I have read this before.but I wonder how many other nute co's use the same pgr's and keep it under the radar?
There are lots out there, here is the rub, they won't tell you what's in it and most don't have too because how it is labeled and the use it is for. The only way is to lab test and that's what's happening now the labs are testing for this shit.
Just some of these products are Superbud (Australia),
Phosphoload (Superbud rebranded, North America), Rock Juice (Australia), Flower Dragon (North America), Gravity (North America),
Bushmaster (North America), Boonta Bud (UK), Rox (UK),
Cyco Flower (Australia), Mega Bud (North America), Dr Nodes (renamed Mr No – North America), and Yield Masta/Sudden Impact (Australia and NZ). There are more than this I just don't have a complete list yet.
In all cases the aforementioned products contain chemical PGR actives (subclass “Growth Retardant”) such as paclobutrazol (PBZ), chlormequat chloride (CC), and/or daminozide.
These chemical actives:
Are classed as systemic pesticides
Are scheduled poisons
Have long withholding periods
Are in many cases and most countries banned for use on food/consumable crops
Are subject to strict regulations, pertaining to registration and use (crop type, application rates and times)
Are, in the case of daminozide, rated as a “probable human carcinogen” and in the case of paclobutrazol rated with, “This substance/agent has not undergone a complete evaluation and determination under US EPA's IRIS program for evidence of human carcinogenic potential”. Additionally, paclobutrazol has been shown in studies to be toxic to the liver.
I use Canna PK 13/14 as it is free of all the bad shit. There are some others so do your home work. I have heard great things about Hesi nutrients
