I think to grow strong wood you also need wind from time to time.

It has comparable mechanical properties to good timber. Little to no structural pine, oak or ash needed on Mars folks.

And where is the resin coming from on Mars?

"I think to grow strong wood you also need wind from time to time."I see why one might think this, but do we have a controlled experiment to back it up?

On earth, fertilizer nitrogen comes either from the air or is mainly mined from ancient birds poo. I heard people say before "There is nitrogen on Mars".. so yeah the atmosphere has about 2%, is that enough for a byproduct of a fuel plant? Argon is there as well, might be nice as a replacement for nitrogen in air as well.Soil bacteria take it out of the air and put it back. But also sometimes lighting does it thus.

I've got an aquaponics tank in my kitchen right now with a goldfish, some mini bamboo and some other decorative plants.
