I recently purchased some of this at a hydro shop, and I'm pretty excited about it. It mixes in clean, not the sludgy mess that is the Flora Nova line, is purportedly very chelated, and doesn't leave a massive salt residue in the res to clean up every nutrient change. I'd been using a BUNCH of different one part nutrients for veg, experimenting along the way to see what did the "best", worked the cleanest, and most justified the the extra expense. To make a long story short, except for the sludgy mess associated with Flora Nova Grow, I must say it worked very well, was extremely concentrated, and dollar for dollar went the furthest out of all them. The downside of course was the mess is made in the tank, and cleaning it up with every changeout. That is why I've been searching for something else! I've tried Fox Farm's Grow Big Hydroponic veg formula, Dyna-Gro, Botanicare's Pure Blend Pro, and even Humboldt Nutrients' Oneness. <---BEWARE of that one! All of them performed almost identically, and I couldn't distinguish any noticable improvements that would justify spending anything more on the more expensive products. Dutch Master's Gold line worked well, and was very clean also, but requires the use of more than just the A and B formulas i.e Zone, Silica, and if you can afford it, ADD .27.
GH's Flora Duo line, seemingly not only has a dollar for dollar value equal to or better than many of the other products, PLUS the cleanliness, and flexibility to be used for not just the veg stage, but for transition, AND flowering. I purchased and have been using the Flora Duo line nutes almost exclusively because of that flexibility, and the bonus of an easier cleanup job, as well as value, have been exactly what I've been looking for. My plants are in transition right now, so I don't have a previous harvest to refer to yet, but I'm definitely looking for the holy grail when it comes to many of those traits I mentioned, and AS of NOW, the GH Flora Duo line is the closest thing I've found.
Unfortunately, they need to get their act together as far as their online website in concerned. It doesn't even list it on there, and doesn't tell you anything about what's in it anywhere else either. It'd be nice to know the easiest, most economical, and simplest way to avoid which of their other products NOT to buy out so as not to be doubling or even tripling up on the same substances. All the nutrient companies have their propietary secrets, and it's EXTREMELY irritating not knowing, or being allowed to be told exactly what the f*%$ you're giving your plants! Not to mention the cost, or the damaging effects doubling or tripling into the mix certain substances can do, all the while thinking you're doing the best thing for them. For instance, how many products these days, claim to have norwegian sea kelp as an additive? Or molasses? Or amino acids, organic acids, humates, or fulvates? How can it possibly be ok to give all these supplements when so many of them have one or more combinations of these ingredients in them already??? This is the shit that has me so angry!
The most straightforward company I've found excpet for Dyna Gro has been GH, but even they have stuff in their bottles they're not telling you about. Advanced Nutrients does a good job of telling you what's in their products also, almost too verbose imo, but they segment their line of products into so many different bottles, it's not even worth it. Keep it is as simple as possible, but still give them everything they need. Is that too much to ask? Apparently so, and which is why it'll continue to take many more years of very expensive trial and error.........all as prices plummet, and demand goes down. /rant over.
