I moved a half dozen of those Princess Pink seedlings out onto the patio, stationed under a wicker bench. They replaced some Adenium seedlings that are now in 1 gal. pots and in full sun until about 2 PM, when the sun comes through two panels of the solarium glass. Those Plumeria seedlings will get a smidgen of sun, but always filtered by the wicker. Mainly they'll just get fresh air, bright light, and rain. They are growing some and so far are looking good.
