(1) How many hours per day do you illuminate your mature daylilies using these lamps? What general distance from the lamps are the daylilies?
With this light setup the lights were on 24 hours at first but I found that the daylilies started to have yellowing leaves so I gave them a 4 hour night with a 20 hour day. No more yellowing leaves.
With a previous setup, using three 2200 lumen led four foot bulbs per 12 square foot space (3 ft x 4 ft) the lights were on 24 hours and the plants did not get yellowing leaves.
The distance between the lights and the daylily leaves has varied. Most of the time the lights are just above the top of the leaves (with some leaf tips getting burned). At other times the lights are 6" to 10" from the leaves.
(2) What wavelengths do the LEDs emit? Full-spectrum, or something more specific?
One set of lights were specifically plant growth lights. They are "full spectrum", not rated for lumens but each tube produces 220 umol./m. squared/s at 8" ppfd. The other set of lights were 5000K "daylight".
(3) Have you ever tried to set seed-pods on the indoor-blooming daylilies? If so, were you successful in getting viable seeds?
Yes, I did try to set pods on some of the cultivars. They successfully set pods and matured seeds. I have not attempted to germinate any of those seeds. They seemed normal when the pods were shelled. I grow daylilies inside for reasons other than hybridizing so none of the crosses produced seeds that I am particularly interested in germinating. I'm not sure I kept the seeds (or if I did keep them, where I stored them).
(4) Is the temperature constant for your daylilies, or would it fluctuate?
The temperature for the house is set to be lower at night than during the day time. The base temperature for where the plants are is 16C at night and 19C during the day. When the lights are on the temperatures the plants experience is higher.
