I use a plastic box about 13 x 7 x 4 inches from Home Depot and The plant is trimmed placed in the box to dry for about 5 days agitated periodically for even drying. At the end of five days the knobs are pulled off the stem an slightly trimmed and allowed to dry for a further 5 days.
The relatively dry material; is placed in a liter jar about 60 grams per jar and pressure cooked for 2 hours at 15 PSI. This is 240 F for 2 hours which effectively decarboxylates marijuana.
I make olive oil and/or heavy cream infusion and ingest a small amount a teaspoon for effect. I do not smoke.
