Hey, for additives the Nirvana dose well as a foliar. Also it has tricontanol which is a plus...
Have used the bud blood on a few different strains and found out the hard way that kush don't do well with bud blood. Others like my pineapple chunk took to it well. Not sure if it really dose add extra bud sites, or speed up flowering. Has alot of P and K,
i have tried the piranha powder, still have a load left. I cant confirm with out a lab weather it did inoculate my soil(only tried it in soil) but there are two points really, one ,the water consumption dramatically slow down, which i guess the fungi were doing there job, but it meant i couldn't water/feed as often (your ment to use it in the first two weeks of flower, i tried one in veg and one in flower)
two, any gains i did see from using piranha were probably more down to the calcium and magnesium in the powder.
i have also used the carboload powder, and am undecided if it is feeding my soil/plant, havnt tried it in hydro for fear of blocking my drip lines. It dose/did seem to help, once again with water consumption dropped off abit, but no where near as much as the piranha did.
honestly im okay with A.N., there prices are abit steep, i havnt used big bud,over drive or that,simple as you can get the same stuff for cheaper now. Just my 2pennys worth. Take it easy all.
