Gravity by Humboldt Nutrients and Eagle 20
Recently the United states pulled Reverse by Dutch masters because it contains carcinogens known to cause cancer aswell.
Human Health
Assessment
In carcinogenicity studies using mice, daminozide caused some
increase in the incidence of malignant and benign tumors. UDMH caused a
slight increase in liver tumors in rats, and produced liver vascular tumors
and lung tumors in mice. EPA has classified UDMH as a Group B2,
"probable human carcinogen." Since UDMH is dependent on the presence
of the parent chemical, daminozide also has been classified as a Group B2
carcinogen
information found at http://www.epa.gov/oppsrrd1/REDs/factsheets/0032fact.pdf
this page http://carcin.oxfordjournals.org/content/21/3/387.full also lists MANY other carcinogens and mutagens out there, time to start checkin ALL the bottles we use.
i know there are more but a good way to find out is to look for the "for use on ornamental plants only" warning. there are SO many carcinogens and mutagens out there.
