Alternatives to Barrels (UK Very Wet Conditions)

As even the biggest of plants take most of their nutrition from the first 18" of soil
and the vast majority of that is taken from the top 6"
It is possible to grow in very wet places by ensuring that the immediate area around the plant and down to a depth of 12" has good drainage.

I was advised that digging a barrel, with a screen attached to the bottom, 12 inches into the ground
- then filling the first 2 inches with gravel
and filling up the remaining 9 or 10 inches with a well sieved mixture of the native soil plus sand, perlite, vermiculite, compost....
Whatever combination would seem appropriate for the area and situation.

No one could afford to use actual wooden barrels.

WHAT IS AN ALTERNATIVE, TO USE FOR THE ABOVE FUCTION, TO A BARREL???
WHAT MATERIAL IS ACCEPTABLE or UNACCEPTABLE TO USE???

I`ve used swap land to grow. The best results were from plies of soil surrounded by stones. It ensures draining and the stone keeps them from eroding. I make them three ft. high and flatten the top.I also show up and trim surroundings below my grow height to prevent shadowing.

Google "swamp tubes" it will give you plenty of different ideas to avoid drowning your plants in a were area

Nice one, guys.

The marshy ground around the bottom of the valley may be suitable.

2014 is the year I try things out.
Whichever works best gets used again in 2015
If NONE of it goes well....
I try everything differently in 2015

I just NEED to be able to pass around a joint and watch people get stoned
but have no idea it's outdoor UK grown.

If you want results like that then you should look at subcools super soil recipe in the forums here. I noticed in your other thread you were planning on using native soil but the likelihood of achieving the results you want using native soil are slim. From what I know about your area, some swamp tubes filled with super soil would give you phenomenal results. I personally use super soil with some of my own tweaks and it's unbeatable

I make swamp tubes using 2 inch chicken wire fence. Simply cut to desired height and diameter then bend in a circle and secure it.. Follow that by wrapping them in some sort of canvas that will blend in with your surroundings and fill them with super soil once transported to your patch. You can place them directly into marsh areas and the main large water/tap roots will grow down into the marsh but the other fragile feeder roots will stay higher in the super soil and keep your plants from drowning
