Well, some folks seem to think these are hard to grow, I call them weeds:
ADA aqua soil + EI dosing.
No powersand, not EC, Green gain, Penac, none of that.

More photos

TF grows about 3" weekly
Erios, well, they are weeds, 2-3" and many branchings
L pantanal, this is a weed, grows 4-5" a week
I tossed it out due to weediness.
I keep a small piece now.
L cuba grows 5-6" a week, grows more in a client's tank that gets basic EI.
T manaus grows slower, about 1-2" a week, it's a nice plant.

Even Crypt nurii does well.

I'm not sure why folks think the ADA liquid ferts are blessed with some magical properties. The Aqua soil is great stuff, but IME, the ferts are not particularly great in terms of growth rates, which is what plant preferences are defined by.

Clearly the color and tougher species do very well with EI and ADA AS alone.
Slowing things down is easy, you reduce the lighting.

Instead of 4" a week, you get 1-2"

I've also been very agressive in uprooting and moving plants around, seems to work very well, like gravel in terms of mulm, algae etc.

I'll measure the contents of the liquid ADA fert line later this or next month.
Then you will know what is in them and will be able to DIY them. You cannot hide the chemistry.

This is impressive Tom,
To show my ignorance, which plants are that?

Not Tom, but I believe L-R in the first pic is Tonina Manaus, Ludwigia inclinata var verticillata "Pantanal," Eriocaulon setaceum, and Tonina fluviatilis. These are all accepted as high difficulty plants by most of the planted tank community.

Or "weeds" by me:-)

There's no secret, I tell folks how to grow this stuff.

crazy colours!

Well, folks think that EI is so bad etc and needs fine tuned, that maybe for most cases, but at high light, CO2, it seems to do about anything you can ask for.

Seems all anyone respects is a pretty pic of lots of weeds etc.

So there it is

With high light and fast growth, does the distance between the nodes increase? I like stemplants (weeds) to be abit bushy if you know what i mean

No, spacing is fine.

High light I've never associated with internodal spacing. Nor low light.

I've got some extremely wide ranging client tanks, going from 1.5 w/gal of NO FL's in a 28" deep tank to about 8-9w/gal in a 48" deep tank to a 4 w/gal in a 28" deep tank to 2.1 w/gal in 22" tank, to 5.5 w/gal in a 16" deep tank, to 2w/gal of NO FL'2 in a 16" tank.
