How to use subculture-b

I have a bad case of root rot. I poured 300 ml of h202 in my 30 gal Rez already and let it soak for 2 days. Now I'm wondering what correct dosage of subculture b should I put in my new mix of 30 gal Rez. Any help????

1 tsp per 5 gallons is maintenance dose. What method of hydro are you using? If your plants developed root rot due to low oxygen or high water temps then nothing will keep the rot away until you address those issues.

Ebb n flow. And yeh it already developed root rot. Half my cropped died already and they other half looks normal. Any suggestions?

like he said, you have to figure out what the culprit is...either lack of h2o or high temps...

Yeh it's deffinetly my high water temp.. I bought a chiller n got it down to the proper temp..

Root rot responds well once you correct res conditions. The sub-b will eat up any dead roots, and it wouldn't hurt to get some myco fungi in there either. Good luck.

Thank you my friend. Much appreciated
