@@Athos, in these days i started to control the weight of the pot daily and I'm learning when water the plant. In my first grow i used a 8 litre pot so i had to give more water than in a 3.5 litre pot. Thank you all :pray:
<span class="link_user">@gingilu</span>, yes it is possible. Make an experiment and do not water until the plant starts wilting from lack of water; that will force the roots to hunt for water and you will have first hand experience how long it takes to consume all he water in the pot. You will be amazed how long it will take.
