Had a question. Whats a better growing medium? Long fibered sphagnum or a standart Peat moss/perlite mix?
Reason I as is, I did a bit of an experiment with D. intermedia, due to the fact of having tons of its seeds, and here it is:
I had sown seeds into dried LFS and others into CP mix.
Results (about 1-2 months later): The dried LFS is now green, the 3 D. intermedia plants are completely red and dewy. The 3 D. intermedia plants growing in peat moss are green with a hint of red, however the tenticles are red. They are also dewy.
Another observation: The plants in LFS are redder, but notisably smaller, whereas the ones in peat are about 2+ times bigger.
They are grown in exactly the same conditions (light, temp, humidity etc... they are in the same tank).
So this has led me to the thought of LSF being a better medium for good coloration, but peat is better for size. Based on this, I'm conducting the same experiment with D. binata, rotundifolia and filiformis... only problem is I think rotundifolia and filiformis seeds are not viable because I've sown them months ago with not a single plantlet...
This time however I mixed LFS and peat in one pot, and other had just peat/perlite.
So what do you think? Has anyone observed something similar to this?
