OK, I grow poppies (papaver somniferum) indoors at 2 month interval and harvest at 4 month intervals. This supplies with me opium and all its derivatives every 2 months allowing me to harvest 6 times a year. When growing indoors:
1)Light Cycle - I use 12/12 for the first 2 months, then 18/6 for one month and then 12/12 for the final month. In theory, since poppies will produce little opium indoors, I give it a basic outdoor light cycle for 2 months. By this time, the poppies look like a lettuce with a stem coming up. Then I hit it with more light allowing the poppy to get more energy and produce more opium. For the final month (petals have fallen off, pod is growing, looks nice) i reduce it back to 12/12 so that it can 'focus' on developing more opium and seeds. By the end of the 4th month, the crown on top of the pod should be a grey/brown and be raised.
2)Growth - I grow my poppies in large soil beds in a wide closet. I lightly cover the seeds and moisten the top of the soil (using miracle grow). In about 2 days, I get seedlings. I then let the seedlings grow for a week or two and pluck the ones that have either died or are smaller thn the rest. From there I choose the best seedings and remove all the other seedlings within 5 inches vertically and 3 inches horizontally. This will let the poppies roots develop longer and wider which in turn makes a more sturdy plant with its own space. I water them with distilled water at first when the top of the soil dries (for seedlings) and when the seedlings develop their second set of shoots, I will water once every week (normally a monday) and mist the soil on thursdays (if needed....normally it is when using 18/6)
3)Harvest - I harvest the opium by doing a total alkaloid extraction rather than scoring. Doing a complete extract will give you the best yield of scoring seems hard (if you can score like a pro, then you WILL get all the opium out but chances are you wont....unless you've tried the techniques and established the proper cuts which is hard to do. Also by doing a complete alkaloid extraction, I do not have to score then early. I can harvest and extract in about 1-2 days (but its only about 45 minutes of work). I dry the extract in the sun by day and under fluorescents at night. This will give me the best yield per pod (i get about 90mg-100mg per pod this way. As with scoring, i get 70mg-80mg per pod). I grow about 20 poppies at a time which yields at least 2 grams of opium but as the opium dose goes (about the size of a match head) so about 3-5mg is a dose for beginners, i get plenty of opium for myself and others. By the time I'm done with it, I harvest the next batch and it goes on and on.
4)Conversion - I am not an opium addict nor a heroin addict. I am a morphine addict. I stop my use at heroin. I use calcium carbonate to extract the morphine (which will be a morphine base instead of hydrochloride salt). The base looks somewhat like a tanner form of crack and is smoked the same way as opium or crack or heroin (vaporization). Morphine is about 10% of the final weight of the opium so at best I get 10mg of morphine per pod. The morphine base is normally called Heroin #1 but I do not consider it like heroin so i refrain from calling it that (for both peace of mind and selling point). From that morphine base, I have the option to make morphine hydrochloride (Morphine HCL) which is suitable for intravenous injection (IV). Morphine HCL is useless/a waste in my opinion unless IV'd. I'm not one for using needles though (U-100's are watched pretty heavily now and they are not suppose to supply them to you without proof that you need it for whatever medical reason). So I also have the choice of turning that morphine base into Heroin base (Black Tar Heroin or smokable heroin known as Heroin # 2) and then convert it to actual Heroin (suitable for snorting, oral intake, IV, etc also known as Heroin # 3) and from there I can make it even more pure (Heroin # 4) which sells for a lot. But heroin production requires a watched chemical (acetic anhydride) which is a List II Watched Chemical requiring you to fill out forms and provide information (such as your address, reason for purchasing, how much was bought, etc) and buying anything over 500ml (I'm guessing here and speaking of personal experience) will land a cop at your door for inspection. Long before I started growing poppies I ordered the hardest thing first (acetic anhydride, 500ml for $25) and the next day a cop shows up and asks me about it and asked to see it and inspect the house and yard (obviously looking for other ingredients for heroin manufacture and opium production) but at the time i had nothing and got off clean. I now dont bother ordering it (but i do get the other stuff such as activated charcoal, sodium carbonate, etc) while i have someone else order the acetic anhydride. Don't be stupid.
5)Finally - Nobody's drug use is better than anyone else's. I don't care, nor does anyone else, about YOUR opinions. If someone wants to grow poppies, harvest opium, make morphine or heroin, let them. We aren't, and we shouldn't, be here to preach to the choir because all of YOUR opinions are going to go in one ear and out the other. He asked a question, we should answer, not give posts like "oh geez opium is horrible. stick to weeeeed." 99.9% of the time, the dumbasses saying such things have NEVER tried opium (and if they have, it probably wasn't real). If poppies are bad then all its derivatives must be too. So when you get beat down or hit by a car and need pain killers like hydrocodone or oxycontin, just remember where they all originated from, opium and the poppy.
That's all I'm saying. If you need any info, just let me know.
