I apologize if this is a thread that already exists, but I couldn't find it.

I used to use bio dude and reptisoil but have moved on to making my own mixture as it gets expensive real quick with any even medium sized collection. Usually a mix of top soil, excavator clay, and coco fiber. Most recently I found a landscaping type place near me that sells top soil which already has clay and sand among other things in it. I worked really hard to find this place because they actually list the ingredients of the dirt and exactly what's in it whereas at home depot it will just say "forest products". I live in the pnw and found most topsoil has a lot of conifer/pine in it which I've heard is bad for tarantulas (but I had to buy it in bulk for my snake which is actually why I was so concerned).

What do you use? What do you put in your mix? Do you use conifer products? And is it easy for you to find topsoil without conifer where you are?

Appreciate any input, I'm always looking to try new things and have far from perfected my dirt mix.

You couldn’t find a single post on this? How did you search, and what terms did you use?

maybe this info could improve the site….

I live on the Canadian border somewhat close to Bellingham if you know where that is lol. Too scared about pesticides to be taking any random dirt from outside 😭

Haha of course I found some posts (mostly about coco fiber). I wish there was a thread with lots of people saying what they use and how they mix it up in one place, but I couldn't find such a thing. I was also unable to find anecdotal evidence of the safety of conifer products in substrate. If you know of one, feel free to link it ;)

maybe you didn’t search the right terms 🔍 it’s fine , I wouldn’t use anything with sap or ceder .
Cured pine I don’t know 🤷

I have always used coconut fiber and have had good success with it. Just be sure to pack it down to firm up the surface, as some Ts are sensitive to losing substrate.

Dosen't mold, dosen't collapse, is nice for burrowing, looks good and holds moisture very well!

Yeah I don't plan to use any lol I'm too nervous. I wonder if it causes respiratory issues like in snakes or if it causes serious neurological problems like dks symptoms 🤷

Do you have issues with fossorial species and coco fiber? I have always felt it doesn't hold burrows quite as well

I do not have fossorials. However, I would think that coco fiber would need an additive to make it bind better,

You are smart to stay away from conifers, any odiferous would secretes oils that are toxic to invertebrates (and actually used as insect repellent, e.g. cedar wood oil). Also very toxic to cats FWIW.

Personally I use reptisoil for just about everyone, because I don't "trust" anything that's not specifically marketed for animals. You still have to read the label as many reptile and mammal products include pine products.

I have the luxury of living/accessing the native distribution for many Aphonopelma species, and collect native "loamy soil" but still trek a mile from any show of civilization to avoid chemicals.
