You mean worm humus? It's about 10-15%, perlite about 15-20% and the rest is soil alone or mixed with other things like compost etc

Just make sure that young roots don't grow in this mix. You would burn your plants. So you can fill most of the pot with your mix, but top middle part should be filled with soil only.

*unless your plants are already 2+ weeks old and you are going to move them to new pots. Then it should be fine.

The seedlings get strict Pro-Mix.

I transplant around 14-16 days

Worm castings can be up to 1/3 of your soil mix actually if combined with peat moss and perlite. However it might be a little bit risky if worm castings are very rich in nutrients because you could burn your plant. That's why 15-25% is a safer value I think.

1/3 peat moss 1/3 perlite 1/3 worms castings is a very popular ratio I've heard. Never tried it though.
