Which substrate won, where is the root better

First, I'll show you in detail what happened. from my experience on the 6th day after the first shoots. It was impossible to look at this sadness any longer.

Vermiculite and Diatomite

I read about the excellent root development in Vermiculite. Trust, but check! A "surprise" awaited me.

The root in Vermiculite and Diatomite is well developed, but!

• All the sprouts were in hats. It is no coincidence that the stones did not help them, as usually the viscous soil helps.
• The cotyledons are not developed in both, the green part is very weak, worse in Diatomite.
• In Vermiculite, all the roots are tiny, very tiny:

Diatomite has less branching, but the roots are slightly thicker:

I transplanted 2 sprouts into ordinary soil. Of course, the substrate remained on the roots. Below in the photo is a complete comparison.

Soil and Moss Sphagnum

These are normal tomatoes! Throughout. It only remains to compare:

In moss, the root is the most undeveloped, but the sprout is not elongated, the cotyledons are developed, however, a little twisted. The root is not developed, but plump, because the tomato found everything it needed in the moss easily and simply.

In the ground, the root is exemplary for a five-day sprout, developed, strong. The cotyledons are the best.

I will write about Arpolit separately, there are two do not understand what, barely living seedlings. I don't even want to show it.

conclusions

1. The usual Agricola soil has won! You can calm down and not look for the best substrate for germination.
2. You can see how much the plant needs nitrogen in the first days after germination! It was zero in Vermiculite and Diatomite. The semen reserves did not last long.

Have you compared soil for seed germination? How did you do it?

And I also want to ask, what do you think is it worth growing vermiculite and diatomaceous tomatoes, will there be any sense after such a childhood?

I would be grateful for your subscription and communication :)
