get some xmas garland cheap, espically after xmas, take some heavy fishing line I used some 20 lb I had, cut to length garland and strand of fishing line leave enough at the bottom to tie some bell wieghts on for weight, take some line tie garland to line running the length of the garland, I bought some of the xmas light plastic holders they look like a cord holder and tie the line to it right in the center I left about 15 foot of line and wraped it up so i could drop the garland weed lol, down to different depths. Cost I paid dollar for the plastic holders and dollar apiece for the garland now this was after xmas, sure beats 50 bucks for the real weeds, and they work just fine. Do they work undecieded but if I dont deciede they are worth it im not out 50 bucks maybe 5 bucks at the most. Ill take a pic and post later.
