Still Air Box Mycology (Sturdy) Mushroom Grow Box Alt to Laminar Flow Hood Fume Hood for Mycology Supplies by USA Mycologists V2 (Large)

I made sure all the tubes were inserted all the way. I can zip up one end no problem. The other end I can not zip up. The cover is about 1 1/2” to 2” short. I can get it part way zipped up but the frame is bowing. I am afraid of damaging the SAB trying to get the end zipped up. I am left with either returning it or modifying the SAB so the cover will fit. Might I suggest a version 3 of this SAB so you can gain easy access to the inside without fighting with the cover to get it zipped up if you can even get it zipped up. Great concept poor execution. One star.

I normally don't write reviews but am taking the time for this one cause I think it's important for shoppers to know that the creators of this product really did fix all the issues you'll read about in the bad reviews. When I ordered this product I bought a different one as well from a different company thinking that if this product gave me all the struggles people wrote about then I can return it & use the back-up. I'm happy to say that the sellers note in the item description is indeed true - they took the negative feedback & fixed the issues. Important: Like the instructions say, if the plastic case doesn't easily slide over the frame allowing you to effortlessly zip it up, then you need to push the frame bars further into the joints. 1 thing I couldn't tell from the reviews/photos was how the arm holes were designed to keep in. I'm happy to report that the creators were really creative in their set up to both not let the air escape but also give the user easy in/out. They set up the blue material overlapping (there are 3 layers of materials, each pulled tightly with elastic). When you slide your hand in, it's like a maze your hand has to navigate to get into the box. The maze & tight elastic creates an almost solid seal around your arms, wrists, hands - whatever size is at the entryway it wraps itself tightly around it. When I say "almost," it would be maybe a Q-tip size opening on either side of my arm at the most. I needed this box to suck the humidity out of the air insode the box so I can work with dried flowers. So it was really important to me that humidity couldn't get in from the outside. I'm happy to report that the blue fabric the creator chose along with all the layering, is doing it's job excellently. I've been monitoring the humidity reading inside & outside of the box multiple times a day for a week now. I am very happy with this product.

I use this for plant tissue culture at home, it's a little nicer and easier to see through than a still air box made form a tote. Overall, I think it serves it's purpose well enough and is easy to setup. It has some small issues which are probably difficult to remedy with the design... it's light so it moves really easily unless you have it well weighted and you can feel air move in and out when you move your arms simply because it moves the plastic sheeting that covers the whole thing. I guess any SAB would have air go in and out as you move simply because of displacement; however, this one probably does it a little more. The 3-layered arm holes are a nice touch, I spray some alcohol in between them when I put my arms in and out, which I hope helps prevent any microbial contamination while I work. I'm pretty new to all of this, so I don't have a lot of experience to go on. I think I'll eventually move to a cheap flow hood from etsy or create my own., but this will do for now.

Pretty much junk. Having to shorten rods to get it to work properly. Won't sit flat bc the rods are too long making 2 of the corners come off the table 3 inches or so and rock around while trying to use.

I have used 2 other SABs from other manufacturers. This one is the best yet. It’s very roomy - 3x2x2. The plastic is pretty easy to see through, although it is subject to creasing if you take it down and set it up. ( I leave mine up.) You can use a hair dryer to minimize the wrinkles. This one has reversible zippers so you can open it from the front or back on each side. That’s handy when you need to use equipment that’s plugged into an external outlet. A bonus for me that most people wouldn’t care about is that the plastic blocks UV light. I use UV-C to sanitize the inside of the tent, and using UV detection cards, I noticed that the UV won’t pass through the sides of the tent like it will with my other tent. I still cover it and leave the room when it’s on, but good extra safeguard since there are other things in the room I’d rather not expose. I like the fact that the arm hole coverings are layered to impede air flow. One down side is that the bottom of the tent is just some kind of fabric which is not very sturdy. I recommend you buy some plastic sheets or work on an extra surface area because it’s really easy to cut with any sharp implements you are using. Don’t ask how I know…
