After the original drench (watering in), we should allow the pot to dry almost completely. Pick up the pot when you drench it. Feel the weight. After a day or 2 or 3…You will realize the pot is very light. It is time to water.
For the first day or 2; Stick your finger in the soil to monitor the dampness. In no time all of this will become 2nd nature, and you will soon figure out how many days between watering.
note: You water less in veg when the plant is small. In flower you will water at least a day sooner.
