Ditto. Pale pot, LFS only, chilled distilled water, indoors, a 1.
Bought in a 4" Lowe's cube in May, now crowded in a 7" pot, vigorously pitchering, and sending out runners to the edges of the pot. In spring I'll repot it into a larger pot and separate the runners. But I'll try to keep pot depth fairly consistent to help maintain the water table at a comfortable level. I may try one indoors and one outdoors next year just to see how they do comparatively.
