Vacation for 8 days

[Capensis]

Welp, I'm going tomorrow for 8 days. I going to leave about a little more than an inch of water in my 10-gallon tank (I think it might be a little bigger, it has like two extra inches into it) for humidity. My tank as two reptile lamps compact fluorescent bulbs (compact are the spirally small bulb, right?) and the lamps cover most of the top and I have tin foil around the whole tank ('cept the top of course). I think one bulb is like 75 watt or something like that, I think I threw away the case thing for some reason and another one that isn't as bright (I think, the lamp is smaller than the other). So, is it sounding good or bad and about hopw long might it evaporate (yes, I have my sundew and my vft seeds and cutting in their own pots with water)?
