Great choice for a T, they're fast-growing, beautiful, and always hungry.
Thanks! Got their water dish and everything so we should be good to go! And it already ate after I just got it so I know it's got a super strong appetite !
it's loving it! 
I would remove the Ivy leaves and water dish and add some anchor points like small stick and it could be ok. Water dish is not necessary in this size, it is much better to add watter drops every two or three days. Also, they build and destroy their webs often, depending on molt cycle, before molt they build a lot of tunnels, several days after molt you will have only empty box with white carpet. Also, water dish and leaves will be covered by web and make only trouble, because you will have to clean it. Also, when you add a cricket in a premolt and they will not eat it, you need to be able to remove it simply.
I would keep the water dish since this species likes dry sub. If you try to provide water only by dripping it in the substrate, you would probably either end up with a dehydrated T, or soggy substrate. They won't down in the dish, and the enclosure has more than enough room for one. If they web up so much that you can't get the water dish out, there will probably be some webbing thick enough to just set another water dish on top of (that's what I ended up doing).
Thanks I have a B.Smithi and A.Versicolor. Mainly just a hobbyist getting back into the swing of things. Had a Cobalt blue about 8 years ago and was restarting and bow growing a collection
Btw I did add an extra leaf and twig for anchor points. Also really want to add an OBT or a P.Regalis eventually If you have bone dry substrate, drops stays there for several hours. Also, when you feed every day or every second day and regurally add drops on web or walls, no problem with dehydratation. And for slings are small drops on web/wall much more suitable than dish. It is valid for all slings.

Thanks! I have a couple Fri nds who are local with P.mets and I am super stoked for mine! I'm kinda hoping it's a male!
Maybe stupid question, but why?
My friends both have females
First of all, how long the water stays in the substrate varies depending on what type of region you live in. I'm not saying it's impossible to maintain a healthy sling that way, if you want to create more work for yourself, go for it. I, however, will add a water dish if the enclosure is large enough.
Super awesome bro. I prefer not to worry about needing to remove feeders. I agree that it's hard to recognize premolt sometimes, especially with a fast growing sling like a GBB. Which is precisely why I crush heads the majority of the time I feed, and it's not like the feeder is completely motionless after you give them a little squish, they still illicit a good feeding response. I don't like digging up hides and destroying webs if it's avoidable. But again, that's just my own preference against creating work for myself.
Also, no matter what enclosure you do, sling will rebuild it every second day. Also, it will be destroyed by you you will open it. Send photo and experience after two months
Always depends, man. Always depends
I think that problem is somewhere else and it has something to do with physics, surface tension and capillarity. As far as I know, small slings are not able to drink from dish as easy as from very small drops like dew. Also this is the reason why to try spray as much as possible (no amount, but small drops like fog or dew) and put water on webbing.Always depends, man. Always depends
There isn't a rule, there isn't a more 'better' or damn 'wrong' way to do things when and I say when the set up offered and the (needed, according to the specie in question) parameters are respected.
For instance, I've never offered something near similar as a water dish, to my slings, altough I love to suggest to beginners to use one, when possible. This because I don't nor I can't know how good is their 'care 101' basic level, so, since using one doesn't harm, voilà.
I always loved to pour directly, in the substrate, room temperature water. I'm not a fan at all of the so called 'misting'. Yeah, can work every now and there, on the fake leaves, for arboreals... but aside that, IMO useless.
You are right, misting is the best way for mildew
When I am writing about sprying, I mean only small place, 1-2 cm in diamater. When I am giving watter to my C. versicolor sling, I use syringe needle and add only several drops to wall and webbing. No misting at all.
