LOL, I found that out the hard way when I went to water them when I got back from vacation.
But in 1 more week And see no gnats I will take out the sand and see what happens.
I have not seen a gnat since I got back, so $3.00 worth of sand did more than over a $100.00 crap.and yes close to that in shipping charges from those dam companys, we will not mention here.
Stay safe and high all.
