hi
i've been put in charge of getting office plants for a room with poor sunlight and c. 150 square metres, in covent garden.

anyone want to make this a lot easier for me?

i get that we want plants that get rid of bad stuff from the air:

that dont need that much sunlight/heat
that aren't very hayfevery

preferably vaguely cheap, but i aint paying so who cares.

thank you drownedinousndn, you;'re my only ohope
