How much rain is enough to give my girls a drink?

So my 2nd grow show is quite a drive away, and I never know exactlty whats happening weather wise. I keep an eye on the local weather station website and was trying to workout exactly how many millimeters of rain is considered a good watering? Im expecting a wet december, jan and feb thanks to la nina. What do you bushies reckon is a decent enough rainfall in a week to save me a trip and fuel money

depends on the drainage of the surrounding soil, wouldn't take a lot though 10mm+, especially if she has some soil conditioners to retain water.

Cheers Joe, In beautiful creek soil with good drainage, I opted not to use water cystals or saturaid for this location. Expecting quite a bit of rain this season and root rot was an issue last time I used water saving products. Expecting 20-40mm between thurs/sun so looks like Ill let nature do her thing and leave the truck in the garage Never got my head around what amount of rain was considered enough to give your garden a good drink or only enough to wet the surface and not be beneficial.
