Semi-Hydro Okay, everybody. Tell me about Semi-Hydro. **What I'm currently doing:** \* I already bottom-water or self-water all my plants. I self-water whenever possible (based on the size of my clear planters pot and the cache pot. I even like taking non-pot containeers (like wine glasses, lol) and using them as self-watering pots. \* Some plants are hanging, and I want to make sure they don't get too heavy with a different substrate. \* I currently have: hoya (#1 in my collection), calathea (#2), philodendron, pothos, spider plant, bromedliad, cryptanthus, parlor palm, string of hearts, purple passion plant, peperomia, bird's nest fern, pilea peperomioides, cast iron plant. Also my two favorite herbs: thyme and basil. **My Questions:** \* what's the difference between pon, leca, and other substrates? pros/cons of each? Can just regular rocks be used, or is there something special about the types that commercial blends use? \* Are commercial semi-hydro substrates generally safe for cats? Two of my three are diggers and munchers. \* Are there any particular plants that do/don't like semi-hydro? \* How heavy is it compared to regular potting mix? \* I've heard semi-hydro eliminates fungus gnats, which I'm seriously overwhelmed with. Is this true? \* Are fungus gnats attracted to soilless substrates, like Molly's Aroid Mix? I'm wondering if I can at least keep my hoyas and a few others how I already have them. \* Any advice for moving from potting mix to semi-hydro? \* What are your hydro favorite fertilizers in the US? Thanks so much in advance for any expertise you're able to share! Photo of one of my wine glass hoyas for attention. \*FYI I'll be cross-posting this to a few other communities.
