If you don't have an existing circle of people to get proven cuts or seeds, usually in a police state where paranoia and security are the only way to survive- it could be difficult. For the famous ones if any delays getting...the easiest way, by far to get proven clones...
!Most importantly, for gg4, ogkb 2.0, etc support their founders (Josey and Chunky, etc)! And also support their original intentions.
For all the rest:
Plan a week vacation in Cali, avoid the lines by not going at the height of the outdoor planting season.
Book the hotel.
Generate a pay stub using address of your Cali hotel using https://realcheckstubs.com/
Print the pay stub showing the hotel address for at least 30 days prior to your trip. If you have a cell phone, depending on the carrier you may also just change your mobile phone bill online to reflect your new Cali address, and print it. The paystub method is more reliable though if you're considering Oregon or Colorado also.
Research reputable clone distributors and you will see how they make drops. Some dispensaries announce drops on Instagram.
As soon as your plane lands in Cali, Rent-A-Car and drive to the closest DMV. All you'll need is your out-of-state license and the paystub and score an ID card for State of California.
Find the closest MMJ doctor and tell doc you have a problem with stress. He'll give you a recommendation for about 80 bucks. The receptionist will need to see your ID card.
Build some clone shippers using empty soda bottles.
"Go to the weed store"
And meet any locals you trust already.
When you get your fully rooted cuts, ship them immediately with fast shipping to the safe address with somebody who will be ready to receive them and put them under a light in quarantine and treat for pests accordingly.
If you can source the true origins of the cut- Pay it back by contacting that person and donate to them with PayPal or whatever. The Honor System is at work here. It's the right thing to do.
Best of luck, be Careful, and have fun trip!
