KushGANGanswered grow question 3 years ago Hello for your watering you have to give between 10-20 % of the volume of your contener. So in your case (11L contener) you need to give around 1 liter for your plant. To know when water feel the weight of the contener. If it is heavy you don't need to water but if it is light you can water. Continue your good job. Bye
