I can't tell you how to water, because your climate is so different from anything I have experienced. But to be successful, you will need to get over this:
"but i am not keen about checking if the soil is wet or the plant doesn't need water anymore until next time soon." The best fertilizer is the gardener's shadow. That means you need to be out there, paying attention, checking on how things are doing and what they need.
I also really recommend keeping some records. Next year you won't remember what you started when, indoors or out, at what temperature, etc. If you want to learn and get better, you need to know what you did before, what worked and what didn't.
I do have to caution you a little. Certainly people grow a lot of things in your country and you can too. Crops that come from Egypt include rice, wheat, corn, cotton, sugar cane, beans, citrus fruits, grapes, tomatoes, and potatoes. But some things like tomatoes, even though "sun lovers" don't really do well with very high temps, especially above 90-95 F (30-32 C). Look for heat resistant tomato varieties.
You are right, but i mostly not into plantation or gardening too much, i just started but i have other things i am busy with these days, and those tests in pots aren't the best i will have, but something to start with, and slowly i will do more and have more time for plants later, not in rush, and the site here could be a big help or assistant for me too, even after 1 year i can come here and read my posts so i can remember things, and within 1 year sure i will learn more and more.
I agree about very high temp, even we are human can't stand that very high temp, and that time of the year i will make sure to provide some kind of shades for my plants and watering more, i have some trees in my garden survived the high temp, even i remember that the end of summer still high temp last summer  i moved to my house and the person didn't water the garden and i didn't water it too for a bit, so about 1 month or more the trees or plants didn't have water under very high temp, but once i water them most plants/trees came back to life, but i will not forget them for next years in summer for sure so they can grow or live/survive better with me than before, it is life after all with the plants, in very cold winter or very high temp summer the trees or plants should die temporarily so they will wake up again in fall in our country or in spring in your region.
Again, we have nice weather only not in summer, and our summer is long, say from May until October it is bad time, then simply we grow out of that time, i started 2 months ago and i still have 3-4 months before the heat start, so i hope by May when it is warm the plants grown good enough or even some giving fruits by then, then with heat it may slow growing or die in peak summer, but i don't think all plant will die at once in very hot summer if i water them good enough, and this coming summer will be another test also to see which plant can survive and which can't, i will try to take care of my plant nowadays until summer so i can have stronger or healthier plants in summer, if some die or failed then simply i will grow them again after summer earlier this time to have more time before another summer [2017,.....]
