I’m doing a experience with this autoflower, since my other ones don’t grow very tall ( between 50-70cm ) this one is growing the first stages near sunlight in order to have a tall size before growing the first true leaves. So it’s growing with the spring daylight, in the morning it gets 500lumens and then most day well above 2000lumens. In the first week it’s already bigger then my other 4week vegetative plant, I have been LST with my fingers it to keep it straight up.
Hey bro you should bury that down nice and deep. Right up to the first set of leaves. Anything below the first leaves is pretty much the root. And you won't need to support it. Good luck friend🤜🤛
