Cattleya/Vanda light for the first 3.5 to 4 hours in the morning. I use no shading on the east wall of the GH. Between 10 and 11 AM the sun moves over a large oak tree which throws shading onto the GH.What light level do you grow this in?
No semi. There is approximately 50/50 mix of LECA and promix. The promix is a commercially available concoction made of milled coconut husk and perlite. The original ProMix was made with peat moss out of Canada. See pics.Rick, it looks like it’s in mostly LECA. What other media is in the pot? Are you growing it semi-hydroponically?
