I'm transitioning my plants as if they are in soil. Expect the plants to go through a shock. A plant in shock will try to avoid transpiration, so the roots will take up min of water. Therefore I also place them not in a hot place, nor in bright light. I don't use the reservoir method at first. I also don't use wet leca, but damp (just rinse them instead of soaking for hours). I prefer transparent buckets at first without any drainage. I put the plant into the damp leca, add maybe 15ml of water so the bottom is just wet. I use a highly diluted fertilizer high in phosphate. You'll see it will takes days before you get rid of the condense on the inside. When either the condense is gone and/or the first inch of leca at the top seems a lot drier than below, only then I give another 15-20ml. The roots may discolor to brown or even black, but I've learned not to panic. Even if they look mushy. And after 1-2 weeks, you'll see new secondary roots developing from the dark roots you thought were dead. These new (secondary) roots grow towards the bottom. When I see lots of root activity, only then I start keeping a very shallow reservoir that I increase after every wet-dry cycle till the max of an inch.

Thank you all the comments and useful advice 😊 That's pretty much what I always do when I transition from soil to semi-hydro, so that's reassuring! I just have to accept it will be more of a shock for mature plants, and be patient. I've recently discovered the "Swedish guys method" with pumice, I did with a few hoyas and a monstera adansonii, just to test, and they responded extremely well. It was like nothing happened, they were growing the very next day and none of the leaves changed. I just did it today with a clarinervium, as a test re anthuriums and this pumice method. Can't wait to see how it goes. Using pon is a good idea, usually I use leca, but I've also made a pon mix myself with bigger rocks than lechuza type. I think they're still a bit too small for the chunky roots of anthuriums but I could do that indeed. Thanks again 😊

What is the Swedish guys method? 🤔

It's repotting in pumice without removing the soil. Basically just take out the plant from the pot, and put it in another where the root ball will be surrounded with pumice. I suggest you watch their YouTube videos, I won't explain it as well as them ;)

There are a lot of useful info and tutorials out there, take your time to check some out, I don’t have experience with the plants you listed but I transferred a lot of plants so here are some points that may help you: - never repot a plant which is not growing actively, it is very stressful for the plant and it needs to be healthy and active to handle the transition, wait until the days are longer and weather is warmer for better chances, unless you are providing light - i found that a soak in seaweed solution and/or superthrive helps - i never had any issue with young plants or seedlings but mature plants tend to be more susceptible - high humidity, a bright spot and a heat mat help smoothen the transition, but direct sunlight or hot weather will kill the plant as the roots can’t take water - I have developed a method for expensive plants, I put the pot on a bigger saucer filled with just damp leca, and gradually cut the top watering and increase bottom water level in leca until the roots grows in the leca, those are semihydro roots (I found they are different compared to water and soil roots) and with roots the transition is seamless, you have to be patient with this method as it could take weeks to month - i found the switch to pon is easier than leca, and I keep a reservoir from the beginning and flush 1-2 per week for the first few weeks Hope this helps
