A buddy of mine did some swamp tube growing back in Florida. From what I recall he cleared and dug out an area & lined it with something like chicken wire making a tube going down into the ground and coming up higher than the high water line. Then you line it with heavy plastic on the sides but leave the bottom open so water can wick up into your soil but it doesn't flood when the water rises. Swamps tend to be very acidic & I recall him using large quantities of dolomite lime in his mix. Just Googled it and I see people using prefab pipes which is probably a lot easier:
And Rip, that Auto-Pulco Gold looks amazing! :clap:
