This is a beautiful development!
However for 3.5 months one could achieve a much faster growth. If you had flooded the soil with water once a day and drained immediately you would have had explosive growth. What we see happening here in 3.5 months would have hapened in less than 1 month. But the flooding would be a daily chore.
I hope the transition to fully submerged goes well! After all the entire idea of a dry start is to give the plants a huge boost - they start with established roots.
I too think you should start the CO2 from the very beginning. But not 30 ppm. The reason being that I believe more in the filtration as a way to keep everything in line. Neglecting the filtration and compensating with fertilizer or other things is counterproductive to me. So try to not suffocate the bacteria in the filter by pumping 30 ppm CO2. Do pump CO2 from Day 1 but not at the maximum level.
I see you have a good size filter. The best approach would be to seed this filter beforehand - hook it up to the new tank only after it has been operational for a few weeks.
Amano has an interview talking about a particular tank in which he did not want to have any issues. One of the things he says he did was exactly that - to run the filter on another tank for a month and then use it on the brand new setup. The idea is easy to grasp. But note that Amano says that the tank used for seeding the filter was established well and very clean, no alagae of any kind.
I think it' would be beneficial to use a seeded filter and at the same time not to suffocate it with a lot of CO2 in an attempt to provide the plants with the maximum amount of CO2.
