Ill say this once more Roots Excelorator completely dissolves and won't clog anything, not even aero sparyers. ..and especially if you show due dilligence cleaning in between uses with h2o2. You use enzymes in conjunction at a low rate throughout nutrient changes and everything stays clean.
Say it all you want, but roots excellerator doesn't have beneficial microbes in it and that is what we are talking about here. Its good shit, I use it, but its mostly hormones that are doing the work.
Med1.. glad you corrected yourself about no place to live in hydro. I spoke with several people about this, including a guy that manages a lab that produces myco fungus for sale to various hydro nutrient makers. They do "due better" in soil but the fungus actually colonize the roots themselves, attaching themselves to the roots and actually penetrating the cellular walls of the roots. I asked him if I should add something to my hydroton for them to "live in" his words..no need. Once they are established they are established so yeah, no need to be constantly dumping them in there. As if somehow they just up and fucking disappear in a week. In my restoration work we only inoculate roots and soils ONCE with beneficials... same as with commercial ag. Its actually kind of shameful that nutrient manufacturers tell you to just keep adding and adding them.
120 ppm drop AND 5 gallons.. that got to equal what.. 200 total ppm drop in one night? Pretty greedy little fuckers you have there. I measure after topping off with plain water, my uptake record to date is 118 for 12 plants in a 50 gallon rez.
