hey guys, here is a guide i wrote. i wrote it a while back and have been updating it occasionally. it is oriented toward small grow boxes like pc case grows, but it still has some good info for everyone :)

GREAT GUIDES TO WEED

LIGHTS-------------
in a small grow box such as a pc case you will typically use CFL lights. they can be purchased online or at a local store. they are the normal spiral florescent bulbs. you use ~6500k bulbs for vegetative growth (from seedling to when flowering starts) and ~2700k for flowering. you want to use at least 23watt bulbs. 4 is typically the best for 23w and 26w bulbs. bulbs like 42w put out a lot of lumens but also more heat so they are typically not liked for a small box.
you want to keep the bulbs about 3 to 5 inches from the plant depending on the heat. you want to get close so that the plant can get as much of the useable as possible.
most cfl bulbs use a standard light socket base and you can find them at any hardware store. you can get the kind of female bulb sockets that plug into an outlet and line them up on a power strip or you can just run a wire across all the positives on the bases to a power cord and one across all the negatives on the bases to the power cord.
PLANTS--------
you have two choices on plants. you can use a normal plant, which is dependent on a photo-period change to enter flowering, or you can use the more popular option for small boxes which is an autoflowering plant. dwarf autoflowerings usually max out in height at a foot or 30.5 cm for those of you using metric. they can get bigger but in a small box usually wont. autoflowering means that it doesnt rely on a shortened light cycle to induce flower. instead it will automatically start to flower after a few weeks. (EDIT- there are larger autos on the market as well so make sure the one you pick a dwarf auto for a small box. Look at the advertised height. More info on this later on )
for the vegetative state, you should give your plant 18 hours of light and 6 hours of dark. and for flowering it should be 12/12. This is only for photoperiod plants though. Autoflowerings can be on 18/6 the whole grow or 20/4 or even 24/0. Basically, the light cycle isn’t that crucial for autos. I recommend 20/4 for some of the best results.
for seeds, you can buy individual seeds at the site below. they ship to the U.S. as well. the most trusted seed companies for autoflowering are: joint doctor, lowlife, short stuff, and flash seeds just to name a few off my head.

VENTILATION------
your grow box will need adequate ventilation. this is VITAL. your plants always need fresh air and your box needs to maintain certain temps. both can be done using fans. for grow boxes, 12v pc fans work best. the two most common sizes are 80mm and 120mm. if using 80mm you should have at least two fans. one for intake and one for exhaust. the exhaust always should be towards the top so it can get rid of the warm air that rises up and the intake should be toward the bottom so it can provide cool fresh air for the plants. this gives you max airflow.
to power your 12v fans you will need a 12v power supply. you should use one that looks like a laptop power supply(or any if they have appropriate ratings, the laptop style is just most common). ebay is a good place to look(about $10 shipped usually) you want to make sure it puts out more amps than your fans use. so if your fans need .5 amps (500 mah) each and you have two fans that's 1amp. if your supply puts out anything MORE than that you are good. Most supplies i've seen put out like 3 amps.
POTS/SOIL----------
for pots, you want to find a rectangle one if you can. in a grow box rectangle ones are typically the most space efficient. if you want you can just use a little plastic storage container. just punch some holes in the bottom for water drainage. you dont want to use clear containers though! your roots need darkness. if all you can find is a clear one then paint the outside black or line the inside with black plastic (ie, a thick black trash bag)
for soil, i recommend fox farm ocean forest. it is a good high nutrient soil that is great for marijuana. Although, it has too many nutrients for some strains that like less at the seedling stage (for example, the strain mi5) and they will get bad nutrient burn. i always suggest doing a 50% mix with fox farm light warrior to balance it out. most strains are fine to start in ocean forest but it doesn’t hurt to be safe.
GERMINATING YOUR SEEDS-----
ok, there are tons of ways to do this. basically a seed needs warmth and moisture to germinate. i have tried a few different ways, but in the end i always go back to my original favorite because i can have the seeds germinated between a few hours and 2 days(24hours average). i soak a paper towel in water and fold it up and place the seed in it. then i set it on a plate and put a bowl over it upside down (no paper towel should stick out). then i take the whole thing and put it in a warm place. my best results are from putting it under my blankets on my bed and turning on my heated mattress pad. my seeds usually germinate in less than a day like this... you can also put the paper towel in a bag and put it on a warm window ledge as well
after it sprouts you will see a little root coming out. at this point go to your pot with soil and dig a little hole about 1 inch down in the very center. carefully place the seed root down in the hole and gently cover it... you can put the lights on the pot 18/6 and once it pokes through the top you are on your way!!!
REFLECTIVITY---------
inside your box you want your plants to get as much of the light as they can and waste as little as possible. to do this you can add things to your walls in the box that will reflect light back to your plants. to do this you want a reflective material that reflects the max amount of light but doesnt create hot spots. the best thing you can do is add mylar to the walls. you can get it at any grow/hydro shop or online. (get at least 2 mil). if you cant get or afford mylar then just get some flat white paint and paint your walls with it in the box..... despite popular belief, foil sucks and just shouldnt be used. it literally can do more harm than good. it has low reflectivity and creates a lot of hot spots. Panda poly is another great reflective material. It is thick and white on one side and black on the other. It is sturdy stuff and is light proof.
WATERING----------------
after you put a seed in the soil, you want to keep it moist but not drenched. and once the seed is in the soil you can start an 18/6 light schedule on it.
two of the biggest mistakes new growers make is that they either over water or under water. when over watered the roots get starved of oxygen, and a seedling can develop a nitrogen deficiency (common sign is yellowing). when under watered they dont get the water they need to live. some ways to avoid these two things are: make sure you have good drainage on your pots, if you cant drain water it can also be a cause of root rot. also to check when to water stick you finger in the soil an inch or two down. you should feel the first 1-2 inches being totally dry. plants dont need to be watered every single day. depending on how dry your area is and many other factors, it can be once every other day or sometimes go 5 or 7 days without being watered. you need to let the soil dry out a little between waterings. this allows your roots to get sufficient oxygen. however, your soil should never become so dry that it gets crunchy (except the top inch or two of the soil)...in the end, listen to your plants and watch how they react. if they are drooping a bit and the soil is pretty wet, let it dry out, if the leaves droop a lot and get close to or touch the stock and actually look dry, they probably are. over watering is more common for new growers because they feel that a little extra cant hurt and keep watering just to be safe.
