I play lite rock for my babies!
Cool good choice, Mythbusters did a episode on music and voice on plants, the episode is "exploding house"
THey did 4 voice rooms from soft to yelling and 4 music grow rooms with clasical all the way to rock. Pretyy sure tehy had country r&b and something else.
The rock and the yelling cds grew the plants like 6 inches taller in their experiment.
It seems the faster the beat the more growth. Their heavy metal plant was quite impressive. it wasnt pot, but for the same seeds from the same pack grown the same way with just differnt music, to see that differance was cool. It wasnt that loud either, jsut enough to hear really.
