Oh yeah I can see the benefit for some people for sure.I know, I know, it's a bit expensive. But when you think about some other nutrient lineups you have to buy all sorts of additives or even their whole lineup, that adds up. I've got the full GH flora series lineup, cheaper nutes but still a lot of coin to get all of it shipped.
I'm not trying to sell anyone on it, just helping locate it for interested people, but the simplicity is unreal. Same amount through the whole grow, everything is buffered. I have 3 strains all different ages, 1 of them in dwc, when I mix nutes I don't have to mix 3 different buckets at different strengths and levels, I make one large batch and off I go. I don't need to change my res every week either because it's the same feed.
5ml/L all the way, I'm liking it. Only thing I add is a little cal-mag because I use RO water.
