megamix. feed the ground.



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.
Love the soil will buy more in the future for sure

from 311 reviewsVery impressed with Marshall Arachnids! Excellent, quick communication and were very helpful. Excited to be part of project safety net.

Absolutely delighted with the customer service, communication and the C. versicolor slings I received! Ordered first thing in the morning and they were on their way to me that afternoon. The slings are bigger than I expected and arrived well packaged. They are settling in nicely. Can't wait to make more purchases from Marshall Arachnids!!!

The bundle is worth so much and you pay an extremely reasonable price. The business is professional and has great communication. Fast shipping. Couldn't be happier. Absolutely will shop this business again

I purchased two Caribena versicolor slings from Marshall Arachnids and they arrived, among many other Ts, in excellent condition. Both slings have been growing rapidly, have extraordinarily vibrant colors, and huge appetites. I highly recommend Marshall Arachnids’ tarantulas to all!
