Lions Mane Buckling (I think I fixed it?)

I can't find the post I commented on about lions mane buckling on the block and sometimes completely falling off, but I noticed that once I nerffed my Rh out of frustration things dramatically improved. I know that if my exhaust damper fails then dirty air will also cause buckling, this is leading me to believe that bacterial stress will cause buckling in addition to possibly other things.

I started cutting my lions mane blocks where there is already nice, thick mycelium near the top to see if part of the problem was in that first week of pinning. Cutting in the denser part reduced pinning time for me by up to 5 days and seemed to prevent bacteria from taking advantage of a cut site with less mycelial mass.

I'll hopefully be submitting a grant for a Hart/POLA system so we can move away form vats of stank water sitting around! This should dramatically help with buckling. Anyway, idk if this was helpful or accurate. Feel free to chime in with your own observations and opinions!

Suuuuuuuup.

This is my first post here (I lurk a lot on forums, please accept my mushroom beebs as tribute). I'm working on possibly getting a HART Ultimix system installed via grant funding, however I'm wondering how much of a difference there is between the $100 brass solenoids and the $17 ones? I can venture to guess quality, but can anyone describe what the weak points of a solenoid are? I have limited experience installing solenoids.

Butforealtho - I don't want to clean my hydrofoggers anymore lol

I'm about to watch the coroplast HRV podcast for the 5th time cause I'm trying to cook up a way to integrate them into my warehouse build. I mostly understand it, however I get a little confused with how the air is being pulled in from the bottom as well as being exhausted out the bottom. Is that bottom 'spore dump' zone walled off below the vent to keep the air systems separate?
