Rick, thank you so much for your advice. I found the floor-dry/calcined clay/diatomaceous earth and the forest bark for orchid seedling cultivation (guess this one is okay as they are in very small pieces), but not the proper chicken grit. We only went to one feed store though, and all they had was something that looked like it had crushed oyster shells or something, and pricey. I happen to have on hand PennMix construction gravel (very small grits) that I will screen and rinse...I think it will be okay to use? I know that I also need to screen the fine particles out of the calcined clay and the forest bark.
Here are the Rinoa plants. The caudexes are bigger than what I thought they would be. The one in the left corner is the Aurum Crown.
Thanks again, Rick.
