Jan 17
Cut down the 2 GSC's the evening of day 75. They were showing sufficient amber.
I built a prototype slow-drying chamber our of some computer fans, storage bins and travel humidifiers. It's working well at regulating the humidity in the box, i can set it at 80% and it hits that easily. I started at 80& for the first day, then 60 the next day and now I have it at 55% where it will stay for a couple weeks.
The main idea is a two chambered design which disperses the moisture really well, with the sensor mounted in the top chamber with the weed controlling the humidity production in the bottom chamber. My RH in my house is in the 20's in the winter, so some sort of sealed chamber and humidifiers are mandatory. I am loathe to blast humidity onto a bud and see it rot, so proper moisture diffusion into the air is very important. Moving the air without blowing directly on a plant is also important, so the lower fan blows into the chamber, mixing the moisture and passively forcing it up through the holes in the lid. The two boxes are not perfectly sealed so some humidity escapes and some drier air gets into the top chamber. The exhaust fan on the top of the top chamber is on the dehumidify circuit of this inkbird controller, and also adds some airflow as the weed loses moisture.
If it seems to work well I will build a more robust and finished version with whatever improvements I discover it needs in prototyping (odor control, locators for the bin to bin connection, fit on a shelf somewhere, etc). I will need this box to function essentially 24/7, cutting down a plant every two weeks.
I am a tiny bit worried there is not enough actual airflow arround the buds, so I will be watching for rot like a hawk. I can always add more fans but in a small chamber its hard to not have them aimed at a plant. This is the first time I have tried this small scale drying with the proper environment in mind, and I did not find any really concrete examples of similar constructions online. It seems like the Boveda moisture packs have even taken over the Cigar industry for maintaining humidors and such.
Both the BerryBlues are looking nice, with the younger one looking very chunky and well filled out. Both are showing some purple. The temps in the tent get down to 18 C for four hours every night.
My Purple Punch and Purple Lemonade seedlings are doing great! The New Generation is coming! Next to be planted will be a FastBuds Blackberry on Jan 31! I started individual journals for the different strains so I can give data to the site properly and qualify for contests and such. I will continue to post pics of the whole tent here and updates on the perpetual cycle as a whole, but detailed tracking of the individual strains will be in their own journals.

BerryBlue is looking good, the Purple Punch is an incredibly strong seedling, and the Purple Lemonade is a happy sprout. The weed drying box is working, some issues with condensation in the lower chamber so I turned down the humidifiers and added a little piece of wood for them to sit off the floor of the bin. The leaves on GSC 2 are just starting to be crispier, but are still malleable. It's certainly different drying on this scale, you can examine 100% of the product closely. I think something close to this concept will work though :)
How do people do time lapse with hid lighting? Do I need to set timers to turn off hid, turn on fluorescent and then take the picture? Is there a filter I could buy that eliminates the horizontal scanning lines?
