This 2020 study investigated known and experimental effects on sprouted broccoli, white mustard, red radish, and red cabbage compounds:
“We planned development of cruciferous sprouts in hydroponics elicited with LED lighting and Methyl-Jasmonate (MeJA) to bio-stimulate production of glucosinolates, comparing effects of two types of LEDs designed for indoor food production systems.
We aimed to gain knowledge on response (germination rate, biomass yield) and phytochemical composition of fresh edible sprouts of cruciferous varieties (broccoli, radish, cabbage and mustard) under these conditions for future food production recommendations:
- Use of LED lights to grow edible cruciferous sprouts was positive in terms of biomass production and phytochemical content (glucosinolates) without any negative effects.
- Use of MeJA was positive, confirming previous results. Intensity of response for different species is useful to focus production of sprouts for specific purposes.
3-day old sprouts were placed in a growth chamber with controlled conditions (Photoperiod 18/6 h; temperature 24/18 °C; and relative humidity 60/80%), irrigated every other day to maintain enough humidity in substrate, using 1% bleach in distilled water, and collected on day 7. Trays of germinating seeds were evenly sprayed daily with 10 mL of solution for 4 days.
Total Glucosinolates (mg/100 g fresh weight) of White Mustard, Broccoli, Red Cabbage and Red Radish sprouts, under two different LED lightings, and elicited with MeJA (250 μM).
Combining MeJA spraying with different LED light treatment showed clear increases in total glucosinolate contents for all studied sprouts when sprayed for 4 days with MeJA 250 μM.”

The research group of Our model clinical trial for Changing to a youthful phenotype with broccoli sprouts keep ramping it up. They’ve published studies of MeJA effects and LED effects on sprouts separately, but not combined like this one did.
I ordered a pound of red cabbage seeds to see how I like their 3-day-old sprouts. I started soaking mustard seeds purchased from a grocery store’s spice section last year to see if they’ll sprout.
Although effects in the above graphic are compelling, I don’t want to turn my kitchen into a laboratory with LED lights and MeJA treatments. I’ll first see if red cabbage and mustard sprouts are tolerable.
