I assume by HG you mean house & garden? Well i've never done a side by side, but I use canna and my buddy uses house & garden and mine end up consistently better than his, but that could just be that I'm better at this than he is. I do know a lot of people like both brands and they get great results with each. Canna costs more but you need to buy less products. There's also a lot of rumors out there about the relationship between the two brands, to which canna just sent out a newsletter this month debunking those rumors. Honestly, either brand will make for some dank ass nugs if grown with care.As title says, anyone know which yields better as base nutes, canna or HG? ive heard hg is same quality/better than canna as far as dankness of flowers, someone let me know, thanks
