I started growing paphs and phrags two years ago. Most of them seem to be doing okay, but few blooms. I recently upped my lighting to Botanical LEDs, Jeff Young’s lights. Seems like it may be stimulating more growth. I have them potted in clear plastic Repotme pots, unslotted, whereas my catts and phals are in slotted pots. The unslotted ones with the paphs have apparently significant amounts of algae growing inside the pots. I recently heard (from Miss Orchid Girl) that algae can be damaging, whereas previously I’d read not to worry about algae. My question is, should I switch to slotted pots for my paphs and phrags?
