SP - It is my understanding that roots grown in water are considerably weaker than soil grown roots. (You may need to trim back those weaker roots when you "pot up".) At any rate you are in danger of root rot if you have standing water under your plants, so be very vigilant. What type soil are you using? Your jades look a bit etiolated - try moving them into more light. HTH -

I have had some jades in hydro over a year now & in some ways I prefer it. The concept of water-developed roots being weaker is a standard answer for transplanting from hydro to soil, but many hydro growers have success with it. In areas such as mine where the wind & sun constantly dry container plants in the summer it is an idea I will try.
Your plants could use more sun, but they look pretty good for zone 5.
You keep experimenting slyphish. Thanks for sharing your info.
