That's what I figured, I'm somewhere right around 20-23 micromols, do you think most of these plants can grow, or even thrive, given the right nutes, but no co2?

It will start to grow long roots up the stem i have a few sunset hygros like that now sorry i first gave the wrong info.
Floating plants don't know where "up" is, so they tend to grow in a gnarled form, twisting, looping around, etc. Then when you finally plant them in the substrate it takes quite awhile for them to begin to grow up instead of in random directions.
You normally plant stem plants with no roots on them. They are just cuttings. You should poke them down into the substrate as deep as you can, preferably at an angle, so they can't float back out. This is easy with long tweezers.

Hoppy are you saying that if I buy a stem plant that has roots I should cut it to a bare stem and plant it?

No, I'm not saying that. Most stem plants are cuttings from other plants, so they are rootless when you get them. Most of us tend to prune our stem plants and plant the cut off parts to get a denser growth of that plant, or to get rid of the bad looking base of the plant. There really isn't any reason to plant rooted stem plants, since they quickly send out new roots if there are few or no roots already there. In natural settings many, if not most stem plants reproduce in part by shedding the top part which floats away and eventually roots itself back into shallow water. Just think, the stem plant cutting you get may be a piece of a 100 year old plant!!:icon_smil

Hoppy is right, but I am not sure he answered your question directly.
If I do get stem plants with roots, I do cut most, if not all of the roots, off before planting. The existing roots will most likely rot anyways.
With rozette plants like swords, I trim the roots to about 2", just long enough to keep the plant in the substrate.
The above does not apply to rizhome plants like anubias and ferns and I tend to leave the roots of crypts alone.

Hoppy and OVT, thanks for clearing that up. I was worried that I was supposed to cut my stems bare before planting

I'm loving this list- I just set up a low-tech tank and I'd love to add more than the crypts, vals, and anubias nana that's in there now. However, I'm thinking I should've added soil. Do you have any suggestions for fertilizing a simple gravel-bottomed tank?

@dpod: many of us here don't use soill in our tanks. Root-tabs are your friend!

Approved?
Is this list still considered a good directory of plants to grow in low/med light with no co2?

The list should be seen as an opinion, which is not necessarily correct. For example, HC- Hemianthus callitrichoides will not grow well at all without CO2 and with low light. And, many of the stem plants listed will grow, but will be a big disappointment, with low light and no CO2 or Excel.
When this list was started, and added to, people were judging light intensity solely by watts per gallon, without even a universal agreement on what watts per gallon meant low light. We have progressed considerably since then.
