Full flow hood build write up (including links to items used) is here: https://www.patreon.com/posts/78502280

If anyone is looking for the Mycocoil (foot operated induction sterilizer) shown in the video it is here.  And here's an example of the silicone tipped tongs that you can pressure cook and use for mixing grain spawn with substrate which is better than using your hands.  If you want petri dishes that can be cleaned and reused, the glass ones are an option but often break in shipping, polypropylene ones are probably the better choice and they are less expensive.

Can I use my 6 in infinity fan instead of buying the 8 in ?

Thanks! I got a philips filter. Is the direction which side I place facing outside important or is the air flow equal no matter how I turn the filter?

I built this and it came out great. Thanks. The working space is a bit small, so I bought a 200 quart container with lid to increase work area. Problem: can't find a HEPA grade filter in 14 x 30 size, but I found this one: https://www.amazon.com/dp/B00TUDHSL2?psc=1&ref=ppx_yo2ov_dt_b_product_details Questions: 1)Do you think it's good enough? 2)Do you think the 8 inch raxial fan is strong enough? Could I use 2--one on each side?

No, sadly, the MERV-13 filters will not work for this project. You can read more about MERV ratings here: https://www.epa.gov/indoor-air-quality-iaq/what-merv-rating But bottom line is that you need a true HEPA filter. You CAN indeed use two of the recommended filters side by side, a bunch of people have already done that and reported success (there is even a picture of one in the written version of the TEK: https://www.patreon.com/posts/78502280 )

I did see that, but you don't really have a bigger work area; you have two of the same size work areas because of the split in the middle. Anyway, thanks for the reply. I'll just work with it.

Thank you! I built mine today, I did it for $114 all from Amazon. So that’s probably why I went over $100. But I’ll take it can’t wait to put it to use. I expect this to be a game changer, especially when it come to agar work.
