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.

Not just a breeder, but a team that truly cares for their animals and has no problem answering even the simplest questions. The ordering experience was smooth and easy, and they were patient with my countless questions. I appreciate them greatly and Marshall Arachnids will be the go-to suggestion for any one I know looking to get into tarantulas.
Great packaging, and came to me alive.
Not only were they quick to answer all my questions and get a shipment scheduled! They were so friendly and informative. The package was right on time and my spood babies were safely packaged and came happy! Will absolutely order from them again! 🖤
Arrived on time, communication was great, and I received a healthy tarantula

Wonderful quality!! Spider arrived healthy and was packaged safely! 10/10
Purchasing and scheduling pickup were straightforward. No customer service concerns. Spiders arrived well packaged and with a temperature packet. Each also had a hatch date card and serial number. Both spiders were lively and readily rehoused. They've both made little nets when hungry. Will definitely purchase from Marshall's again!!
As i opened the vials they came in they were super active and nice size they looked well taken care of can't wait to get some other Ts
I am pleased with my experience dealing with Marshall Arachnids. Customer service is good and they respond to any questions and conserns quickly.
