-imho, enzymes are for breaking down the root matter, i think it can also keep your roots shorts if need be. however, some products are for explosive root growth then on the other hand you spending more money to eat the dead root matter or shorten roots...so its always a catch 22
i use enzymes because i flood n drain coco in my SoG Cab....and the enzymes allow me to recycle/reuse my coco. it breaks down dead root matter and has regenerative plant extracts and stimulates micro life back into the coco when reusing it.
i also use cannazym in my aero setups if i have any medium as well... i.e. coco croutons in place of hydroton.
-i found hydroguard because yea i've heard great things about it... i only bought it to give me reason to check out a hydro shop around town... (i was hella pussy showing my face, but wanted to see what they offered) so i grabbed some hydroguard because i heard all the good raving about it.
my two cents: its the bomb...especially if you have somewhat high res temps and dont wanna use h2o2. Its like an 'organic' h2o2... (analogy in reference to the way they market organics as gentle and better). The hydroguard contains all kinda beneficial bacteria to fight off shit. This is what i meant by if you let the bacteria colonize there is no way bad bacteria will take over...if they do...it must be one bad bitch.
-sm90 i've found out about this cuz i wanted to get rid of my annoying gnat problem. sm90 is just all around good. its made up of mostly oils soooo fully natural shit. its a wetting agent amongst other things. it also helps to keep my pump lines and sprayer lines clean and lubed. another thing i like about it...when i do add to the res...i can see noticeable new root growth....sm90 is a root system maintenance 'nute' and its also like an enzyme but not. its like h2o2 and hydroguard but its not. almost a mixture of all three products
soooo to answer your question....it depends on which growing method i decide, that will dictate if i use all 3 additives
and keep in mind...all this complex shit isnt needed. however in certain situation, imho...i believe its hella beneficial especially if you dont have the money to buy a res chiller for the res....sometimes you really can get by, by just adding some h2o2, some hydroguard or sm90 whatever nute/additive you like and experimenting can give you answers beyond anything i can tell ya
thas what i do...just heavy experimenting in my lab
