What if we took our MycoPunks Flow unit, embiggened it, and then made the filter even better? Let’s see…
We’ve got the really cool Mini Flow for the hobbyists at home who are getting serious about mycology, we’ve got the 2x2 and the 4x2 in the middle end of the sizing scale for people who have a bit more dedicated space to spare, and then we’ve got this fuckin’ behemoth, at 4x3. We put one on its end in the warehouse, came back after lunch, and there was a crowd of apes around it, straight hootin’ and hollering, getting smarter by the very second.
It’s big as heck, so the fans have been upgraded to make sure it’s pushing enough air through, and instead of the already-amazing H14 HEPA filter, it’s got a U15 ULPA filter as standard: this means that it filters out 99.999% of particulates that are 0.12 microns or larger. That’s so close to being everything that it is just basically everything. You could barely get a bit of submarine billionaire through that.
If you’re serious about growing mushrooms and getting into some proper lab work, this absolute unit of a unit makes sure that you’ve got a massive clean air space to get it all done - that extra real estate is a luxury to have if you’ve got the room to fit one of these nice big 4x3 Flow units in!
