I grow Hoya blashernaezii ssp siariae in a four inch net pot which allows me to check root health and see more easily when the plants needs to be watered.  I seems very happy growing under T-5 fluorescent light in a grow tent that stays in the low 80°s F during the day and drops to the upper 50°s F at night.  It grows in my regular chunky mix without any special demands.  I fertilize with every watering. Tomorrow we wrap up the discussion of this this plant.
