Ecocomplete with some regular sand for dwarf hairgrass?

I was wondering if I could have like a 1 inch bottom layer of ecocomplete with like maybe a 1.5 or 2 inch layer of sand on top of it to grow dwarf hairgrass. I know that the sand will eventually go under, but I'm looking to have the dwarf hairgrass stay in the substrate. Will this be fine or will the sand block off circulation? Also, how deep does dwarf hair grass roots go downward? Thanks~

PS. I already have a layer of ecocomplete (20 lb) on my 20 gall long tank and its maybe 1 inch in height.

I have a tank/w Eco and DHG grew fairly well in it. I just didn't have high enough light
nor injected CO2 for it. So I pulled it out.
You might look at the Deep Blue "Solarmax T5 light fixture for that tank. It is a regular instead of the T5HO bulb. So it should be just a bit more PAR than a T8 bulb.
A T8 bulb is not enough for the DHG. In that 12" tall tank, two of them will cause you much algae problems. I have two 10g tanks(same height) and I use two T8 bulbs in
one of them, but on separate timers/w one on for only 3.5 hrs.
In the other tank I have an Odyssesa T5HO fixture raised 1.25" and only use one bulb.
This gives me just a little algae. But I do use Excel in that tank also.
You may even need to raise the Solarmax up some to keep out algae, but not much.
Almost forgot...the DHG(native/collected) is growing fairly well in this tank without injected CO2. But very slowly.

The shortest distance between any two points is a straight line...in the opposite direction...

I have a 20 long with just a finnex stingray. With 12 inches in height minus maybe the 2-3 inches of substrate, I assume that it will be well more than enough light. But that doesn't exactly answer my question about sand or the DHG /:

I don't know about the sand, it could compact and cause issues. I did the same with Flourite and sand and didn't have issues. That was only a small part of the tank but it did compact, never went anaerobic or anything. As for DHG roots, they go pretty deep, I have had some with 3+ inches. I consider it a deep rooting plant.

I had success with using just eco, and using eco mixed with petco black sand which blends pretty well with it.

I'm not into the image, but into the hobby...
