Place for plants: you no longer would have means to water them outside (8)
I believe the answer is:
hothouse
'place' is the definition.
(I have seen 'place of glass' mean 'hothouse' so perhaps 'place' could also mean 'hothouse')
'plants you no longer would have means to water them outside' is the wordplay.
I cannot really understand how this works, but
'you' could be 'thou' (historical second person pronoun) and 'thou' is found within the answer.
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is present in the answer.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for hothouse that I've seen before include "Environment encouraging rapid growth" , "pressurised environment" , "Environment promoting rapid development" , "Warm environment for plants" , "develop skills quickly here" .)
