@Equatorial Please listen . 43 c outside pot is 38 c inside pot [ soil temp ] , day after day will cook you roots . Cook you roots and you limit the return for your time spent , Your soil temp will cool at night but not much , you daily average will be a judge of the soil temp . I would say you soil will not get lower than 28 c . -- 26 c with a breeze , But what you have is a micro climate , [ Balcony ] with is an other story . Breeze will be another issue you will have to deal with later on . What is you average Humidity in March to April and average temp for both months .
