We immediately trim on-site and place the buds into vacuum bags for clothes for transportation. These bags with a pump are very convenient; it's best to use several bags: for example, fill a regular thick black bag with stuff, and then put this black bag into a vacuum bag to avoid punctures from branches.
For working with the buds, we got "snippers" — as it turns out, these are very convenient scissors for our task. It's a real pleasure to work with them.
The density of the buds is generally good, considering that this is wild outdoor cultivation in a fairly humid climate.
P.S. After 4 hours of trimming, we were exhausted and just ended up removing the fan leaves and non-sugary leaves.
