Do any of you have any experience with this type of new grow lights? They are light emmiting diode
type lights that emit a narrow spectrum in the blue range and in the red range. They use less power because they are led, and they are narrow spectrum. They do not produce the wavelengths that burn the leaves, and they don't put off lots of heat. The red lights are for the plants blooming on short days, which would include the nhils. I am wondering if we could graft nhil cuttings onto battatus rootstocks, put them back under long day light and bloom the one of a kind beauty one more year. Think about this. You grow out some precious seeds this summer. You also get some sweet potatoe rootstocks ready for this fall. You carry your grafts through the winter and
get a second crop of f1 seeds next year. This notion has many possibilities. Especially for those who can grow them inside too. The great possibility here is that you can grow a yard full of nhils, and be extremely picky about what to save and graft.
Anybody using these lights now??? Frank
