it contains Urea as a nitrogen source, and it is no bueno with hydroponics.
So, the companies that make specific nutes for marijuana, are Advanced Nutrients, Canna, H&G, etc.
In thinking about it, i wonder how many growers actually have training in the ag/horticultural field. Seems most growers just learn from experience and reading books and sites like these, trial and error, etc..
I personally have no training just the ol hands on. So these companies probably realized hey there are all these people growing marijuana and they don't know what the fuck is up. Lets charge them 50 times what something should cost and tell it its marijuana specific. Then bam... myth becomes fact.

Lots of urea in AN products... its use in a hydro system is highly debatable, however its in many main lines, not just Miricle Grow...
Has anyone here heard of this custom GH formula that's bouncin" around?? Its called the Lucas formula or something like that. Somebody is rockin' the GH 3 part in two parts, mostly, and killin' it. I don't know the details but someone here does... I'm trying the GH 3 part with kool bloom for the first time but a friend told me about this formula to check out... Trying to see if it exists...
yeah, actually I noticed this, they seem to be the only brand to actually add urea to some of their formulas (although the % is fairly small). I really don't know if it is a performance enhancer, or a way to simply cut costs? For AN high prices, I would sincerely hope that their addition of Urea in some of their formulas is for a performance increase.
I speak with Daniel Fernandez every so often, this guy is a hydroponics/chemistry monster. He is the creator of Hydro Buddy software which basically lets you reverse engineer most formulas. Here is his article on Urea in Hydroponics
Urea in Hydroponics – Positive or Negative ?
After doing a study with several concentrations of Urea and Nitrate -both by themselves and combined – this research group found out that Urea does not improve crop yields in NFT systems and indeed pure nitrate does the best job when no media is in place. When media is introduced, organic media shows a faster Urea to Ammonia conversion but Ammonia to nitrate conversions are faster in inorganic media. However, the effect of Urea remains poor in the sense that nitrate-only crops outperformed almost all crops except for some plants grown with small quantities of Urea which proves to be beneficial in the same way as small additions of ammonia are already known to be.
So, smack me down and call me silly, but it sounds like AN is cheaping out by adding low cost Urea to some of their formulas, which is dumbfounding since they charge the highest prices.
I use Ionic Veg and Ionic Flower. A 2.5 gallon jug is about $65 They are very concentrated and last for a very long time. Also it is a simple 1 part. So no mixing, ph, boosters, bullshit, etc..
