What kind of container are you using? Do you have adequate drainage? Are your containers in some kind of basin that would catch and hold run off?
I water using a partial submersion technique:
First I put my plants in a basin and then I fill the basin until the bottoms of my pots are about 1/2 inch underwater. (i.e. All the drainage holes in pots are submerged.)
Second, I water each plant from the top slowly until the entire pot is fully saturated with water.... that is, water fills the pot above the soil line almost all the way to the lip of the pot.
Once the pot looks like a lake with a bush in the middle I watch for bubbles. As long as I see bubbles, I continue to top off the water in the pot. When the bubbles stop, I stop watering that plant and move to the next, repeating the whole process.
At the end, I remove the plants and put them in an identical basin, but this one is dry. (empty. no water.) I let them sit there for a few minutes (smoke a bowl...) and then I set them all on a towel for another couple of minutes... and then I put them all back in the cab.
I do this every 3-4 days. When my plants were young, I could do this once every 7-9 days and be just fine.
