Here are some faqs you should know before trying to grow it:
1)You NEED a high elevation. Dont expect to grow anything great if you dont have that
2)The germination rate is very low on non fresh seeds. You will be extremely lucky to get a 10/14 germination rate. Normal rate if probably around 6/14
3)seeds are EXTREMELY expensive. The best deal i saw was $120 for 14 seeds
4)seeds, cuttings, plant matter, etc are illegal to own in the US
5)The process of extracting the cocaine alkaloid is rather long and boring process. You have a high risk of harming your lungs in the conversion of the paste to the hydrochloride....hell in the entire process of making the paste to having the final product you risk hurting your lungs. Your going to need a hell of a filtration system if you plan on doing it indoors. Most coca farmers (i.e the cartels) have huge plantations in jungles. You will be using things like gasoline and sulfuric acid alot so be careful.
If you are planning on growing coca and making cocaine, i suggest you check out DELETED. They are a trust worthy site that sends out to the states pretty fast. You can also buy Iboga and Khat seeds there.
Deleted the link i gave you. For shift is right. You have problems if you want to grow this and make it your without proper instruction and just because you tried it. You will go bankrupt growing coca and using it. Growing, processing, and extracting is not cheap.
Also, keep in mind:
1000 kilos of leaves = 100 kilos of coke
100 kilos of leaves = 10 kilos of coke
10 kilos of leaves = 1 kilo of coke
1 kilo of leaves = 1 pound of coke
1 pound of leaves = 1 ounce of coke
1 ounce of leaves = 10 grams of coke
10 grams of leaves = 1 gram of coke
So in order to get anything worth while you will need an ounce of leaves and that 10 grams of coke wont even cover 1/4 of the materials it takes to grow and process coke.
