I have done a 1-1/2 year experiment with the whole line of Advance nutrient additives (all of it) including2, 3 part, monkey juice, and with a side by side comparison with Fox Farm,Molasses, Seaweed, (Using carbon copy,same gene, light,etc.. I have had very good results with FF, but without having to add all the extra additives, I use FF in pass comparsion against Canna, Dutch Master, General Hydro, now I have move to the Humbolt nutrient line Humbolt, which is now matching AN in exact product line (so far I like the results) Before I forget, if you buy these following products from Advance Nut, Sensizym, Jump Start, part "B" Monky juice, Seaweed extract, quickly spoils in a room temp, need to be refrig other wise in the garbage they go,(stinky) trust me. I did find that I like most of the results but couldnt help being concern in using all these additives(overload) not to speak of the cost when I can get same results with FF and without all the extra effort, and as for additives, SweetLeaf, CarboLoad is another fancy form of malasses, foiler spray(in the being of the light out period,make sure you have good air curculations)) or in medium get the same results, OverDrive worked better as a foiler spray, The Tarantula and Piranha although expensive you do get alot in a little spoon full, voodoo Juice, what can I say Its expensive, I may continue using Tarantula, Piranha (maybe- now I am using Mayco Madness now by Humbolt) but wont spend the money again for Voodoo Juice. I do like Sensizym, although you probably get the same results from flat beer. VHO mainly made of "Ammoniacal Nitrogen"( Ammonia, used in kitchen floor cleaner) does straighten the stems(limbs) it seem to prolong the clones from taking root sonner(only make sense) I like to use Monkey Juice for my clones once the roots starts to show, it gentle on them plus it has almost a 4.0 ammoniacal nitrogen, Revive works, The products work fine, did it make me in wow factor? no! I feel that you can get the same results with alot less money and time involved,I have always have concern of overdosing the plants all these additives. I do see alot hype, you got to remember that there are only limited resourses that all these sourses come from, (there is alot of different car batteries labels out there, but there is only two factory in the world the make all the auto batteries) The problem is there is no regulation placed on these label (like vitamins) I could come out with a additive that state "use me and your buds will grow diamonds", who to stop me ( alittle exploded but you understand) Recerently in California EPA had some of the formula's reformatted because they said some of the ferterlizer had cancer causing carcinogenes,( only in ca, some fert, can't be sent to ca for that reseason or separately made for Ca, like "EN & EA") Keeping it simple is the best advise given, unless you enjoy it, Iam a big experiement (RD) guy, I enjoy keeping tight notes making comparisons. Have I had a big "WOW" factor NO, okay alittle, Iam not a big Dutch Master fan but when "penatrator and Light " came out, I was suprise at it reaction on the plants most leaves stood straight up. I do use penatrator on a regular bases, I do like how it works with other nutrients. I called and talked to the makers of "Suck It Up" and now waiting for its arrival, Iam curious to do a side by side comparison against penatrator (unofficial of course), makers of suck it up (extremegrowing.com) welcomes the test. You can get great results just get yourself a good base nutrient and good sourse of seaweed and molalisis and maybe a good flower booster, I really haven't seen much difference with this combination against all these high price stuff thats on the market. Iam a big fan of foiler spraying, I live in a very dry climate even in winter which allows me to spray anytime without concern for mold, foiler does the most good. Hope this help alittle.
