I feel like this thread needs a reply to the op.
I am no expert by any means but I believe as being a customer of theirs and knowing enough how to grow and about Cannabis, that I can explain some of their technique.
Other than what others have already mentioned about their lollipop and feed techniques, I think their use of vpd in growing and drying is a big factor.
As Ivan says, the basics are dialed in. Any good farm is going to have this and anyone 10+ years of growing big scale is going to have that shit dialed in.
Their method of dying on the vine and whole plant hanging in 60/60 means that they are curing as they are dying, meaning canabalising of sugars into more THC. I am a believer as I smoke it.
The highs are consitent at 3-5 hours. Their herb is always fresh, burns to white ash, is clean as hell, and has amazing pheno traits. Their Orange Cookies smell and taste like the real thing. Their Wedding Cake is unreal, funk and sweetness with a frosting taste.
They mainly do hybrids which may attribute better to their one node technique. They are very much Nor Cal and San Fran genetics. They use that TK a lot as well as any Cookies. They do a lot of pheno runs from my understanding, and some take a couple of years, but they always have new shit coming out, so they are well organized.
Their collective can be a bitch, but people will wait for 2+ hours with a smile on their face to get this herb. I get an OZ every time at 275.
The proof is in the herb. It seems like it never dried but never stayed too wet. It is perfectly wet and sticky, but still burns easy as if it was dry.
I think this is because of the dying and drying technique. With the proper VPD you will not get mold. The moisture in the air will not be as airborne with an extremely cold drying temp, so the humidity can stay higher, and thus the drying is slower so that they are cured all the way, and not drying them out and then attempting to reinject the humidity in a jar.
I believe the trick in drying is hanging high. This keeps them from being closer to the heavy moisture which is staying much lower at the low temp. My 2 cents.
Peace.
