Looks like its gonna be some good substrate for my curly hair tarantula i even ordered some springtails to help keep the enclosure clean.
Love the packaging, love the tropical mix and will order more in the future 🥰
So just got the megamix. My first impression is that soil is a wonderful organic mix. You can see, smell and feel the difference in this substrate compared to any others ive used. I really love that a complete list of ingredients is given. I fully believe this will be a great mix for my bioactive enclosure in the long run.
The product is great! I love the substrate and will be ordering more.

We ordered a couple of tarantulas and they showed up in great condition and are doing well so far.
My sling ate right away and has been webbing up her new enclosure. Staff was very helpful in finding a time to ship and confirming information for pickup.
5 stars. Great pricing. Reliable seller. Packaged very well and most importantly. Healthy Spider. Received a few weeks ago and the spider is thriving!
I bought H. Pulchripes and 2 Sabah Blues and couldn’t be more happier. All the T’s showed up in great shape and bigger than expected. Marshall Arachnids is a top notch business.
Bought 2 Phormingochilus sp. Sabah Blues then had to go out of town. Marshall Arachnids worked with me on shipping the I decided to add another Tarantula and they did it no problem. Very good communication and friendly.
Healthy alive spider. Fast prompt shipping. Spider packaged well.

I received excellent service, great communication, and my Y. diversipes has spun an enclosure and molted all in the last 3 or 4 days. I'm very pleased and will be ordering from you again!
Great people to order from healthy spiders
My P. sp. ‘Sabah Blue’ came in great, it’s healthy and thriving and I can’t wait to see how it develops over the next couple of years. Thank you!
Ordered a female Ogre-Faced Spider. She came quickly and was packaged beautifully! Little girl quickly adjusted to her new enclosure and has already started webbing and eating. Watching her is so cool! Marshall Arachnids was very communicative the whole time.
10/10 would definitely order from here again.
My spider arrived safely and in great condition. He was well packaged and clearly healthy on arrival. He’s been doing really well since settling into his enclosure. Thank you for the great service and care you put into shipping him!
