Neal and others.
I can likely get these outdoors about Mother's Day or earlier. Here we do not get real hot and humid til June. In my basement I have control of Temperature (+ or - ~ 5-10 degrees), humidity (range of 40 - 70 %) and light (on/off hours). Granted the light is not real sunshine.
I have metal halide, & flour. with grow lights & natural light bulbs.
The half planted in the ground would not go in til early late April/May.
Those in a pot could be moved to garage if necessary.
