I use 10 inch pots with lots and lots of drainage holes. When my moisture meter tells me the soil is bone dry, I add water, until at least a pint runs out the bottom. I use a layer of vermiculite close to the bottom, so I want it to absorb its fill of water. I don't water again until the moisture meter tells me it's bone dry again...:thumbsup:...this is usually 3-5 days.

Main advantage of a moisture meter probe, it can reach to the bottom of the pot; something, I can't do with my finger.
Dutch Pimp Reviewed by Dutch Pimp on . Watering question I know that the size and vigor of a plant probably have alot to do with how often a plant is watered, so i can imagine watering schedules vary from plant to plant... that being said. How much water should be used to water a plant in a 5 gal. pot, indoors, under a 400w HPS, that has plent of drainage?? I mean i know there is no one true answer.. but if anyone had any advice or experience in similar conditions i would love to hear about itt. Thanks all:) Rating: 5
