The transition to vertical farming, would IMHO, allow regular farmland to transition to forest — which would help offset carbon — and reduce the cost for regular farmers bc the crops would grown in a more-controlled environment. So, what’s the holdup?

Vertical farming is much more expensive than traditional farming. Most estimates have it at ~3-5x as expensive as traditional farming. It also requires more power usage per acre of growing space than traditional farming does.
Some crops are just not suited to vertical farming as well. Think of how tall corn grows; that kind of crop isn’t exactly ideal for a vertical farm.
This is the reason that vertical farms have largely been growing plants like lettuce that are quick to harvest, low to the ground, and can be grown in high densities.
