Thank you.

For my tanks I'm just using normal bulbs 100w but I got a very cold house. All my vines n plants I buy at the dollar store, it saves you a lot of money, instead of 6 buck for 1 little plant you can get 6 big different plants / flowers / vines of your choice for the same 6 bucks pretty much the same quality too. Reptile bark is better in the fact that you can feed on it without the worry of it being ingested and killing your snake, where as coco husk can be ingested easily if not very careful and can and will kill your snake. But it really just depends on personal preference and availability. Coco husk like I got I find hard to spot clean cause its just so hard to see (Mind you she favors pooping on the fake rock so it seems lol) reptile bark I hear is very easy to spot clean.

As far as temps go, I don't have heat mats just lamps. Now I shut the lights off at night of course and allow my tanks to get down to house temps which go down to 17c or about 60f. I have been doing this with my Radix since I've had her. In Alberta Canada that is about what the temperature drops to on a summer night so I figure its ok. During the day their tanks get to about 65f - 70f (cool side - Warm side) Now this is just me, most other keepers probably do it a wee different.
