Re: heating and substrate soil moisture

The substrate soil I have for my Chilean Rose Tarantula seems to be still moist & it's showing against the inside glass in the tank. I'm really beginning to wonder if maybe it's due to the fact that I'm living downstairs in my basement bedroom & maybe the basement's just damp in general? The basement temp we usually keep around 60 or so degrees at night & 50-55 during the day although I'm using both a heating pad & a heating lamp (heating lamp I keep on everyday) for my tarantula. Do you suggest I should just keep mixing the soil around, or maybe taking some of it out, or just get another heating pad since the one I'm using is for a 5-gallon (wrong size)? I'm just concerned about mold buildup in my t's tank.

More heatpads will not help, you may end up rosting you rosehair. The easiest way would be to empty a part of the substrate and mix it with dry substrate.
Usually if it's that cold around the tank, you will always have a water build up on the sides of the tank, since the tank is much warmer. This is also the reason why your water will not evaporate properly (all physics) because the air due to the room temperature is saturated with humidity and will not take in larger amounts wich results in condensation on items - like your tank and also on the tarantula.
If you have a big tank where you can put in your other tanks it will help with the build up - to creat a bridge between the cold air and the warm air.
