Substrate and enclosure size advice?

[Tina Banana]

My A.Geniculata's just molted recently and i decided it was time for her to get a new and bigger home (cause she's been living in the same box that she was in when i got her at the pet store). She now has a 3-inch legspan and i got her a 11-inch in length critter keeper. Is that too big for her? Because i read that giving a tarantula too much space can make it feel insecure and causes stress.

I also went to the pet store to get some new potting soil but it was out of stock. However the owner suggested me using spagmoss as a replacement, he said it was for keeping frogs but worked fine for tarantulas. Can you guys give me some opinion on this? Is it a fine substitute for my T? Here's some picture of the packaging:

Thanks!

I wouldn't keep it on straight sphagnum moss but u can mix it with other substrates like soil, peat moss, or eco earth. And the size of your enclosure should be fine also.

I like to use moss as a surround around the water dish. It absorbs excess water when you fill and holds humidity well. Your species loves humidity so you should have some moss. I find cocoa coir is the best tropical T substrate on the market. I mix in a 25% vermiculite amendment to assist with draining. Good luck!

I must agree with "trailblazin02".

something like this Rubber Made 1 Gallon Square Container is simple gives the height I use a drill bit for making door knob holes and cut a hole in the lid then add a plastic screen to cover it. Toss in a cork bark log for it to crawl into and some plants and you are golden. Any of the substrate ideas above are good. these containers are cheap like 5-6 dollars. stack well with other of same type and have a easy to grip handle built into it. The sticker on these peal off easily no solvents needed to remove it just peels off. Oh I also add breathing holes to the bottom 4 at very bottom at each corner and 4 just above those this allows me to occasionally drench the substrate and allow the excess to drain out. These spiders in the wild have periods of time where there is heavy rain fall. The flooding and allowing it to dry back out simulates this. Without bottom holes it would mold up quickly. K-Mart carries these still. I am sure your area has something similar.
