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.
Dark and heavy, but also fine. I hate getting tropical soil with huge charcoal chunks and whatnot. Also appreciate that this comes premixed, less mess.
The tropical substrate is perfect for the tarantula species I have that prefer more humidity than my other species.
The tropical substrate holds the burrows and moisture well, and I’ve yet to have any issues with molding, with the occasional mistings or corner waterings I do. I definitely recommend.
Let customers speak for us
from 356 reviewsThese folks are the nicest, most genuine and knowledgeable people in the hobby (at least that I know of). Anytime I have had questions, one of them is always quick to get back to me. Lastly, their animals are top notch. Every one i have bought from them is thriving and beautiful. Thanks again Marshall's!
They are so cool and interesting there web work is amazing

We just purchased our first Marshall Tarantula Crib the quality is striking. I love the purple color, but the construction is fantastic. Super strong magnets, beefy panels, and great air flow. I will be back. Wow!

Let me tell you I own several TC collabs…… this is better than TC’d own original creations, let alone the collabs! . Personally think TC should just hire this husband/wife team to assist in ALL their designs. I am ordering 5 more of the 4x4x7 models. Using for jumpers and smaller/juvenile T arboreals. I also own 2 of the large terrestrial enclosures. These enclosures are more secure, spacious and so sturdy. FINALLY an enclosure that’s worth the $ amount. I hope TC never discontinues these. I am stocking up, though, because I don’t want to be without. If you are on the fence, jump on over to the other side and buy it, in fact but many! You won’t be disappointed.

Super quick to ship and quick to answer any questions. Top 3 breeders oat

Tiny sling arrived safe and on time. She was well packaged and active/healthy upon arrival.

They are all doing great! Thank you so much, I love them 💗

This was my first order from Marshall Arachnids and I will say I was super impressed. My D.Diamantinensis was listed as .75" but I honestly believe it is closer to 1". It arrived well packaged, very healthy and quite active. I can just start to make out a bit of color. Rehousing went very well and they are now in their juvenile enclosure. I will definitely be purchasing other Ts in the near future. Highly recommend!

My husband picked this guy out for me.. one of the only tarantulas that scare me 😅 he's super healthy and already wants to zoop everywhere

Received our little guy a few days ago and he was super active out of the gate. Very confident and brave, can't wait to watch him grow!

This was one of the three tarantulas that I purchased from Marshall Arachnids as a first time purchase. It arrived on time and very well packaged. This T was much bigger than I had expected and quite active. It's eaten and is doing very well. I'll definitely be purchasing from Marshall again!

Packaging was great and slings were healthy. Awesome communication and very accomodating to my schedule.

This lady spider is a bad ass. Already adapting to her new home environment.

The slings are doing great good and healthy!

Ordering from Marshall Arachnids was super easy and they were very thorough with their communication. Everything arrived in perfect condition. I would definitely order from them more in the future!
