There is no reason not to add the plants the same day you add the substrate and water. This is assuming you already have the lighting you need, the fertilizers you need, a CO2 system if you need...

Two inch diameter pipe is not big enough for that large a flow rate. It is more suitable for smaller filters. I suspect that if you used 3 inch diameter pipe it would work fine.

Because DIY CO2 is never as consistent as pressurized CO2, I suggest that you limit your lighting to low to low-medium light. This will make any BBA problems be less severe than they would be with...

You have more than 50 PAR light intensity, but no fertilizing and no CO2. The plants are being starved, so they can't grow. Usually when that is done, the fastest growing, most forgiving plant will...

10 ml is the Seachem recommended dosage for 50 gallons, if it is a daily dose. If it is a weekly dose, it isn't doing any good as a source of carbon, but it may help keep algae under control.

That is because the typical water pumps we use don't generate much pressure. They just move lots of water. When you restrict the outlet flow the pressure doesn't go up, the flow rate just goes down.
