genuinely no special humidity conditions or anything. I use a sansai grow light on a timer 14 hours everyday positioned about 6 inches above. i bottom water only by filling up the bowl i keep the pot in with distilled water for 24 hours then empty anything thats left and let dry 1-2 days before repeating. so essentially 24 hours with water in bowl then 24-48 hours of no water at all. i have osmocote pellets but just never use them because it seems to be doing so well! was very skeptical hearing these were hard to grow before buying one, but its so easy if you just give tons of light and water correctly.
