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 quite understand how this works, but
'you' could be 'thou' (historical second person pronoun) and 'thou' is found in the answer.
'no' could be 'o' (O resembles 0) 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" .)
