Welcome to the twentieth part of my BiOrbAir Review – Growing Miniature Orchids in the BiOrbAir!  The BiOrbAir is a specialised, automated terrarium, which was 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 August 2018, this BiOrbAir terrarium is three years old!
