Hmmm...I`m still curious. If Im correct, plants do protect themselves from too strong light by turning red, right? The sword was green-lightly brownishs for eight months (after giving MH away), now its growing strong rasberryred leaves. Protecting itsself against what now? The answer cant be kelvins.
Plants also show much more bush like growth than with T8s plus the distance between leaves (donno the right english word for this) has shorteded significantly.
I dont mean to argue, just keen on whats the difference.
