Some may have different results than me in coco. Not trying to grow trees outside, just a simple sog, trying to get as much from the small space and amount of light as I can.
Having said that I followed Canna's nute schedule and used all their suggested nutes. Only variation being, I added about 10% perlite and I used RO/DI water and CalMAg instead of tap water. Simple drain to waste at about 10 -15 %.
You can look at the differences for yourself in the containers.
I think the plants liked the added air that drying out more frequently provided for them. To that end I am going to a smaller container(watered more often) next cycle. The next cycle will be in 3.75" pots even closer together.
Ok here are the plants.
A lineup of 5 the one on the right is the 2 gal pot. Much smaller cola, less density.
Hard to tell so here is a closer shot of the smaller plant(big pot).
And the other girls again.
I would guess that it weighs half of what the others do. And of course this is not exactly scientific as they were all grown from seed. But both seeds grown in large pots were smaller. As a matter of fact the roots never tried to escape the net pots using this method.
Jberry I would be interested in your experience regarding this. Root management was one of the points That Cannna really shined through on. Some of my friends using GH nutes are scratching their heads and pruning their roots.
