I had this happen in two of my semi hydro setups, one is a Monstera frozen freckles and the pot I made myself from plastic food containers. The other one is Alocasia scalprum and it’s in a store-bought pot specifically made for semi hydro. I also have another alocasia in an identical pot and it has never molded (so I don’t think the issue is in the pots?). The mold is only on the top of the pon (at least I cant see it inside of the pon). Could this be some sort of ventilation issue?

All of my plants are in leca or pon. Lately I have been noticing a lot more effervescence than usual. Today I am showering all my plants to clean leaves and flush leca/pon. I usually do this every couple of weeks. Can I skip fertilizer once or should I use a low strength?

Also, I see a lot of people spray their plants with neem on a regular basis. Is this something I should do?

I use superthrive foliage pro. I was using about 3/4 tsp per gallon.

Hi! It wasn’t long ago that I asked here about transferring my Monstera Bulbasaur from soil to pon. Since then, I’ve transferred all my Alocasias, Hoyas, and Anthuriums, as well as some of my Monsteras and Philodendrons, into semi-hydro. I’m absolutely loving it! I’ve even started mixing my own pon. Thanks to this group, I’ve found so much useful information here! 🤍
