Thanks and yes I know. This will be a bit traumatic for them surelly but handwatering every 12 hours is becoming back breaking and since my back is already broken and I am in wheelchair I kinda want a less work intense setup.

I will start with one, my least favoured plant (thay are all beautiful and almost perfect tbh but I can still rate them) and see how it goes. If it goes smooth I'll go on with the others and if not I transplant into bigger pots with coco.
I am also a bit interested in doing this for research reasons. Will be interesting to see just how roots spread in the medium and how stress sensitive these plants are.
I have clones from all of them and one of those clones or two will become the mother of all my future WWs so a bit of a stress test will maybe sort the bad ones out.

I will keep you informed.

Any other tips concerning practically how to do this transplant in the best way?

Cheers
