William van der son who owns house and garden designed the canna line before making enough money to start his own brand. I think he knows what is in Canna. I use [email protected] because it is cheap. I would never pay that much for nutrients ..what canna charges is a joke.
So what is the better nute and dont say canna because the owner of [email protected] designed the line?
Never tested side by side so i dont know.
Using your own words against you I'm simply going to say CANNA is 100x better than H&G. I think he invented H&G secondly as the cheaper knock-off for people who are budget minded, as most companies do.
