Great idea, I'm certainly going to give this a try! Your Trop Cherry looks incredible, well done. Here's a picture of mine around day 35ish, hit a few branches with a selected BOG Grape Punch male.Amazon is where I got em. I searched something like “long rectangular boxes”. Use some bubble wrap and duct tape to secure the plant to the inside of the box which starts out flat. You then rolled up the box and slide in the tabs to secure it and you’re good to go! Plus the added pressure from the bubble wrap around the solo cup when you fold up the box makes it even more solid. I developed this technique and I’m now 100% confident they can be thrown around and ride upside down and arrive completely intact. I’ll even bubble wrap the entire plant when I have it available.
