i have plants that grew at shitty heat and humidity, seedlings that don't grow usually have a bad case of shitty soil conditions. the seedling stage and the flowering stage are the ones you need to really study on to avoid these problems
i had one plant at around 30c on average and was watered...
the most debated issue since God knows how long. i don't.
i suggest trying both to see for yourself since it's kinda subjective. both sides have good valid points imo, no use fighting over it.
