My 2010 Summer Guillera Grow Plan Overview

This is my first post on rollitup! I love this site it has tons of answers.
Anyways, I am planning on having my first grow this summer in Michigan. I still live with my parents, but that shouldn't be a problem since it's a guillera grow.
This is my rough overview plan (I am posting it so people who know more about this can help edit it)
I've researched outdoor growing a ton so I know a good amount of info.

A little ways from my house there is a forest that goes pretty deep and not many people wander back in there. There is a shallow creek running through the entire forest. I haven't found my exact location yet since we have 2 feet of snow. So here's the rough draft of my plan:

I am going to buy about 6 plastic pots that have holes in the bottom instead of soil so I can move them if needed. For a medium I'm going to buy regular gardening soil like miracle grow and fill all 6 pots. I'll put about 6-8 seeds in 5 of my pots. I'll get to the 6th pot later.
For water, I'm either going to use the cut the bottom of a 2 liter bottle and make a small hole in the cap method, and put one in each pot. Or, I would like to take advantage of the stream and set up some kind of simple irrigation system. (ideas for that would be very much appreciated. It's about 6 inches deep at most and has a small but definitely moving current)
for lighting of course I'll use the sun and I'll just have to find a spot in the woods where the sun shines the most. I'm thinking I'll put my plants inside a patch of some shrubs to hide them because there are a lot of little patches of weeds and bushes I'm this area.
The topic I lack the most knowledge about is nutrients. I will probably just get some basic nutrients in powder form and either do something like 20-10-10 for vegetative growth, then try using 10-20-20 (or similar) for flowering.
Or something like 30-15-15 for vegetative growth, then try using 15-30-30 (or similar) for flowering. (got that from another site. Recommended Types of nutes would be nice!!)
I'll just add the amount to the water. I'm not sure how long the water will last I'm guessing about a week?

So that is my very rough overview. If there are things wrong or anything please help! And please recommend soil and nutrient types, along with a system to water it so I only have to check up on them every week or so.
Any help is greatly appreciated and sorry this is so unorganized, I kept thinking of things to add and I wrote in on my iPhone
thanks again!!

Look for southern facing tree lines on the down hill side of the stream... better light and the obvious is that water is easier to get downhill... good luck man/

As far as your plan goes you have a great start. When the weather starts to get better and the snow has melted search for a good location for your plants, look for signs of people as you do not want to risk someone stumbling accross your grow. You have stated that you have a vegetative forests near your location with a moving stream, this sounds like a prime location to scour for your plot. The main reason I love bushy forest regions is because you can trim back green vegetation and plant in between bushes and shrubs to camoflauge your plants. Your going to want to prepare your planting area atleast 2 weeks prior to planting, by this I mean clean the area and make sure its pest free for a good to grow. Once you have found the ideal plot of land for your 6 plants your next issue is water, I have seen multiple irrigation systems that work wonderfully. One method of a simple irrigation system is simply to use a line that runs from the creek to your plants and pump the creek water to your plants throught the irrigation line using a water subpump ($100 or less) and a car battery as a source of electricity, this is a good watering system because you only need to pump the water about once a week depending on the temp. You can also design successful irrigation systems that use the current of the moving water to operate, I would recomend looking in to these methods although they are not my favorite simply because they are not as reliable. The 2 litre bottle trick is also very effective although simple so that is also an option. For nutrient I would recomend going organic if growing outdoors. There are multiple organic fertilizers and soil amendments that provide a good NPK ratio and are very heathy for your plant, I recomend you look into some of these fertilizers. You got a good basic start, now its just time to put the plan in motion. Hope this information is useful, if I was unclear on anything feel free to msg me. P.S. Id start the plants inside right now to establish a nice strong heathy root system and move them outside once it warms up.
