Hey guys, I'm back from a really long hiatus. Man have I been busy! I now have a Flow Hood and have my sights on becoming a spore vendor soon. So be on the lookout for Egon's Desk Mycology coming to reddit and soon the World Wide Web. Hope to have a website up and running soon. 008e780e94c75b8c2ae70058240b650c.jpg

Just to answer a couple questions: The filter is a 24×24×6 99.997% at .03 microns from spycor.com. The motor is the Dayton 1tdt9 from electricmotorwarehouse.com . The main filter housing is 3/4" maple plywood and the motor housing is 1/2" birch.

No, I am not selling this, I built it to assure that I am working in a clean and comfortable environment. I will hopefully be a mycology vendor soon!

Proposing a cheap but extemely crutial addition:

Construct a perimeter extension min 1 foot long using any cleanable material that will offer linear steady flow.
Any MDF board with plastic surfacing does fine.

At the photo, under the working space there is a horizontal slit 4inch deep chunnel that supplies with the filtered air the backside ventilator.

Plus a nylon sheet covers half the front opening guaranting protection.

Nice hoods!

 

The benefit of adding the walls is pretty negligible because they are themselves a path of backwashed air to run back against the flow and must be kept clear of just like the edge.

 

If you ran a thick smoke test along any of the walls or work table of your hood you will see the smoke behaves wacky against the surfaces and there are some eddies that actually backflow against the stream of clean air.

 

That's why you don't work directly on the work table surface (use a wire rack riser) and avoid the walls of your hood by several inches at least.

Will consider the addition. Just waiting for a better work table that can take the additional weight.

There are literally a shit ton of these teks on this site. Or that other site I rarely go to because of too many d-bags.

You-tube is overflowing with teks now that legalization has begun. Plus all these people at home in quarantine, I suspect a lot more growing is going on.

Anyway, here's a great agar Tek video. This is the method and recipe I use and it works every time. I have only ever had 1 plate contaminated In hundreds of plates. I use the flow hood I built - (and the tek for my hood is on this 'topia).

Build yourself a flowhood including the filter (don't do that, buy your filter, it's cheaper) https://mycotopia.ne...steampunk's

Prints will still be made in a SAB but all agar and grain work will be done in front of the flow hood. I'll let you all know more as I progress.

Same here. This is where a still air box comes in especially handy IMO. Not saying that you can't print in front of a flow hood.

I do thank you for the experienced advise.

I have being avoiding to add a wire rack riser because I need a flat surface to work on.
Will it be OK if I use a sterile metal sheet on top of the wire rack riser?
How many inches should it be raised?

It should be raised at least two inches. The main point being to break up where the bottom of anything touches the table because this creates a vortex or eddie if you will that can connect all the way to the outside room air.

 

You could likely use a flat surface on top of the riser. I don't see why not. As long as the legs and sides arent solid where it connects to the table so that a vortex cant crawl down and around all wacky.

if you have a vape pen or other source of mist or smoke, you can actually see the flow patterns and where it gets all tangled - you want to stay in "the smooth"   :biggrin:

Honey, I need to buy this delta 8 thc vape pen so that when I eventually buy/build my LFH, I'll be able to test it.

Or if you would like a really thick smoke that doesn't dissipate as fast as vape  and can give you a really stunning view of the airflow patterns https://store.meterm...idges-p605.aspx
