I use piranha, tarantula and voodoo juice in hydro.....ebb & flow. The piranha and tarantula leave some residue but they WORK. You can reduce this residue by making a "tea bag" to hold the microbes (taranula/piranha) that will keep your res more clean.
If you use voodoo juice, you need to also use carbo load...it give the microbes food and will GREATLY increase their productivity. I suggest carbo load regardless, as it will enhance your bud production, particularly enhancing resin and swelling.
I also recommend big bud and overdrive during flowering. They absolutely rock. Really pack on the weight and crystals.
Do not use H2O2 with microbes and enzymes, as it will kill the pathogens. Basically H2O2 creates a sterile root zone, and the enzyme/microbe creates a beneficial bacterial and fungal root zone. Both are excellent (though I prefer the microbal activity....bigger root mass) ways to enhance your roots, and therefore your plants overall size and health.
Personally....I run AN 3 part (micro, grow, bloom) with humic acid, fulvic acid, barricade (potassium silica), super tea grow & bloom, carbo load, sweet leaf, sensizyme, tarantula, piranha, voodoo juice, bud blood, big bud, and overdrive. I started with just 3 part and big bud, and I see a greater yield each time I include an additive. Right now I am using their full line less scorpion juice. Pricey, but wth.
Any time you need anything, pm or write. I read ALOT about AN and have used alot of their products.
Oh yeah.....and when you add AN nutes....do it in this order:
SensiZym
B-52
Silica
Fulvic acid
Humic acid
Piranha
Tarantula
Voodoo
Good luck and happy growing!
