Anyone use Orca in their DWC grows? I know everybody and their moms use great white on there coco or soil grows but have never really seen anyone talk about orca. Anyone got any experience with it or something similar meant for DWC
 
I had a bit of trouble with slime that turned into rot with my rdwc, I tried pool shock, chlorine, pythoff, h2o2, cultured solutions. Nothing helped.

I then turned to great White and my problems were solved.

I had best results adding it to rez, I noticed a bit of growth on some surfaces but the plants were happy and that's all I really needed to see. Now I mix in water and then add to the rez because of something that's added as a carrying agent that settles to the bottom of my rez.

I stopped and ended up getting some browning of my root balls again, lack of growth. Back to the great white.

I am not using a chiller but the water temps rarely pass 20.5.

I believe my problems started with having the infection once and it persisting though all of the treatments.

You used the power in your DWC res? I wasnt sure if that would even work
 
I will never not use orca. Roots love it, never any issues with pathogens or rot. It's pricey, but worth it. As long as your water temps are below 70 (which should do the job on its own most of the time) adding Orca will give you that much more success.

I stick with the 20ml per 40gal (or whatever size you're running) and do a cap topoff mid rez change.
 
Been researching bennies when I switched from organic soil to RDWC. Most of what I read said that mycorrhizae was great for soil but not very effective in water culture and that beneficial bacteria was the way to go for hydro. I considered Orca which has a nice variety of bacteria plus four different mycorrhizae also which I wasn't sure would be of any benefit in RDWC. I then noticed Plant Revolution, maker of Orca and Great White, have a new product called King Crab which is 100% bacteria. King Crab has the same bacteria as Orca but much more concentrated. Each bacteria in Orca measures 24,960 CFU’s per ml while the bacteria count in King Crab is 25,000,000 CFU’s per ml. King Crab is a little more expensive but at a dose of only 1/2 ml / gallon water it goes a long way. So I went with King Crab and have been very pleased with my results.
Edit: Application rate for King Crab 1/2 ml/gal, 1 ml/10 gal, 5 ml/50 gal.

Right on, checking out this king crab stuff now....
 
The craziest roots ive ever had were with Orca.

Its weird I changed to pool shock and I like the clean rez but the bottom portion of my hugos roots are brown while inside the foil its all white. The root growth is decent with poolshock. Dont think its root rot cause plants are very healthy but brown roots are def not ideal.

Never happened before when I used to use Orca/GW. The root growth was insane with the bennies compared to poolshock.

So ima go back to GW this veg run and see if thats whats keeping the roots white.
