The one inch of water generally applies to more mature plants that are in the ground where the water is spread out over a large area. In containers, evaporation can force you to water more often FOR MATURE PLANTS, but also less often for less mature plants.

If your plants are still small, say less than 3 feet tall, you have to feel your way thru it. Check the soil moisture over at the side of the container away from the base of the plant. Dig down about 3 or 4 inches with your fingers. If the soil is still somewhat moist, hold the water one more day. If it's all "powder dry", go get the bucket. I have some plants that exceed 6 feet tall with lots of foliage. These require water about every 36 to 48 hours and I feed them every 10 days due to chemical washout that is the result of this frequent watering. Your soil should be "moist but well drained". Hope this helps.
