Reaching heights of over 100 meters, Californian sequoias tower over Earths other 60, 000 tree species. But even these behemoths seem to have their limits: no sequoia on record has been able to grow taller than 130 meters. So what exactly is stopping these trees from growing taller, forever? Valentin Hammoudi investigates why trees have limited heights. Lesson by Valentin Hammoudi, directed by Doug Alberts

This explanation has one fatal flaw - at that height the plant is still living - understand, saps are still moving just fine, enough to maintain the life of the tissue. If the gravity was the limit, the saps will be at such slow pace they will be hardly moving and processes will not continue - tissue at the top of the tree will die - which it does not. Also, plant processes speed up and slow down with the conditions, not like in animals where there is a pump (ex. hearth) to pump at a certain rate. Please, don't criticize me if you don't understand what I am saying. I am an expert, and this explanation has merits, but needs more.

If we modiffy trees to grow thicker, grow it above Himalaya and provide enough CO2 around it, whats the highest such tree could achieve? Do all trees with same thickness have similar properties?
Video could have been better with actual trees and its name rather than a fairy tale

What would happen if we planted sequoias on a terraformed Mars? Since its 1/3 earths gravity, it would be able to transport its sap much higher right? Would trees be significantly taller?

Shoutout to the mountain ash, tallest recorded tree in history at a stunning 136m in 1870s Victoria Australia. Only measured it after they cut it down though. Typical
