Buongiorno, devo allestire un terrario in casa, e per luci, oltre ai classici led bianchi, ho anche a disposizione una striscia di 500 led blu. Servono a qualcosa o e' inutile che li metta?

parlando con Prompt mi spiegò che la lunghezza "utile" dei led blu è quella dei led chiamati Deep Blue (per i rossi invece Royal Red) tutti gli altri tipi di blu apportano un contributo minimo... di più non so!!!

A quanto ne so io (ignorante o quasi) l'ideale per le piante è raggiungere la zona dei 6700-6400 °K (o almeno così mi aveva detto un grosso vivaista di orchidee, suppongo sia simile per le carnivore visto che la fotosintesi è di un solo tipo), che equivarrebbe ad un rosino. Temo quindi che il solo blu sia un po' freddo.

ziriuz... giustissimo quello che dici per quanto riguarda la gradazione dei K... ed infatti è valida anche per le piante carnivore....
I 6000-6500 K corrispondono al bianco freddo e piu ti abbassi di K più tendi al rosso(2000-4000) mentre più sali più tendi al blu (10000)... il picco massimo di assorbimento della fotosintesi per qualsiasi pianta è un mix di rossi e blu con specifiche lunghezze d onda (per i led) le quali interferendo danno una luce tendente al violetto... per quanto riguarda i neon puoi notarlo bene con le lampade Grow Lux da (8500K)...
