My first year of growing Caladiums, I’ve three on the go in a heated propagator (22c) in the gh and they are all just sticking their noses in the air, 1/4” - 1/2”.
My question is at what point should I either turn off the propagator or take them out and put them on a shelf in the gh?

(I appreciate its too cold to plant them out yet!).
Thanks, Kev.
