Thanks so much for this info! Very helpful!Light - I grow them under LED lights in a tent. The tent has one transparent side facing a window so the plants get eastern sunlight until about 11:00. Lights kick on at 11:00 and kick off at 18:30.
Temps - 28°C high, 18°C low (average) all year, relative humidity average around 65%.
Media - Most are in granite chunks in clay pots. A couple are mounted on hickory bark, and the mounts sit in clay pots.
Water - (March-October) Every other day on average, when pots are mostly dry. (November-February) Slightly less often, checking that pots are completely dry. I rarely flush the pots, but my goal is to do it once a month.
Fertilizer - (March-October) I am currently using K-lite 12-1-1 at 0.5 g per gallon combined with fish fertilizer 5-1-1 at 0.5 tsp per gallon. The result is around 45 ppm Nitrogen per watering. I am also experimenting with adding 1 tsp per gallon Epsom salts monthly as a magnesium supplement because many of the leaves have large yellowish patches. (November-February) mixture is reduced to around 15 ppm. I also drench the plants in 3 tablespoons/gallon of Inocucor in distilled water once a month.
Thanks so much for this info! Very helpful!
