This fight will rage on and on.
Pharm drugs are made, because they have a very low tolerance for dose of medication and over sighted by the fda. While errors do happen, and get contaminated here and there, its for the best in its own ways. Consistency is key when dealing with the masses. Look at any fast food place.
There is no way to regulate a plant. Its a plant. Sun light, nutes, seed, breed and so on. This is why the fda is not pushing the issue. Because there is no way to control it. Its not a big pharma is trying to push us down. It is what it is. Deal with it.
Growing indoor with clones and light is about the close to the same you can get. However a lot of people and I am willing to go as far as most. Can not put forth the time and or money to grow them selfs. They are forced to buy it from clubs or the street. Then you are delt with the same issues as I stated above.
For more Constancy growing your own is the best bet I think, and chemicals I think are also the best idea to keep with the Constancy issue. You get the same thing over and over again.
I am a pro organic person just because I dont like the idea of chemicals and so on. I have a very weak system when it comes too chemicals.
I would like to point at one more funny issue with organics.
A lot of people I know are so pro organic, and yet the use BHO all the time.
Here you are using BHO all the time and some people I know only. Yet your using something made with Butane? Really?
Do what you do, and let it be people.
