Kohl rabi

Yeah, the first batch transplanted fine, no sign of bolting or whatever other detrimental effect is supposed to occur. I transplant most brassicas without issues. Cimi di rapa/raab is the only thing I've had go to seed in modules but that was likely due to them being left in there too long and getting dry.

Seed packets usually say not to transplant spinach either but mine doesn't seem to mind. Think as long as you minimise root disturbance by letting the roots fill the module cells/pots first, most things can be transplanted (except things with fragile taproots like carrots and parsnips...I have transplanted these in the past to fill in gaps but often ended up with funky looking roots).
