according to this research:
Red LED light (630 nm) stimulated cell growth but slightly inhibited ethanol formation. In contrast, Blue LED light (470 nm) significantly inhibited cell growth but stimulated ethanol formation.
is it good idea to put our batch under red light exposure for first 3 days and then keep it under blue light for the rest of fermentation?
if that bit of LED light can increase the production of ethanol i guess we can have our batch ready sooner, right?
what if we use red and blue light at the same time?
