Ok, this is all assuming you live in the UK, as getting seeds is a bit of a challenge in the USA. However, here are some trusted seedbanks that I have found from searching the interwebs -

When you order these seeds, don't order huge quantities. If that gets seized at customs, your big order will be a waste of time. Instead, stagger the orders. Spend between smaller amounts over orders.
Money orders and cheques are a big no-no. Instead, use credit or debit cards. On the bill, they will only show up as an obscure company. For example, here in the UK, my company shows up as "URT1"..hardly "MASSIVE SHIPMENT OF CANNABIS SEEDS TO THIS ADDRESS".
Use a fake name when ordering, too. But don't be someone like "Stephen Hawking" or (the new) "Barack Obama" something like "Sam Jones" or get the jist?

Ok, so with the problem for the Americans out of the way, let's get cracking.

Pick a decent breeder. By this I mean Greenhouse, Dutch Passion, Lowlife, Nirvana, Joint Doctor, Sensi or Serious Seeds. By spending that little bit extra, you ensure all your seeds will pop when germinating and you will get a stable plant (like, no weird branches popping out of random places and a decent smoke).
Feminized seeds are reccomended, as you know you will get bud, no matter what (as long as they flower, lol, but with this guide, they will, right?)..Greenhouse do some pretty good feminized seed deals. I got 5 for about £15. That's fine.
/cruise control

Get a strain that finishes early-ish (so no Haze strains or Sativas), go for ones such as a "Skunk" variety, or strains developed in Holland or Canada. Be sensible. Do you really think the weather in November will be like Jamaica? I don't think so.
Some that pop to mind are -

Holland's Hope
Big Bud
The Church
Passion #1 (also good for beginners)
AK47/AK48 (stinky! be careful of neighbours)
Skunk #1
Early Pearl
Ruderalis crosses
Lowryder (but they are not covered in this guide. I will do a seperate one for them)

Your seed is as good as your growing medium. It is possible to grow top quality MJ from your garden soil - don't get me wrong. But you have no idea what the PH of that soil is (unless you test it), and the nutrient quality of it is. By buying a soil which is grom a garden centre, you will at least know how many nutrients it contains etc.

I have always stuck with Westlands with added John Innes No. 1 for seedlings. Basically, just pick a seedling soil. Not too many nutrients to burn the poor fucker, but enough to keep it going.
For when your plant begins to show signs of being potbound (which I will cover later), or nutrient deficiency, then you may consider wanting to transplant it. For my secondary soil (after about a month of being in the seedling soil and getting the occasional nutrient topup), I will put the plant into something like Westlands with added John Innes No. 3.
This contains a lot more nutrients and is for bigger, more mature plants, therefore feeding them a lot more and sustaining them. Plus, they will grow a lot faster
The most important thing is what the soil contains. This will be displayed as N-P-K. I will describe that in the next section.

WTF is N-P-K? Well some of our scientific members may know, but to all those who dont, it's the levels of Nitrogen, Phosphorous and Potassium in the soil (or plant food)
You will need 2 types of nutrients (apart from the growing medium, aka, the soil). When the plant is growing, you will need a fertilizer which is high in nitrogen as this is what the plant uses most when growing. Don't negect to get a fertilizer with trace elements and a bit of P and K as these are also used, but in lower amounts.
I reccomend Tomorite, as not only can you grow awesome tomatoes with it, but it's also pretty good for cannabis. You may also want to invest in Baby Bio. However, only add 1 OR 2 DROPS to your feeding mix (the fertilizer). This stuff can burn your plants to shit. Be DAMN careful with it. As I said, 1 or 2 drops is PLENTY.

When the plant is flowering, you will need a fertilizer that is high in phosphorous as that is what the plant uses to produce the sweet, sweet buds we all like. I use Bio Bloom which is freely available on the net, and costs around £10 for a litre. It's worth it. This is all you will need when the lights go down to 12 hours or so (end of July/August/September/October time)

Also, it has been shown that Molasses are good for plants. Basically, this is like a syrupy substance. It's not expensive, but if you want to use them, get the "Black label" version. The carbohydrates and sugars in the molasses are beneficial for the buds as they are converted into the plant's sugars, which result in stickier, sweeter buds.

Start your seedlings off in small ones. Nothing too big or adventurous as the seedling can literally "drown" in soil. Plus it will give you the chance to start them off indoors and give them the head start they need (we are gonna be good growrrs, you know).

When they get a bit too big for their homes, get bigger pots. Simple. This is when you add the bigger and better soil. Repot them, it's not difficult. Even these people can do it -

Ok, Perlite can be used to aerate your roots. Be warned, it can be expensive and isn't necessary, but it can aid if you overwater your plant - which, happens quite a bit if is your first grow.

I choose to grow in my garden. Why? I know blind spots from my neighbours (obscured by trees), my parents are cool with it and I start my plants later as they are a bit smaller, so therefore have a lower profile.
Take everything into consideration.
Smell (they will stink!), Sight (from neighbours), Sun (direct sun? Shade?), where you will put them in an emergency? (shed? garage? house?)..remember, the smell!

Let's get growing!

You turn over in your's late March/early April/May and the weatherman on the radio downstairs says that Spring has officially come.
You hear the postman drop some mail through the postbox (or not, for you Yanks) and you jump out of bed. Run down to the doormat and find an envelope for you.

A grin comes across your face, as you know all too well what is in here.
Time to crack these bitches open.

The most common method to germinate seeds is the "paper towel" method. This involves soaking some kitchen/loo roll and leaving your seeds to sit between the sheets for a good 18-24 hours. When you see the little seeds have sprouts coming out of the ends of them, then you can place them into some damp soil and keep an eye on them within the first week.
However, you must remember that when using this method, you will have to touch your seeds and this can damage them. Only use this method if you are competent that you will not damage your seedlings. If not, then the following is the better option.

Get your seeds and your pre-prepared pot (Blue Peter moment) of soil with added John Innes No. 1 (and maybe some perlite, if you decided on it), and make a little hole, about 2-3cm down. Place your seed in there, cover it over and water. SOAK THAT BITCH. but remember to keep it covered. Don't pack it too much, but enough..if you get my drift.
Repeat the watering for a few days. 4 at least.
You will soon see your baby's head emerge and you will feel like a father. Trust me.
Just remember, whatever method you use. Keep them warm. I have a light system set up underneath my bed. It suffices

This was my plant at day 6.
The cruical first few days
Now I know, it's tempting to feed your plants as much as you can to get them to become "big healthy chron plants", as Shorty in Scary Movie said. However, the trick is to only feed it when it says it needs feeding. And trust me, they won't for a while.
Keep them warm and in as much sunlight as possible. If it's a shit day, improvise. Get your desk lamp set up. Just remember not to let them stretch too much, and by this, I mean get lanky. If you want, you can keep a light source close enough to your plants so that they will not "reach for the skies" and have long internodes, resulting in good, but small buds.
Keep watering when the soil is dry. You can test by "fingering" it..put your finger a few centimetres down into the soil..if it feels dry at all, then water.
It is reccomended to let your water sit for a day before, as it gets rid of any chlorine in it. So you may wish to do this. No harm if you don't though.

My plant at day 8

My plant at day 11
So..why do you start them indoors?
Because these are only babies, remember. The big bad world out there has the odd bad day, as we do. So letting them get cold/battered or whatever in the first few days isn't nice. Remember when you were a kid? Your parents probably didn't leave you outside.
Nurture thee and treat them well, and they will reward you well

Now all you have to do is give them at least 18 hours of light per day to keep them in the vegetative stage, where they will NOT flower..aka produce bud(which isnt hard really. You could invest in a timer, but summer days are usually long, so follow the sun).

    Part 2

    Keep watering and then your plant may exhibit one of signs of a deficiency after a month or so, as the soil can feed for that long.

    That site lists all possible defiencies or problems. For example, nitrogen etc or overwatering. If your plant looks healthy, then let's get to...


    So, your plant has got too big for it's boots? It needs a new home? Well you've come to the right place, buddy.
    Grab your bigger pots and John Innes No. 3 soil..then follow this guide, as this hippy will explain it better than I ever could.

    Your plants will then (hopefully) look like this

    Transplant at night so they can recover from any shock, then after you are done, water them like there is no tomorrow. Just plain water. The plants will suck up the nutrients of the new soil in no time. You cannot overwater these plants at the moment.

    Now, if you are not growing auto-flowering plants or feminized ones, you may have to sex your plants. The plants can show sex a few weeks into growth, so I will put this in here in case yours have already, or will show's a given, of course.

    Sexing your plants..

    You want girls. Not males. None at all. So here is how you can tell if you have females.
    Thoroughly inspect your plants for any of the following (if you have bought standard, non feminized seeds)


    you want to be looking for the following..

    If you see ANY male preflowers at all..any balls..fucking rip them up (carefully) and chuck them into the compost bin far, far away from the females as pollen can fly (not your normal bin, as people may see, such as the bin men, that you have a weed plant in there..not good!)


    So your plant is getting hungry quickly? (see the last link I posted to cannabis nutrient problems)..well, get your Tomorite and measure out about 3ml to every litre of water. This is sufficient for each plant (depending on how hungry it is)..but do not overfeed. It can be difficult, but limit feeding to once a week, and maybe the odd bit of plain water between feedings to flush out any salt or other build-ups as the PH of the soil can go tits up. You want it between 5.8 and 6.8
    So now it's getting into the Autumn...
    Your plants are big and healthy, I so (well, mine were, anyway)

    The flowering season starts when the days become shorter. The sun is up for near enough 12/13 hours a day and your plant has realised the end of it's life is coming (mwuhaha) will now produce the buds you want.
    This site shows the average daylight hours per month/day..very useful
    You will now see the pre-flowers become more prominent, like so

    and will switch to the "Bloom" fertilizer.
    Follow the instructions on the packet and follow this feeding schedule;

    Week 1 of flowering (around the end of August): 1ml of Bloom, 3ml of Tomorite
    Week 2 of flowering: 2ml of Bloom, 2ml of Tomorite
    Week 3 of flowering: 3ml of Bloom, 2ml of Tomorite
    Week 4 of flowering: 3ml of Bloom, 2ml of Tomorite
    Week 5 of flowering: 4ml of Bloom, 1ml of Tomorite
    Week 6 of flowering: 5ml of Bloom
    Week 7 of flowering: 5ml of Bloom
    Week 8 of flowering: 5ml of Bloom
    For a week before you harvest, just feed with plain water to "flush" out any don't want your smoke to be tainted now do you?..

    Feed any molasses (if you use them) once a week, too. On average, a teaspoon a litre is a good measurement. It's thick, so put it in boiling water and swish it round. Then add your nutrients (above)...then water your plant with them. Molasses contain sugar which is metabolised somehow into plant-compatible sugars, making the buds stickier and sweeter on the palate.

    Your seeds should have told you how long they take to flower on the packet. On average it is about 8 weeks. Most plants finish late September-Mid October. Remember, that because you are now feeding with a "Bloom" fertilizer, the leaves WILL go a yellowish colour, as the plant uses it's nitrogen/sugars left over to go into leaf production. So don't worry if the leaves are going yellow. It's fine. It means your buds will be better and more resinous...good eh?

    Also, during any shit weather, put the plants indoors. No point coming all this way and having them killed by a strong gust of wind (we are talking Autumn here)


    When your buds are fat, firm and have brownish hairs on them, grab a magnifying glass and inspect the little crystals (or trichomes, as they are scientifically called) are a cloudy colour, then you are ready to chop. The longer you leave your plant, the more "couchlock" effect you will get..the earlier you harvest, the more "headier" your high will be.
    Your plant will be honking during this time, and for the last week, as I said..feed with nothing but water.

    So you have cut down your plants and now have sticks of godly-looking ganja?
    Well, set some time aside, as you now have to trim oThis video explains it better than I could

    Now to cure it.

    Looks good right?
    Well, leave it to dry out (at least 10 days - until it is bone dry) and then leave for another week or so in a jar..this is called the "curing" process

    Then you will have the most satisfying smoke of your life..remember, growing Cannabis is a way of life, not a joke. You can get severely fucked by the long dick of the law if you get found out.
    Loose lips sink ships. Tell nobody. Use cash whenever possible in transactions and spend a long time thinking and planning your plant plot. The slightest mistake can bring it crashing down.

    This is a very good guide and a very nice post but I feel like it belongs in BLTC considering it has to do with drugs. Maybe it's just me though.

    Good point, sir. I was divided over whether it was a bad idea, but it is 99% drugs related. If anyone wishes to move it, then feel free.

    This is about growing pot, therefore it should go to Great Outdoors, no? Perhaps one could add it to From Seed to Smoke.

    Seriously, this is one nice guide. The pictures are conveniently placed and everything. Hiding in Plain Sight is one of the best methods I have ever used.

    I do believe this guide deserves a bump. It's not a terrible necro either (Mayberry ;)). Amazing guide RemadE, I think this guide should get some more attention.

    I also think it should be moved to the BLTC section and I'm going to give it a guide prefix if you don't mind.

    What is the smell like? I have been in growhouses that have been set up right and you would not know, been in some set up by tards and they stink.

    What is it like outdoors?
  • RemadERemadE Global Moderator

    Smell became an issue around the September-early November time and of course, it's strain and weather dependent, as well as wind.

    The smell of mine wasn't too bad. On a hot, breezy day you could smell them walking past my house (great for Cops! Huge paranoia levels..and they say smoking it makes you paranoid? Lawl), but aside from that, the only smell was a sickly sweet one when you brushed up against them or were within a few feet. If anything that was the biggest aspect of paranoia for me next to them being spotted, because with smell, trees and objects can't disguise the overpowering punch to the nose that my Indicas let off.

    As for Lowryder strains, the smell isn't too bad. They also tend to grow quite quickly, too, so if there is a smell then it won't be around for too long.

    Strains to watch out for (last time I checked and asked) were:
    • Anything from the "Cheese" family such as UK Cheese or Cheese Trainwreck
    • Skunk #1. Self explanatory.
    • Lemon or just plain funky strains. The odd smell can alert people. Who the fuck has a Citrus grove in their back yard that pungent? Or a chocolatey smelling bush?

    More will be added in time. I just haven't been involved in this scene for a few years so I'm out of sync a tad. People can conceal the smell indoors with a Carbon Filter, but you never could outdoors (unless it was in a small greenhouse, but you'd need electric).

    So yeah, strain and weather are a big factor. Also harvesting them is a nightmare as they grow much bigger than most indoor ones (one of my outdoor ones was over 6ft!) and so when you cut them down, that will alert anyone within at least 50ft.

    Most growers I know use LST and other methods to keep the plants as small as possible indoors and under a SCROG or something equivalent.

    Bump and also you may want to check OP for some of the pictures and YouTube links have been removed from host.

    BTW amazing post on outdoor man.

    Tbh I have always been a indoor man every time i have grown.

    So this is a nice read.

    EDIT: just realized OP hasn't posted on this thread for ages (2011) so if op is no longer around ignore the first sentence
  • In USA seeds are getting easier to get. I prefer gummy bears, but with the awesome intelligence put into LED lights and the ability to persuade a plant to do EXACTLY what you choose, I can't say my interest isn't piqued. Fuck off Enso. You haven't grown shit. You lying little parasite.
