Helloo! Any other ideas what to do/what would you do with these ones?

●What i did to them so far:

-Cleaned from dust/dirt/ bird poop/moss/ bark and soft spots wood
-Boiled for 2 hours then left to fully dry
-Treated against pests/fungus/mold with Bochemit Opti F+(clear version) thinking i would not use them in water but more as dry decorations

The smaller ones i used as pots, but the space availbale for plants in that pots is very small so im looking for other ideas

●My concerns:

If I use them in a terrarium or a planted decoration i dont know how moss/other plants will be, considering the Bochemit solution.
Im not sure how the wood will resist if in a wet/watery place or if i'll make a kind of waterfall/stream using them, as there are many vids online(SerpaDesign, Asu, Mugen Woong, Lang diy, Terrarium Designs, Aquarium Ideas Diy, Ferret Wonderland and so on). Will they rot?

●Materials i have and i think may be helpful:

Peat soil
Akadama soil
Keto soil
Lots of different moss(and plants that grew among)
Different stones
Bark pieces
Mist maker, pump1, pump2
Aquarium almost the same dimension as this one i may cut the glass and use it as here(portrait) or in landscape
Extruded polystyrene(the one Asu use)-different thicknesses
Window net
Aquarium Silicone Sealant

●Ideas i have so far but i feel they lack something:

1. wood pic4. Setting either a backflow incense cone and maybe some air plants(and so i do not need any dish for water dripping), or a water pump, but then, what plants, where to place them, and a suitable tray or something for the water to drip and flow to the pump. Example

2.wood pic2. An incense cone and a pump, so the water will flow from the pot, and there i can place moss and these plants maybe. Example

3.wood pic8. Another incense cone/pump/mist maker, the smoke will flow through its different shapes, and if water its involved i may use a combination of soil and sealant so i will create a waterproof path for the water to flow, but what plants?and should I be concerned about water getting in touch with this wood?Maybe something like he did ?moss and mist between the shapes peaks. Example

4.And for the small wood pic?keep it as a pot?

As i said these are some ideas, i do feel like some lack something and Im very open to any suggestions/ideas/advices. I may be trying to keep the wood in a good condition as much as i could, but saw a post the other day and a comment said just do something with it and let it decay as it should, and enjoy the whole process, cause with to much treatment it will no longer be that natural. Thank you very much for reading this post so far and wish you a great day=D.
