It's a big enough problem because the pressure across the filter face is compromised. So there will be some lower and higher spots for sure now besides the unfiltered air right in front of it.
Usually you try to patch the hole with silicone or hot glue on cool setting but the metal protector makes it hard in mini-pleats. See if you can plug that hole up with silicone best you can and you may be OK. But you may not be able to seal it enough and still have dirty air blowing from the hole. Try it out.

Nah, it won't blow dirty air from the hole. That is NOT the concern. If you're using a proper HEPA filter, then it is plenty thick to still filter the air. The concern is that it may cause enough turbulence to disturb the laminar flow, but I am quite certain that tiny little hole will not cause you too many problems, if any at all.
I personally would purchase a used flowhood with that minimal damage, and wouldn't bat an eye.

No offense but you don't know what you are talking about the filter is less than 1/4 inch thick.

Oh wow, I guess I may be wrong. I didn't realize that they made filters like that.

Yeah it's just a thin sheet but then it's accordion folded so there's lots of surface area to create the static pressure effect. Makes it so a 6 foot long filter fits in a 4 foot long space or w/e

That's interesting. It seems like a filter with that design wouldn't last as long as a traditional 6" HEPA filter. Good to know.

That's also basically the same way that 6" metal separator filters are made but they are very slightly thicker
All of these HEPAs are accordion folds of a thin continuous sheet and they are super fragile.

That's right. It's more like 282 sq ft in a 4 sq ft space with the 12" HC packs which is exactly why you should avoid 12" packs and get a 6" pack. 6" SC packs on a 24x24 have 77 sq ft.

Any reason you haven't lined up a row of open plates in the flow to see if they're good?

That's a big enough issue to cause contamination, it's similar to the problem a few of us had with the ffu from China. Mine had microtears that were difficult to see but plates got contaminated, when I replaced the hepa my problems were solved

It's probable that they are all made in china. Not that there's anything wrong with that. The shipping charges must be a beast!

Used Envirco Mac 10

says made in China

Would be a great project for build it DIY. top line motor, blower wheel, speed control, and switch can be sourced for under $300. The rest is just a box and filters.

Lots of them are constructed in the USA maybe they outsource some of the parts but mine came from a company in the states that builds them here.

Terra are USA made. Not that it really matters too much China can make some quality stuff along with crap.

Yeah it would be a good idea to make them locally to sell. It's all HVAC components. Would be easy enough to get a local sheet metal fab shop to build the box.

I wonder if you could have a fan moter box with a prefilter below your table, cut a hole in the table, use ducting to run the blower up through the table to connect to the bottom of the filter box. 2 separate pieces to move around easier if ya need. Still easier to just buy a ffu though lol

I've thought about exactly that! The thing is what's convenient to our resources and skill level. A FFU is a ceiling unit being used tabletop for laminer flow, generally speaking. It's appeal is the motor and fan is contained in the unit.
Personally, now that I've studied the matter a bit, I prefer the idea of placing the fan unit on a shelf above the filter box fed by a duct.
I'm still exploring how I will approach the build.

For anyone that has recurring bolete mushroom patches, do I just spread compost around after harvesting to feed them? Or is there something else I can feed to help bring more flushes?

Are you using an SAB, a flame for scalpels, and ISO alcohol to spray down things (you should, but don't light yourself on fire. Don't use flame inside SAB).
Are you using a heating pad (you should NOT, plus it's summer, or are you on southern hemisphere where it's winter?)
Did you start with a spore syringe, swabs, or spore print? Did you go straight to grain or to agar first? (latter is better, if done right.)
welcome. Read the link in my sigline too "things I wish I'd known...")
How slow is it growing? These jars should probably take 2 to 4 weeks to fully colonize white in the summer. ...
Hiya,
TBH I dunt rilly keep notes nor take many pix (p'rhaps I should start!). I started with a clean agar plate. I diced up some lumps and put them into MEB - that grew well. I made up my compost verm mix the same way I did for my abort tub, that I posted about earlier. I also sterilized some popcorn in some jar at same time (with no real intentions for it!) - see pix. I shook up the MEB (30ml Universals, lids tight) to break up the clumps and used a sterilized syringe to inoculate the Tek jars and the popcorn. I just work on a clean bench next to flame, not as good as a Bunsen, but it seems to work. I then left Popcorn and Tek jars in a closed room for a couple of months - sorta forgot about them. I just checked me uploads here an saw I got a pic of the same jar(s) uploaded about a month back... I just checked the temperature in the room ~80°, but prolly v dry. Given all the Tek jars are the same, and popcorn is showing no contam I'm guessing it just got too dry?
I'm not rilly worried about it, and in no rush - I prolly still got about 35g of shrooms to go through from my first tek (using brf & verm) - that should keep me going till i get the next one right. At the moment I'm just playing around and learning and now I know what "mushroom piss" looks like 
thnx
