You are why I invested in my flow 48 Gary, thank you for all the education over the years.

My FFU doesn't have proper slots of a place for a pre-filter, so I found a linen bag (like for bras and intimates) that is just a bit bigger than the intake. Been working pretty good. It doesn't stress the fan too much and cost like $2, so I'll probably just chuck it...or wash it. LOL Thanks for the video. Always some good stuff.

Great to see you! I have your yellow oyster and chestnut mushrooms fruiting in my grow tent right this very moment.

@Artiquesols 5 месяцев назад

Thank you for always sharing your information with us. Im a very talented but struggling mycologist and your techniques have guided my to personal success. Subjective success but thank you for being someone to look up too in the field.

The original blue pre-filter for the flow 48 a washable. I just take em of and use a pressurized stream of water and spry them off from the hepa facing side. Let them dry hit em with iso and reinstall. You can do this multiple times and I've had the same pre filters for 2 years. I'm going to replace them this next time because the weave will get weak eventually, but the blue hvac filter is the way to go in my opinion.

@FreshfromtheFarmFungi 5 месяцев назад

I ended up scrapping mine and I like the convenience of these ones I suppose I can wash them but this method works well too - thanks for the tip!

Woild you have a lab specific air compressor for cleaning your ffu?

@LarsLarsen77 5 месяцев назад

I built mine out of a 10"x10" filter from meyers mushrooms, and my prefilter is actually a can carbon filter which doubles as a stand for the fan. All I have to do is order a new cloth prefilter for the carbon filter and I'm good to go. I can easily see how dirty it is at all times so I dont even have to check it. The only problem is the 10"x10" filter needs a tiny bit more back pressure to produce laminar flow so I still need a few generic air purifier prefilter sheets inside the cabinet too.

nice!

Great video! Question, I have a very dry climate where i live so there is a lot of dust in the air, I one is not running the hepa 24/7 would it be a good idea to when not in use put a plastic cover/curtain in front of it so that dust doesn't settle on the mesh in front? for use i would just roll it up.

@FreshfromtheFarmFungi 5 месяцев назад

yes that is a good practice to have - it is annoying for me because I use mine every day but makes sense if you only use it once in a while

@thematrixcentre 5 месяцев назад

Any advice on what to look out for while buying a hepa filter for diy flow hood. As always it's very informative watching you video. Thanks for everything 👍👍👍

@FreshfromtheFarmFungi 5 месяцев назад

I think I would first start with the size - I prefer lots of headspace for inoculations, that might increase price a lot but it worth it. Then I would get at least a mid-grade quality filter - the plastic ones are good enough but the metal ones will last longer (they can get damaged easily though like the fins on an A/C unit). I never built my own but I have seen many people make the mistake of putting too much time and energy into a 12” x 12” flow hood and then in 6 months buying a 2’x4’ - hope this helps! 🍄❤️

@killerkennyas 5 месяцев назад

@FreshfromtheFarmFungi i agree..start w at least a 2x2..I built my.first 1 like that and now have that and a 2x4..both homemade..my bigger ones Fan went out a week ago so I sacrificed my smaller ones fan..I cleaned really good while apart and then made plates and let sit for few days under the hood to test the efficacy of it.

Love the videos brotha I have the same double stack flow hood but it doesn't blow that hard i wondering if the filter is clogged or something the fan looks like a turbine if you have any info that would be awesome thank you

@FreshfromtheFarmFungi 28 дней назад

yes I had to modify the intake in the back by caulking and adding some foam so it had better suction I totally forgot I did that years ago ha

@freegreenguru57 27 дней назад

@FreshfromtheFarmFungi ok I'll have to see if I can fix this problem

@Goofykatze 5 месяцев назад

Since we want the particulates removed from the filter, isn’t it counterproductive to use the blower to blow them to the „wrong“ direction? In to the filter?

@FreshfromtheFarmFungi 5 месяцев назад

no, once the filter is turned on an left on it will push anything in the normal direction - the point of this blowing is to remove the larger particles that built up along the edges and got stuck in the screen.

Sometimes before use, when cleaning hood surfaces, I spray the filter lightly with the alcohol. Is that bad? Why?

@FreshfromtheFarmFungi 5 месяцев назад

it should be ok. Alcohol is a disinfectant so it should not promote microbial activity and evaporates quickly. I mostly was talking about accidental spills in the video - this can cause issues if it’s not addressed immediately- it can clog the filter, which in turn can promote microbes to survive the desiccation and worst case start entering the clean system.

@willjames5243 5 месяцев назад

Thank you Gary! You're an inspiration to me in Virginia!

@willjames5243 5 месяцев назад

You leave your hood on all the time?

@FreshfromtheFarmFungi 5 месяцев назад

yes

@willjames5243 5 месяцев назад

Thanks Gary. I sometimes worried about leaving it on for only 24 hours when I wanted to maintain surface sterility on sub bags, plates, jars, etc in the interim til I can find time to innoculate. Thought I'd be using up the expensive $900 filter too fast. But at 5 years of continuous use, and me not running continuously but only for 24 hours or 36 hours at a time, then I could get 10 or more years out of it, which is cost manageable for sure.

@LarsLarsen77 5 месяцев назад

An air compressor produces a ton of water. Air brushes have a water trap built into the air line because water causes obvious problems when mixed with paint. A regular air compressor doesn't have said water trap.

@FreshfromtheFarmFungi 5 месяцев назад

yes this one has a bleed out valve so when you’re finished, you can let all the air out and towards the end sometimes there is a few droplets- nothing that would cause any damage
