Obviously each and everyone has to consider his/her own climate and seasonal temperatures and changes. If you are at the equator you have almost the very same climate and temperatures with only minor changes (28-32°C) all year round. In more "desert-like" or mountainous regions, you got these extreme changes in temperatures. In other more northernm but still tropical or sub tropical regions you got very hot and short summers, an extended monsoon season and a relatively short cool or moderate season.
Maybe
instructkamal simply tells us where the actual location is and what the yearly temperatures and the climate actually is, - before we get into a purely subjective debate on principles that do not apply at that end
I am in fact consulting with a colleague in Pakistan at the moment who has developed a heat resistant tomato hybrid
and yet faces serious BER problems from 30°C upwards. And here we are talking commercial growing according to high seasonal market prices, that at least legitimates the effort and the extravagance that is done here.
Especially for beginners and people who have more seasonal flexibility, I STRONGLY recommend to respect the seasonal climate if only they can. Simply avoid planting such heat sensitive plants like tomato and strawberries during the hottest months (like everyone else in the region does), because climatic conditions are clearly unfavorable.
Even if cooling down your
nutrients by any means there are or you may have at your disposal, the air temperatures may still prevent blooming or proper fruit setting with these. You can always go against all odds and "pull the plug" when it goes wrong again for the second or even third time, - but how smart is that at the end?!
