I found this on amazon https://www.amazon.com/Living-Tropical-Greenhouse-Creating-Butterflies/dp/1861081235/ref=pd_rhf_gw_p_img_8?ie=UTF8&psc=1&refRID=PWAF4FQTA1QM8RHSTQEF  .

Anyone read it? Its abit old. I dont want outdated technices, but maybe they arent?

Any more books you guys can recommend?
