Question

What's it like for Growing Marijuana in a swamp and would I even have to water or give nutrients to the plants as the soil is very black and moist.

Answer

When growing in a swamp you have to dig down and see how deep the clay underneath is. If the soil is too moist you will drown your plants. I would recommend putting some peat moss into the ground and some dolomite lime. I would give nutrients, probably miracle grow or something like that.
