Converting S Repens?

[JoeQ]

Any advice for converting S Repens? Currently I'm floating  a few stems and planted (1) by my co2 diffuser.  I also might try submerging the stem on 1 with the top of the stalk out of water. Was any tactic more successful over the others?

I have bought s repens from a few different sources.

TBH my best results have been with tissue culture from local Petco.  I simply make sure the gell in the bottom is clear and firm and the plants look healthy, then wash out the gel, split them up and plant them.

These seem to do fine from the get go.  I have been disappointed with the other sources having them either die off in short order or just sit there and fail to thrive and act more like plastic plants than anything else for months on end…
