I guess it's possible I may have given up too fast. Their was new growth on all of them but more leaves/stems fell apart faster than it was growing and I felt it wasn't worth it too keep

If there is new growth, they would most likely come back. Sometimes the plants are grown out of the water to get them started faster at the nursery... of course not all plants can be done this way but the "air grown" leaves will not continue under water so they die off and the new growth that has started under water will flourish.

I have seen some at some of the big box pet stores, never bought any though, that are kept in the bag or container not submerged... those would likely go that way.

What plants did you get? Stem plants tend to adjust and transition better if left floating (as long as your current isnt knocking them around and dragging it under).
I generally float weak stems until I have a significant length of healthy shoots to plant. Using this method, some glosso I floated managed to transition from emmersed growth to a low light low tech blackwater tank(bowl). By then I had forgotten about it and somehow it had rooted itself (maybe something knocked it down?) under a piece of cholla wood with next to no light. lol

The only plant that I've failed with this method so far is elatine triandra, I think it's partially due to it being a nitrite hog root feeder and also tendency to melt when touched.

In addition to what has been posted by others, there is also the "rest" period that all plants go through, though stem plants show this a bit differently due to their method of growing. But right now, the Pennywort in my tanks is not doing well at all, and Ihave had this occur over the past years from time to time.

What is the GH of your water?

Apologies if this was mentioned and I missed it, but what type of filtration do you have? If the surface of your water is very turbulent, some floaters - like frogbit and WaterSprite - won't thrive. I was able to somewhat get around this by creating a 'corral' for the floating plants, an area where the surface of the water was calm. Duckweed doesn't mind anything much, though - and it will most certainly thrive in the lighting you have, provided you can keep it out of the filter (really shouldn't be much of a problem unless you have a HOB, in my experience)

Just to add. . . I have a tank with a single T8, and I'm really unable to grow most stem plants in there - especially not with the floaters adding more shade. I also have soft water, which can come into play, depending on the species. I have had very good luck with the lower light plants, crypts, anubias, java fern - they have continued to grow and thrive, despite the floaters further reducing the lighting to the bottom of the tank.

It's a HOB but I've created a baffle for it plus the flow is adjustable so their is very very little surface movement...and to answer your question Byron on my GH.. I believe it's in the 280 range

That equates to 15 dGH which is certainly enough for the hard minerals so that is not an issue. Another comment, most of our aquarium plants are soft water species, and these will do OK in harder water but they may take some adjustment time.

On the light, I agree that a single T8 tube is going to be very low for substrate-rooted plants. It should work for the floaters though.
