Awesome. Thank you for the detailed response.
A couple more questions (for now lol):
Would 6"-12" of standing water in the tube indicate that the bottom of the tube is equally submerged 6"-12" inches or is the tube deeper. And what are you using to stake them? How deep do the stakes go?
I saw you mentioned Osmocote, blood and bone meals. Are you using anything else? I have my organic mixes down pretty solid. I use the 3LB method for my outdoor gardening. What are your mix weights and ratios for an average tube?
Np, and yes the tube is submerged to the bottom of the swamp. So for example, if you have 3' tubes and the swamp is 1' deep; you would see water filling up a foot of your tube leaving 2 feet of air before filling with soil. But if you had a 2' deep swamp then you'd want 4' tubes to keep that water/air ratio in check. Too much water leads to suffocating plants.
I'm using tent stakes that are U shaped to stake the tubes down that are about 10" long. You can find these at sporting goods stores or Home Depot/Lowes. You can also use fence rods that catch onto the chicken wire/fencing youre using for your tubes. 2-3 will do, and drive these bitches down into the muck with a sledge hammer. This was my original plan, but with 40 tubes it'd cost too much for me to grab 3 per tube so I went with the cheaper alternative this year. Next year I'll graduate to sturdier stakes I think.
And your soil mix question is more of a personal preference in my opinion. An organic dry-land mix won't perform well in the swamps, as a swamp mix won't perform too well on land. Swamps need a lot of aeration in the soil pretty much, so don't make your mix too "heavy" when you get down and dirty next year. I don't have my soil game dialed in yet, I've been running hydro indoors for the past 8 years and have recently been opened up to the soil game. I read Teaming with Microbes and it changed my view on soil completely. Shit is gold, I'd highly recommend it!
But my mix in the swamps this year will be:
60% peat moss
30% perlite/rice hulls (rice hulls most likely bc of the silica it provides plus theyre cheaper than perlite)
10% compost
Additives: Lime, Mycorrhizae, Osmocote (14-14-14)
This mix will feed the girls til flowering, then I'll be top-dressing with guanos to provide the extra phosphorous and potassium. I'm on a short budget this year since I decided to put out more tubes than anticipated, so I'm using the KISS method to keep my pockets semi-happy haha
