  • How does a flowhood work with mushroom growing?

    This model is a horizontal flowhood which creates a low velocity air flow that blows toward you. This air is super filtered and is 99.99% sterile. It can be used in any environment for many different things. The sterile moving air allows you to work in the space and open up substrate jars, bags, transfers, make spore syringes, work with agar plates and much more. If you ever experienced mold from inoculations, this will eliminate that.

    I was hesitant to spend the money on the larger flowhood, but glad I did! I also downloaded plans to build my own but after checking prices of quality lumber and blower the cost added up! I basically am paying $300 to have this whole unit built. I could spend hours trying to figure out the specs and size of the inner box to make sure the flow is correct. Mine as well leave that to the experts. Super happy with my purchase and great customer support! Zero contamination now with all my projects!

    Great build quality. Wood looks to be of better quality than I thought it would be with the soaring costs of lumber. Assembly was quick, my first tests are good, so I would say this is well worth the price!

    • I should have bought one 40 yrs ago.
    Nicely packed with Styrofoam all around. They took particular care in packing this item and you will receive it in two packages. Mine came a day apart. Perfect condition and I assembly it in 5 min like they said. I am very pleased with this purchase. I peaked in the inside of the main flow box and they did a very professional job sealing the cabinet insides. High quality fan and nice looking. This unit cost twice as much anywhere else (different brand) but you probably already know this if you did your prepurchase research. Anyway; Nice, nice nice. Thank you Midwest Grow, Nicely done.

    Everything is within Lab Specs

    • Great build quality

    Cons:
    I have been planning to build my own laminar hood for a few months now but with the cost of lumber sky rocketing and only crappy sub-par plywood available at my local Home Depot and Menards, I have been looking online for something like this. Although only a few reviews for this unit scattered around the net, I decided to pull the trigger. The unit arrived in two boxes, very well packed.
    I have an anemometer which can measure flow rates and find dead zones in filters. I was pleasantly surprised that this flowhood was all within spec. I was getting a constant 175-205 CFM with only the top left corner around 150CFM. The scientific lab ratings for laminar hoods is 100CFM, so this unit is properly matched with the correct motor. I am happy to see they included a lower MERV pre-filter, as the pleated one pictured looks too restrictive. Overall the build quality is great, you can clearly see this was not built in a home wood shop, as the cuts were done by a CNC machine. My initial AGAR tests have also come back without contam. The filter looks easy to change as well, just unscrew the faceplate and swap it out. Great job overall. Very happy with the value of the unit.

    Exceeded my Expectations!

    I work at a Bio-tech lab and have a degree in engineering. I borrowed some equipment from work to test the performance and capabilities of this unit. I found the laminar rate to be fairly uniform at 201 CFM. The range for this is 125-225 CFM. I noticed they include a lower MERV pre-filter now and I can see why. I bought a thicker higher 11 MERV filter and cut it to fit the housing. The flow rate dropped to 140, which is still in "Spec" for this unit but on the low end. I also noticed a few areas near the top corner that were 120CFM, but thats expected with such a pre-filter. I would recommend beginners use the included pre-filter, which will give you much more room for error when practicing sterile procedures working in the flowhood. When the airflow rate is reduced you must move slower and follow the labratory standards for working in flowhoods. Overall I think the build quality is amazing, I can see these were professionally built on a CNC machine and the packaging was great for a unit this size. Overall you wont find a better unit for this price unless you build it yourself.
