New Spots...

Alright, so I live in florida so there is a pretty big window as to when I can grow my plants, since I am only capable of doing an outdoor grow, and I already have one crop coming in, and was just thinking of another small one, just for a sample but heres my theory:

The egyptians used to grow all kinds of plants of their own kind along the Nile river, due to the fertile soil, and the fact that they could rig up irrigation systems using the water of the river. What I'm planning on is planting several plants along a stream that I found with real fertile soil along the banks. If I did this, I would still go to check up on them perhaps every other day, but might not water them depending on how they look. It would be an all natural grow, with no nutes, ferts, or any of that. Does it sound like this idea would work?

you still need nutes preferably ORGANIC for veg and high ph and potasium for buds. and some sort of allround bug killer cause something will have a munch at your plants

Ok, well that's good to know. Because, I read this guys post, and although his was an indoor grow, I figured it would be worth a shot.

But, I should still start the plants without the nutes, until 3-4 weeks right? And when that time comes up, what kind of fertilizers should i use? I am looking for simple things that I could pick up at the local homedepot or walmart garden section, not special order things.
