Organise time in factory (5)
I believe the answer is:
plant
'factory' is the definition.
(I've seen this before)
'organise time' is the wordplay.
'organise' becomes 'plan' (I've seen this in another clue).
'time' becomes 't' (abbreviation).
'plan'+'t'='PLANT'
'in' acts as a link.
(Other definitions for plant that I've seen before include "eg Flower" , "Machinery; snooker shot" , "sold by garden centre" , "Place in the ground to grow" , "Factory; organism" .)
