                                    Microposse poly film is a game-changer for working with AGAR. While Parafilm is the lab standard, it can be difficult for beginners to use and is three times more expensive. In contrast, Microposse poly film is cost-effective and won't cause plates to stick together like Parafilm. As avid supporters of mycology vendors, we use and love this product every day in our own lab.

                                            Why clean air matters: most failed grows start with contamination during transfers. A steady stream of filtered air over your work is the single biggest step up from working in open room air.

                                            Common questions

                                            What does a laminar flow hood do?

                                            It blows HEPA-filtered air in a smooth, even stream across your work surface, so airborne contaminants are pushed away from whatever you have open.

                                            Flow hood or still-air box?

                                            A still-air box limits air movement and works for occasional agar or grain transfers. A flow hood gives you a continuous stream of clean air and more room to work, which matters as you do more transfers.

                                            What is an FFU?

                                            A fan filter unit is a self-contained fan and HEPA filter. It can be set up as a flow hood on a bench or used to supply filtered air to a larger work area.

                                            How often should I replace the HEPA filter?

                                            It depends on use. Heavy 24/7 use in a dusty space can call for a new filter in 6–12 months, while light hobby use can go 36–48 months.

                                            Do you sell replacement filters?

                                            Yes. We carry replacement HEPA filters for regular, XL and commercial Bonsai hoods.
