They are at 40 days today and I've yet to up-pot. And based on the amount of water they're drinking (about every three days), they're not ready for up-pot.
I'm thinking at least another 10 days before I'll consider up-potting and that puts me at day 50.
Once I up-pot and give them a few days to settle in, I'll be at, say, day 53.
From there, I want to take advantage of the wider diameter of the larger pots to open the plants up by tying down branches further out. Two weeks of doing that will put me around day 67.
Then, if the plants agree, I can then think about flipping. Day 70 is a safe bet.
Thanks for asking
@Carcass. Now I have a documented "plan."
