So I'm going to be growing some large strains this coming summer and I'm wondering if I should just put them straight into the garden, or like dig out some soil, put down some plastic or whatever and put in my own soil? I'm thinking I will have to feed quite a bit since they are large plants and I will be able to do this more efficiently if I create some type of large container type deal in the soil. Like a separated bed sort of thing. Then again it would be easy to put it straight into the ground, and my garden has pretty good soil. I've grown everything from corn and tomatoes to watermelon, pumpkins, and peppers in there just fine. Any advice for a first time outdoor grow?
