This simple but very effective mushroom growing kit is the original product that Mushbox started with in 1999. Sticking to our roots we try to keep this mushroom kit as basic as possible.
This kit comes complete with:
  • 1 Rye grain jar or other substrate
  • 1 grow box
  • 1 dome lid
  • 1 bag of casing soil
  • 1 bag of shredded straw
  • 1 package of casing starter
  • 1 spray bottle
  • 1 mixing bag
If something works there is no reason to change it right?
The Mushbox casing kit makes it happen for beginners, and it's also a proven method for advanced cultivators to get up and running quickly for producing large quantities of mushrooms. Using a rye grain jar as the base starting substrate, (you can also choose other options) moving up to straw and casing soil you can build up the layers creating a robust block of healthy mycelium.  From there all you need to do is provide the 12 hours of light and keep the temp. / humidity at the right levels and you will have plenty of mushrooms pinning before your eyes.
It's this casing technique that creates massive mushrooms over and over again producing multiple harvests with giant fruits.  You can grow almost any type of mushroom that will use straw as a nutrient source, such as oyster mushrooms.
Note: This kit does not come with any spores or cultures to get started.
Quick Shipping, Quality Products
Although the casing method is one of the harder methods to start out with, this Mushbox casing kit makes every step as easy as possible. Make sure to familiarize yourself with the instructions before starting and you shouldn't have any trouble!

very VERY fast delivery
I ordered this grow kit and was very surprised at the speed of the delivery. The customer service is amazing as well. Very professional I was actually skeptical that I would even receive my product after reading countless reports of other peoples experiences with websites other then this one, but needless to say I got the kit in three days. I also ordered from their linked site spores101 and got the random grab bag and received the spore syringes the same day as the grow kit I love my new hobby

There’s no customer support. I bought this thinking it was “everything you need” to grow. I suffered. Lost $100 and everything wasn’t even packed. The bottom was missing from the grow tray. Worst. Don’t waste your money.

Mushbox casing kit
I got my item no problem. I was missing something so I contacted customer service and they sent the missing item out asap. Great customer service. Now as far as the inoculation goes that's all on me and I am having trouble. Overall this company will respond to you if you reach out to them and will make things RIGHT! I hope I get growth and no contamination on this second rye jar. Although this review on the item really wont help anyone due to the fact that I have not gotten past the first step maybe this is a little early for reviewing. Just got a e mail requesting review and thought I would comment on customer service.

Great in everyway!
This has to be the most trusted site i have used for anything you need, and this product is fantastic for: quick, easy, and great yields. Coupled with spores101, this box, and the newer incubation-tubs that it fits inside of are all you need for growing fantastic fungi fast! Thank you for a making a product anyone can figure out, can get extra CLEAN substrate jars, and those who do it once can keep it going with easy orders from your site.

Good kit for bulk mushroom growing
This is the first mushroom kit I ever tried and it was an excellent learning experience. Duplicating this casing method on a larger scale we use this method for growing edible mushrooms in bulk.
