THE BEGINNER'S GUIDE TO GROWROOMS
Before getting started on the road to being dealer-free, you need to determine where you can construct your growroom, how much cannabis you can realistically grow there and what kind of equipment you’ll need.

Choosing Your Space
The best growrooms begin with a well thought-out plan. Most indoor growers benefit by carefully designing their growrooms and writing their plans down on paper. Maintaining an indoor growroom allows you great influence over how well your plants perform. With the right planning, preparation and execution, you can use your chosen space to harvest your own tasty buds three, four and even five times more often than Earth’s seasonal nature allows.
Marijuana is grown in all kinds of places: perfectly built greenhouses, closets, basements or spare bedrooms. Every place has its advantages and drawbacks, but some simple guidelines should be followed when selecting a space.
1. You don’t want any light to enter or leave the room.
The brightness, and especially the color, of the lamps used can draw your neighbors’ attention. From the plants’ point of view, it’s even more important that no light gets in. The hormones that trigger the process of flowering are initiated by 12 solid hours of darkness. Only if the plants are kept in total darkness for 12 hours per day will these hormones be able to initiate flowering.

You can't assume your brothers and sisters have even considered safe surfing, and many have a lot to lose.
So I brought up the subject of a free internet anonymity program, Tor.
Go ahead and make fun of me for that. I won't mention my opinion of you. Just so everyone else at least understands that the authorities can see who they are when surfing naked.

Where'd Everybody Go?
Jan 29 2007, 1:45 am
Hey newbies! Here's the fool-proof way to go!
Deep Water Culture!
Here's a setup:
A 2x4 space inside a gorilla rack in a corner of any room. A 16 gal tub is on the floor level shelf, a hydro tank is on a shelf just above the tub. a hole is cut out for the drain tubes. A painted plywood table top with cut outs for 12 3.5" orchid baskets sits over bubble wands and covers the tank. A feed from the bottom tub constantly trickles a flow to the upper hydro "tubbler" tank. The tubbler has another pump to keep things circulating around. The overflow drains into the bottom tub to maintain exact liquid level. Add fans to suit individual room characteristics.
A 400w Metal Halide bulb and Sodium bulb with a switchable ballast is enough to yield 13-19 ozs. of Romulan with such a setup in 3-4 months from infant clones. Trust me.
Invisible Surfer!
Jan 28 2007, 9:52 pm
Please listen to me now and hear me later.
No self-respecting marijuana outlaw would blab all over a site like this without a safety feature in place!
Do you boys and girls understand that every time you make an online entry your PC is more traceable than a phone call?? When it comes to your machine's individual Internet Protocol address its about they know when you are sleeping, they know when you're awake!
When you log onto a site like this there is a permanent record of who you are through your internet service provider. Every machine is a unique individual, like a fingerprint unless you run a free anonymity program like "Tor".
torrify.com
Dowload it, install it on your machine, use it! You can become invisible too!
Safe posting is good posting!

i think you need a 400W mh light for your plants. you could transplant them in to seperate pots so then you could just move them as needed under your light. and for your cheepest way to grow... i spent about $900 on a full setup and i get some of the best smoke people have ever encountered. so search this site and you will learn all you need to grow

I have grown only one crop, so my experience is limited, but I know this, MIRACLE GROW IS CRAP, AND YOU SHOULDN'T USE IT. Try any of the great products from Botinicare or my personal favorite CNS 17. Over fertilizatoin is easy especially in the flowering stage, once you stress a plant it can take months to heal so do it right the 1at time and get some good nutrient solution

Once you want to start flowering, notice i said "once you want". The flower responde to the light it recieves, you can turn the lights cycle to 12 on 12 off to initiate flowering. In closeing these articles are not grow forums. Please read this carefully. THERE IS A QUESTION AND ANSWER SECTION WITH HUNDREDS OF ARTICLES USE THEM PLEASE. ALL YOU HAVE TO DO IS READ THE ABOVE MENTIONED SECTIONS AND YOU WILL GROW DECENT BUDS. IF YOU WANT MORE BUY A DAMN BOOK. I AM SICK OF READING THESE QUESTIONS THAT HAVE BEEN ANSWERED A THOUSAND TIMES.

Cover the walls with reflective Mylar and white and black poly plastic tarps found at most hydro supply stores. Lights cost money to run so you want to get the most bang for your buck.
Clean everything from top to bottom then repeat and then repeat. Cleanliness is so important and now is the best time to do it while the room is empty. Clean up spills immediately.
Position all your equipment (i.e. ballasts, pumps, gauges etc.) up high so in the event of a flood you won’t have a potentially DEADLY situation.
You can use any system you like for growing I find a top feed hydroponics system the easiest to maintain and one can be built for under $50.
Most hydroponics consist of a reservoir (Plastic bin from Wal-Mart or where ever), a water pump submersible, an air pump to oxygenate the water (roots need air in the water), and some tubing and irrigation drippers one for each growth site or plant. Fill the reservoir with distilled water with a PH of 5.5 - 5.9 PH up solution or PH down solution can be purchased to adjust the PH (poor mans way "use lemon juice to lower PH and baking powder to raise it) PH is measures on a scale from Acidic to Alkaline the higher the PH the more Alkaline it is and the lower is the more acidic PH pens are available. Cut holes in the lid of the tub and place 5" - 8" mesh pots in the hole "make sure you measure twice and cut once ;)" then fill the pots with sterilized and rinsed hydroton expanded clay pellets or lava rock. Place the submersible pump rated at 185 gph or more for larger systems in side the reservoir. Then run the feed line up out of the tub through a small hole in the lid and run the PVC 1/4" flex tubing from the feed line around the perimeter of the lid and add a T-splitter for each mesh pot. Place a dripper on each T-fitting and steak it into the clay pellets.

Check your breaker box in your home to make sure that you have enough amps on your outlet to run the HID lamps. HIDS especially one more than 400w will draw enough power to overload breakers and cause "FIRES" if not wired correctly. The breakers are allotted amps each will have a number on them usually 15 mine are 20 NICE ;). Also consider the other things that may share the outlets such as a fan usually 0.5 amps and an air pump if hydroponic growing usually another 0.5 amp. The key is to make sure your equipments ampere combined does not exceed that of the outlet it is all plugged into.
TIP: Some electrical appliances will not display the amps. Why I don’t know. Here is a trick to find out the ampere of a unit. Take volts over wattage. Here is a nice site to help you out. http://www.macgen.com/calcul.html has a converter. Also call your power company and find out what they are charging per kilowatt these days. This will give you an idea of how much it will cost to run your lights and everything else.
The formula is watts X hours of use X days of use then divide by 1000 and the result will be the kilowatt usage. In addition you could buy this gadget called "Kill a Watt" http://www.thinkgeek.com/gadgets/electronic/7657 that measures kilowatt usage and is programmable so you can enter your cost per kilowatt and even forecast next months bill, monitor your usage and more.

Your best bet is two build two rooms one for vegetative growth and the other for flowering. Divide the space into two sections and ensure no light will enter into your flowering room from the veg room.
Lighting
If money is not an object I recommend a 400w Metal Halide for the veg room
Also you will need at least a 400w HPS (High Pressure Sodium) Lamp. "HORTILUX" is best.
Buy both with ballasts and hoods and get the packaged deal.
If you can’t afford both lights get an HPS because you will need it for flowering but it can be used for veging also.

Your plants were Flowering --- Put the on 18 hours of Light -- turn lights on
at 9:30am --- Turn off at 2am --- They will Grow massive...
Buy some Bat Guano/Sea bird Guano - both kinds.. Save the other - blooming kind
for the big plants - you will have to flower - later on...
Now get some 3 part Genral Hydroponics Nutrients -
3 BOTTLES - 1 green - 1 pink - 1 red -- Just get Qt bottles.
Get DYNA -GRO - small bottle -
Get Eye Dropper from grow store..
Put the plants in pots with holes in bottom - 2-3 Gallon.
Buy Dirt from wall mart - $3.00 BAgs of Soil - Orange & Yellow
or Miracle Grow - with 3 month feed.
- Put soil in bottom of bucket --- pat it down - squeeze sides of CUP the plant is in
tip it sideways & pull it out -- Set it int the bucket - on Dirt - Fill in Dirt around it
then -- more -- then pat down sum more - push it in there.. yup.
Now water it & leave it under the light for 18 hours a day. Get a plastic timer in the bathroom section of wallmart,.... Red & Green pins -- then set it --
YOur lights will turn on every day automatically..
Now you are good -- Just start with 400W metal Halide - that is the best spectum
for VEGing plants -- Once the plants are bigger - We will clone them -- then make more plants for your grow room --
OK -- soo - dont overwater -- Give food 5 days out of 7 --
FEEDING :
Mix 3ml Green ------ 2ml red ---- 2ml --- pink
-----3ml Dyna gro ----
ALL IN 1 1gallon JUG with BATHTUB WATER -- PUT THAT IN WATERING CAN & WATER THE PLANTS IN ROWS -- then Get your SPRAY BOTTLE with 1ml DYNA GRO (no Gen Hydro Nutes in the spray) & WASH THE LEAFS OFF -- NICE CHUNKY SPRAY of WATER...DynA GRO CAN BE USED AS FoliaR SPRAY...
