LED grow light planting experiment, comparison of 5 light recipes, planting basil and lettuce — 5 spectra LED grow Lights making

Basil and lettuce grown now; Planting trials of 5 spectra are about to begin

The spectra of 2 experiments have been mentioned in the previous article.

1, Basil Hydroponic Planting Spectrum:


2, Indoor cultivated lettuce spectrum:

Among the spectra we selected for the experiment, two of them are very close to the spectra of the two papers, namely F190 and F93 spectra; among them, the F93 spectrum has two independent channels, a single UVA spectrum channel, and the other three are F22 and F95 spectrum, as well as the solar spectrum, we will use these 5 spectra to grow basil and lettuce, and the PPFD will be uniformly adjusted to about 300µmol/m²/s. After harvesting, you can see whether there are differences in the spectra.

The following are several spectrograms and corresponding sample LED plant lights:

Experimental light recipe 1: F190 spectrum, which we will use to grow basil and lettuce

F190 spectrum, blue light wavelength 435nm red light wavelength 663nm
Experimental light recipe 2: F22 spectrum, Also grow basil and lettuce
F22 spectrum, blue 450nm red 660nm
Experimental light recipe 3: F93 spectrum, dual channel, channel 2, UVA, PPFD can be adjusted
F93 spectrum, a separate UVA channel, will be lit on the 10th day of field planting
Experimental light recipe 4: F95 spectrum, dual channel, channel 2 contains UVA and far red light
F95 spectrum, channel 2 will be turned on 10 days after planting, PPFD: about 10µmol/m²/s

Experimental light recipe 5: SUL spectrum, solar spectrum, this is a spectrum added than originally planned

SUL spectrum, Solar spectrum

Let us look forward to the test results!

If you have a plant light spectrum that needs to be tested, you can leave a message. If necessary, I will design and make a plant light close to it for you to use as a test.

Put a picture of the current lettuce and basil planting as the cover
