Duddha,
$2K is decent to work with, but its going to run out quick :D Your passion for nugs will soon get 10x more, when you start seeing them grow in front of your eyes, and then you when there all dried and cured and you get to pack a bowl of your OWN HOMEGROWN.. it truely dosent get better then that!!
Lighting
It all depends on how big you want to go and how many plants your going to want to grow. Also is your 12x12 all the room you have? what would be perfect would be a VEG room next to your 12x12 room soo you will have one smaller room dedicated to VEG and your big room dedicated to FLOWER. If you want to use all of your 12x12 for flower then possibly finding 4x 1000watt HPS lights would be perfect That would fill the room nicely with enough lights and space for possibly 25+ soil plants.
Veg room
-24hours a day of light
-1 or 2 T5 light arrangements
-exit and entry fan
-Solid thermometer w/humidity
-Small or medium standing fans to move air around
Flower room
-12hours of light a day
-4x1000w HPS lights and ballasts
-Entry and Exit fans with ducting hooked up to every light so they stay cool
-Solid thermostat w/humidity
-Large and medium standing fans to move around air in the room
To understand really what kind of lights and fans your going to need, you need to come up with a solid plan. Want a separate Veg/Flower room? are u going to combine them so both rooms fit in your 12x12? Are you going to start small or jump into a bigger grow? Do you want to do a
perpetual grow or one grow at a time?
Nutes
As far as nutes... If you wanted to BEST organic food for your plants that 2k would already be gone. lol nutes get super expensive! Alot of different people use alot of differnet nutes, some say this is better some say that is better, some people say
advanced nutes are great and use it 100% other say
Advanced nutes is all a sales pitch and they bullie people to use there nutes and say its great, idkk but i have heard it all. Super bloom and candy are all additives that you add to your base nutes, best bet is to go over to your local hyrdo store, ask what they got in all organic nutes and talk with the guys, maybe go talk to a bunch of hydro stores, cause chances are is one of the people you will talk to will tell you ALOT about organic nutes and will help 10fold, but asking on here i bet you will get 10 different opinions :) Me i use a simple base nute and add somethings hear and there, works great i get awesome dense, full flavor flowers all year round!
Seeds
How many you got ready to go? The "Crystal" northernlights x whitewidow if true, is a killer indica, nice a stubby plant and finishes in about 55-62 days a gravy 8 week strain
"ICE" is a interesting Whitewidow x Red skunk, its a potent hybrid, growers claim it grows like a indica and finished buds smoke and hit like a fiery sativa! finishes in about 64-70 days putting it at about a 8-9 week strain.
There is a whole bunch of stuff to be learned but your on your way to dank buds!
