I don't know how accurate that "probe" is that you spoke of but I suggest you look
at the T5 chart on the link for the PAR value.
Anubias and Java Fern can grow a bit faster when subjected to high light, but are
low light plants. Most low light plants fit in the "slow" growing category.
Even med growth rate plants get GSA on the leaves in high light because their leaves just last longer than those of fast growing plants. Some leaf loss is common in the first
month after planting any plants.
You might get some usefull info from this link.
Anubias and Java Fern have what looks like a runner along the bottom of them which does not like to be planted. Only the roots which hang down from that are supposed to be planted. Those plants are often tied on wood/rocks instead of actually being planted. Those two types would get less algae if under the shadow of the other plants when they grow out more. Anubias Nana might be a better size for that tank.
The Jungle val will end up being too tall I think, for that tank.
Really, the hardest part other than the light requrements on plants is picking ones which have a good size for my 10g tanks(2). And my not having enough patience to
let them grow a bit without messing/w them...LOL...
