DIY Laminar Flow Hood

[Deebs]

So the plans I was using were from @SCJedi , but I also used the fresh cap mushroom video as a guide. I will share some of @SCJedi (hope you don't mind me sharing pics) build where he put the fan inside the plenum. Though there is a Prefilter box shown in the plans

I wouldn't. Just build a flow hood or use SAB
To me the box fan with a decent filter is better/ cheaper choice, but not practical.

If you plan on anything morethan a couple of 6qt bins now and then you need a flow hood.

I'm just getting into this and am no expert. Just my thoughts

I'm getting materials together for my flow hood build. Now

Ya, I ear what your saying.
Seriously, I can’t even justify one of these really, but I think your right.
The way Deebs is going is definitely a nice build.

Bad ass Deebs.

Any plans to paint/seal the inside or just run it raw?

I was looking into this stuff last year, there was a ridiculously good channel on youtube called "The Astro Way".

He had up to 16k subscribers, the channel was starting to blow when they pulled the plug on it. I knew it wouldn't last, he showed everything from multiple, MULTIPLE mushroom teks to processing ayahuasca and extracting DMT.

All this in super detail without saying a single word, just annotations where needed and while playing various vintage interviews with pioneers like Paul Stamets and Terence McKenna. I don't have instagram but he could probably be found there.

Edit: Yep. Check this guy out. His channel was amazing. Login • Instagram

Don't mind you sharing one bit.

@manthatreeksis the box I built. I did seal it both inside and out. All seams caulking and then the whole box was painted with Zinsser, which I had to let off gas before firing it up.

Ironically the prefilter box was never constructed and I simply lay filter material over the top to keep just from getting sucked inside.

It is sitting in my culture room with a microscope in front of it since the scope is too big to fit inside my new hood

That was gonna be my next question about the off gassing. Cool man. Yeah, I didn't really finish before I went off on the youtube tangent (apologies) but I was looking into this a year or so back, you know during Covid when everyone was inside looking for new hobbies, lol. Anyway, I'm the buy once cry once type and like to have the proper tools for the job, so once I learned laminar hoods tilt the odds of success, I figured that would be the first step. Then came the indecision on what design or plans to use, the supplies sky rocketed and the idea pretty much died.

I'm still very much interested, not just in "tripping balls" but especially in the micro dosing aspect... I've been told it can be life changing.

Watched a lot of his stuff,. I like listening to the audio of his videos as much as learning from the videos myself. My first Martha was built using his examples, and other research. He is on Patreon still sharing

The concept is simple. Build a box with a 2'x2' INNER diameter. That filter is exactly 2'X2' and slips right into place. The fan is inside the plenum and pushes air through the HEPA filter. The fan is connected to a speed controller. Plug her in and turn the fan speed up until your flame bends.

Fan hole still 6in from back? and the 1x2 set back 5 3/4in in the front..ie width of filter..kind of acts as backstop if recall.
