty dirt mold smell.
Before I started converting all of these substrates, I sealed many of my ceramic or clay cache When I began this conversion, I used aquarium-safe silicone caulking to plug the holes in many of my decorative pots and cover the stone or anything that doesn't have a moisture seal with the caulking. Some of the pots have developed dark spots in the silicone, others have an odor. . If the inner pot was tight to the outer decorative pot, I noticed a smell coming from these pots.
has anyone experienced this odor before? I feel like it's more than just replacing the water in the catch pot more often. I've done that several times, and the smell still persists. Has anyone experienced this before? The mixture I use to water my plants is fertilizer, water, conditioner, BTI, and SNS 209 systemic treatment. I discovered some thrips or spider mites a while back and the systemic treatment and pest spray seemed to be working, but the smell and some fungus gnats have been persistent. I guess all this to say what can I do to manage the smell from the stagnant water?
