Welcome to the thirteenth part of my BiOrbAir Review – Growing Miniature Orchids in the BiOrbAir.  The BiOrbAir is a specialised, automated terrarium, designed by Barry Reynolds from BiOrb.  I first planted this Miniature Orchid Trial BiOrbAir Terrarium in August 2015, so at the time of writing – in May 2017, this BiOrbAir terrarium is 21 months old.  Some, though not all, of the miniature orchids that are currently growing inside this terrarium were featured in the original planting of this terrarium, which took place in August 2015.
