Using ProMix for C. rex seedlings

[Abe1997]

Hello everyone!

Does anyone have experience growing seedlings in promix? I know HR uses this almost exclusively. I live in Redlands Florida, south west of Miami. HR has similar conditions to ours in monsoon season.

I have about 10 flasks of various rex and Triumphans eager to come out this season. Planning on experimenting with mounting a few, some in inert with charcoal, others in small grade orchiata and a few of the moyomba varieties in sphagnum.

Also just an observation from some dowiana seedlings I deflasked last fall, I grew half in typical light for seedlings I.e. bright indirect light, low direct, and the other half in direct Florida winter and spring sun. The results were insane the plants that I kept in traditional conditions used here in the state are growing steadily but are still very small. The ones left in the sun are already forming 3 plus growths and firm thick wide leaves wider than an inch. They are almost purple in color at this point.

Of course this is such a small sample size, only about 75 seedlings in each group, of a single species from a single parentage. I will not keep them out like this as summer approaches, but I took this idea from a couple of brazilian friends who grow their seedlings mounted in the brightest highest parts of their orquidario with great results. Just some food for thought!

They have since been moved to the same flats but here are a couple side by side for comparison.
