Vertical Garden in Kolkata

An outdoor green wall along a busy corridor like EM Bypass or Salt Lake's commercial stretches is catching dust through its foliage all day, which is why we choose broad-leaved species over anything fine or hairy-leaved that clogs and stops filtering effectively.

Indoor walls in lobbies and meeting rooms face far less dust, so the choice there is driven more by light levels and the look the space needs than by air quality.

Building a wall that sheds Kolkata's rain

An outdoor panel has to shed heavy rain through the monsoon months without waterlogging the growing medium behind it, so drainage behind the panel is engineered before the irrigation line feeding it is even run.

We inspect every wall monthly through the wet season for panels holding water and swap any plant that is struggling before a patch of brown shows from the street or the boardroom.

Live or artificial, decided by exposure

A facade in full sun and road dust for most of the day is often better served by an artificial wall, since it needs no irrigation line, no drainage correction and no monthly plant swap while still giving the same visual result.

Indoors, a lobby or meeting room usually gets more out of a live wall, since filtered light and steadier indoor conditions let the planting establish and the wall keeps improving rather than staying static.

What a wall costs the building in upkeep, not money

An outdoor living wall needs its irrigation line checked before every wet season and its drainage cleared of leaf litter that collects behind the panels, since a blocked outlet is the single most common cause of a wall failing here.

An indoor wall needs far less of that structural attention, but the same monthly leaf-wipe and pest check that a potted office plant gets, since the panel format does not change what humidity and dust do to the foliage.
