Gravitropism happens, no matter what angle you put the plant. That’s kind of the point of it. Shoots grow up, roots grow down.
Unless you’re going for this? From Scientific American-- “Whatever ideas you might have on this subject [gravitropism] must also accommodate this startling fact: If you mount a plant sideways on machine that rotates it like a pig on a spit, the plant will not make a hard turn toward space. Instead, it will keep growing horizontally as if it had no ability to sense gravity at all.”
Of course, your plant is at a bare minimum of an angle, so your plant shouldn’t start growing horizontally.
What is growing at the angle supposed to add to your grow? I understand the spinning, but not why you think the plant needs help with gravitropism & why you think it will improve your grow. Not being combative, just curious.
It’s a pretty nifty creation!
