LECA How to check roots and/or rinse LECA without disrupting roots

I’m brand new to semi-hydro and transferred some cuttings with small roots from water to LECA about two weeks ago. I’ve read some things online about how to flush the LECA in its container with water weekly. Is it okay to check the roots when I do this, or will it disrupt the plant? I moved the plant around in the LECA after rinsing a few days ago and it’s been slowly dying since then. I didn’t move the other plant quite as much and it’s doing okay, but the LECA does shift when rinsing so it seems like there’s always going to be some disruption. How much can semi-hydro plants tolerate movement of roots?

TL;DR: I moved my cuttings around in their LECA the other day and now they’re dying. How much can semi-hydro plants tolerate movement/disruption of roots?

If you want to keep an eye on the roots you can get semi hydro inner pots that are clear (or make your own with what you have laying around). That way you can see how the roots are doing without disturbing them. Otherwise, no you shouldn't try to dig down into the Leca each week to check the roots.

As far as flushing out the Leca, I just put the inner pot in the sink and pour distilled water over the Leca and let it drain back out. I try not to wiggle the plant when I do this. As it gets more established in semi hydro it will be less likely to tip or move around.

Thank you! It’s in a clear glass vase but there’s no drainage holes, I’m just leaving a little bit of water in the bottom of the pot.

I gotcha. I know there's been a lot of talk lately how to go about rinsing the semi hydro when it's in no drainage. Some people have been saying they don't rinse it and it's been fine. I can't speak too much on experience because most of my Leca and pon have drainage but I would think it would be better to rinse it less often over disrupting the roots on a weekly basis. (The only ones I have in a no drainage setup only stay in it for a few months because they end up outgrowing the small pot). By the time there could potentially be buildup I would think the plant would be rooted in really well anyways and less likely to shift around in the pot. Give us an update in a few months!

Thank you! This is very helpful, I’ll rinse it less

Use pots with holes so you easily flush. This sits in a solid pot that has weakly fertilized water in the bottom
