an experiment

I know that annual cornflowers are easy to grow, but as an experiment a few weeks ago I sowed half the seeds into normal MPC and half into a 50/50 mix with perite. The seeds have been in a cold greenhouse since. Today I removed some seedlings to give the others room to grow and it was very obvious that the ones grown in the perlite mix had a much better root system.

    Interesting. I've been adding vermiculite to my seed compost, but not in such a high ratio.

    It's what I've got in the gh, will look out for perlite.

    I've always thought they were pretty much interchangeable?

    What exactly does perlite do?
