Everyone has Their own method when it comes to watering. I use the three times rule. Pour or spray it, wait 20 minutes or so, then do it again. The third time I add fertilizer at 1/4 strength. It Depends on your time, amount of good water you have, etc. Our water is hard, so I use rain water for as long as it lasts. Never enough to get me through, so I have to be careful not to waste it. The best way to check those plastic pots is to stick a freshly sharpened pencil in the medium. You can tell whether it's moist or not by the wood of the pencil. Check the weight when it's wet, then check when it's dry, and you'll get to know how long it can go between waterings.
