Don't repost or "redo and ask for individual plant yields." Just a tip
Moash has a point, there are serious canna specialists here. You have plenty of attention.
He is asking for more information on your setup. TO HELP.
Yield which I keep trying to type yeild (see, stupid I am)
But yield depends on too many factors. Way to many, including but not limited to, Soil, Water, Nutrients, Temperature, Atmosphere, and being able to listen to them (TAKES TIME) you could throw in 20 or 30 more factors in, Mold, Bugs, disease, and then You, you might hurt them when trying to be a good little helper. I've hurt mine. He has hurt his. That one guy over there well he destroyed his.
