Huh? That's great to know. 
How do you tell if the plants need water, then?

Subject: [pbs] Fungus gnats

I don't know if it would be possible in a large commercial operation but years 

ago I read that pouring a layer of sand on top of the soil in a pot would 

eliminate fungus gnats, reportedly because the sand cut up gnats or their larva, 

I'm not sure which.  Can't beat that for organic,  My purely anecdotal and 

sporadic observation is that it works, though the sand needs to be periodically 

replenished if the pot is watered from the top.
