We have an FFU that was installed in a ceiling with its back exposed to an attic, where it was used for a couple years and then not used for 7 years. Is it salvageable?
I was thinking about changing the HEPA filter on it (in addition to changing the pre-filter of course), but it doesn't seem like the FFU is made to be taken not made to be taken apart easily.
What is y'alls' protocol for FFU maintenance and for changing or not the filters?
Do you ever perform a test of the HEPA for leaks?
As always, thanks a ton for the help!

Hello fellow heathens!

I'm curious about proportional injectors for peroxide in my misting system. I currently use a 55 gal drum reservoir that feeds into a HART setup. I have been using bleach when filling the drum from an outdoor hydrant to keep the water from getting too funky. I'm curious about using peroxide as an alternative treatment.

What product/injectors are people using to inject into misting lines? I'm familiar with dosatron style fertilizer injectors but they require higher flow rates. I know I can just add peroxide to my large reservoir but I'm curious if anyone is injecting the peroxide into the misting line as it is humidifying. I've heard mention of peristaltic pumps but I don't quite understand the specifics around them.

Thanks!

Hi everyone!

I was wondering if you had any tips about placement of the CO2 meter (yes, I listened to your advice and got one finally!) I'm experimenting with different positions, so far chest level at the back of the greenhouse seems to work well but maybe you have some pro tips that could be useful!

Thanks for all the content, it's so dope.

Hey again guys! I just watched the short clip on your YouTube channel on the King Blue from mossy creek.. I have been growing it for 3 years now. Currently I have 2 accounts buying 80lbs a week of them in total. I’m sure you know, but that hybrid is even more prone to blotch than a normal oyster.. I noticed in your video’s description you mentioned to cycle different strains to reduce blotch? For example, the king blue will kill it for a month straight, and then it hits the fan for a few weeks in a row with blotch and messes up my weekly orders…. Per say if I cycle the king blue out with your Blue CNS like every 3 weeks that will help keep the blotch down??? Growing 80lbs a week of one type to meet my accounts orders and have it shit on me really hurts!!!

Thank you! Been learning so much from these deep dives and this community🖤🤘🏼

I’ve never cultivated Lions mane, but one visitor to my farm asked me about the possibility of cultivating them on logs (wood logs, not the substrate ones hehe).

I know it would probably have the same pros a cons as shitake, but I’m really curious to know if anyone has ever seen or cultivated lions mane on logs!

I'm curious what everyone does/recommends..

I would like to follow the recommendation of using the leading edge of plates (as stated on the pheno-flicks) to inoculate masters. However, due to time demands, I have not been able to time my spawn production so that I am ready to transfer when the plate is at the perfect point (the mycelium is 1 or 2 cm from the edge let's say).

In that case, os it better to fridge the plate when it has myceliated maybe half of the plate and then take it out 1 or 2 days before I will transfer it to grain (so that it is active and growing) I can still use the leading edge)?
OR
Is it better to leave it in incubation, and use it even a few days after it has covered the whole plate, but avoid taking from the edges that have a risk of being contaminated?

Really appreciate any inputs, opinions y'all may have.

I am looking for a solid Oyster Mushroom culture to grow.  Can I buy a culture from you or do you have a recommendation on where to buy the best quality liquid syringe cultures?  Appreciate it.

We have learned so much from your podcast and Deep Dives. Our blotch struggle began last year. By applying your methods we were able to eliminate it....so we thought.

We have a shallow well and blotch has reared its ugly head again this fall (same time last year blotch appeared). We have added U.V. sterilization and filtration system which has helped immensely. The water table fluctuates and filter maintenance fluctuates with it. Water table is low right now, changing filters twice a week. Still problems with blotch. 

Watched Blotch 2. Put a reservoir with peroxide 1/10% concentration of hydrogen peroxide and noticed beneficial changes almost immediately. In my research on well water filtration I came across this video. This is excellent information on hydrogen peroxide treated water.

I hope this helps anyone. Keep producing content!!

Just wanted to say how much I have benefited, learned and improved my op from your content, both on the podcasts and the deep dives. It's a pleasure to contribute and I will let others know how much the deep dives are worth it. My knowledge has increased significantly and I have been able to problem solve and prevent future problems. Also came at just the right time as am building a new lab.

Keep doing the good work of contributing to building each other up! 

First - I love HE-CNS...  it produces MONSTER yields for us.  That said - I HATE it (and can't grow it anymore!) because it bruises so easily (green bruises where harvested by hand even when slightly rough).

Does anyone have any experience with this?  Also, how to avoid this?  It's just too much work to explain to chefs and at the farmers market.  Too many phone calls telling us our fresh lions mane is "green molded".  Any help to let us continue using this variety would be greatly appreciated!!
