1 tbsp (15ml) per gal of 3% hydrogen peroxide... add @ least 1 time per week to recirc res... should oxidize all unwanted life...Nice setup. Im gonna be using the dutchy gold as well in my under current. I already tried a 1/4 run and had some issues with root rot or slime Im not sure where it came from I had used aqushield and hygrozyme in the mix. It was kinda wierd because I vegged em in a shallow recirculating setup with no issues with out the hygrozyme once I popped em in the big rig with the hygrozyme after 3 days they started to get icky roots. You dont have any issues with the aquashield and hygrozyme? Just curious because Im about to rerun the setup and Im xing out the shield and the zyme.
can also mix solution in spray bottle to 5:1-10:1 ratio & spray roots (slime/rot) directly...
do this w/ container plants by weekly spraying drainage holes, squeezing & spraying between container inner-wall & media, & slightly drenching top...
applicable in recirc system by maintaining min h202 concentration...
enjoy your garden!
