the guide say add some kind of product, like "Hygroguard","Subculture B"... is that any other options that can: kill bacteria, prevent root rot? Of course under the condition of well vented, well controled temp both in grow tent and in the water tank.
30% h202 1ml per gallon, or hygrozyme which is a beneficial culture that eats the bacteria and even break down dead roots.
I always start with SilicaBlast and HydroGuard (never a root problem in 6 years of use) and as posted keep water temps low. I would avoid H2O2 as it does not address long term problems just surface as well as kills good bacteria, and it only last about 24hrs. I only use H2O2 to clean buckets and equipment.
If the temp in the water tank is "well controlled" you would not have root rot and you would not need to add anything. Get a chiller.
Be sure to use clean water to start, RO or distilled. I use h2o2, kill everything in the water . I figure, if I wanted benes, I'd grow in dirt!
I just use hydrguard and rez temps are all I do. The hydrguard works well even if rez temps rise to much Sent from my Z812 using Tapatalk
yes, to kill it just go to your pet store and get some Erythromycin or Maracyn as the antibiotic will kill it as it is a bacteria. To prevent it in the same store get some pondzyme and this will protect the roots. Real simple and cheap stuff as pond people have been doing this for decades for their plants in ponds. So here is how it works. In the beginning of it all you will get what is known as Cyanobacteria which is also known as Blue Algae bacteria int eh water which is the slime you see on the roots. This is the beginning stage of it all and will led to the Pythium. This misconception of it all is that when you get root rot you actually have both Cyanobacteria and now Pythium which is a fungal problem, so you end up with a compound problem, which is why it is difficult to get rid of. Then in the end you end up with a 3rd problem which is your roots dying and therefore decomposing in the water which leads to more bacteria problems because it is dead in the water. So as you can see you have multiple issues going on biologically at the same time. Luckily there is a fix, but ti takes time to fix. You can either go with just pondzyme and let it do it job over 2 to 3 weeks and it will kill the bacteria by eating all of its food the dead material and the Cyanobacteria and Pytium will die from starving to death or you can go after the Cyanobacteria right away by inoculating it with antibiotics like we do with strep throat in 5 days and then right away after through pondzyme in to starve the Pythium and prevent it from coming back. I think I need to write this up for everyone to make it clear as to what is going on in the water so people understand it easier and everyone can have the fix.
h202.... Unless only if its BADDDDD otherwise Its called aqua shield. But you have root rot. Its not good. But its good to help. You can cut a fair amount of roots off too without effecting the plant. Please dont use hydrogen peroxide unless its FKN bad. Your temps man. Keep in check. Im accidentally as low as 14c( ducting fell) but I try to be at 20c. My two cents
3% peroxide at a ratio of 10ml per gal should be alright. "It's getting hard to be someone But it all works out It doesn't matter much to me"
