I haven't started a huge tree farm yet, but they do seem to grow extremely fast. I also noticed you can transport trees from other planets to a different planet to beautify it.Sometimes they even grow faster then trees native to the planet...which is strange. Maybe trees from different planets should grow slower? or from different environments, in addition to slowing it down a bit. ------------------------------------------------------------------------------------------------ In addition to this idea (this is sorta off topic so you can ignore it) A way of breeding tees for specific looks and heights?
I would like to see the tree breeding to decorate my planet. They grow very fast but you do need 200-400 trees to fill your tank
It took me about 4 rounds of growing and chopping down my tree farm. And I was throwing away extra seeds too
