I am still building my flow hood and use a still air box to inoculate my bags. Works well enough for just a few bags at a time. I got one off amazon that works pretty well and folds down when not in use: https://www.amazon.com/dp/B0BQQ7GPCL?psc=1&ref=ppx_yo2ov_dt_b_product_details. Its nice because it has arm sleeves and is large enough to hold all the equipment needed.
