Just hung two today. thank you

@retro I don’t see cannabis written anywhere on that chart. This may be helpful with some other crop like wheat or corn but you will ruin your harvest following these parameters for cannabis.

I wish they had a love ❤️ ❤️ for comments. Because that is awesome info. I see 60/60 didn’t make the cut

@senorvertoyayubi I’ve done all the drying experiments as a teenager. My first successful harvest was ruined for having humidity at 70F/30% because I wanted it to dry fast without knowing anything about the process. It took several crops to get a smokeable harvest when I had no idea what conditions were needed. You were not going to read them in any grow book. I eventually ended up at these parameters. I shared my SOP with the DGC over 10 years ago and I’ve noticed many use it commercially now. Slowly bringing RH down over several weeks is how you produce the highest quality possible.
Week 1-2: 60F/60RH
Week 3: 60F/55%RH
Week 4: 60F/50%RH
Week5: Seal in container.

Allison wants to ruin for crop it seems. these are not the conditions for drying cannabis. Follow that chart and you’ll have some really shitty weed. I often have my dry room under 60F but the RH better be above 50% or It’d dry in a few days instead of a month and be straight hay. I will call you ignorant as shit if you follow this chart for drying cannabis and I really don’t want to do that.

Thank you jmystro 60/60 is what i usually do for 12-15 days then trim and jar durping several times a day for about 7 days then jarred with humidor pouches for two or more weeks.. Was just questioning humidity if temp little high or low would you try to adjust humidity i don’t ?
