Here are a few shots of 8 plants in a RDWC system where the res temp is a constant 66 degrees, the cooling is from a chiller. I never get root rot and I also use H2O2, i buy it from the chemical company as I use a lot. By the way be very sure about your mixing, you can get test strips at pool...

Oxygen is an essential plant nutrient - plant root systems require oxygen for aerobic respiration, an essential plant process that releases energy for root growth and nutrient uptake. In many 'solution culture' hydroponic systems, the oxygen supplied for plant root uptake is provided mostly as...

Hydrogen Peroxide and Horticulture Hydrogen Peroxide (H2O2) is a clear sharp smelling substance very similar in appearance to water (H2O). Like water it is made up of Hydrogen and Oxygen; however H2O2 has an extra Oxygen atom in an unstable arrangement. It is this extra atom that gives H2O2...

lets look at pH first, dirt and water are very different, as your in water it is safe to set a range of 5.4 to 6.1 and don't do anything unless it moves out of that range. If your nutes are at 500 ppm and two days later there at 350ppm you need to up your ppm! It works like this, change res...

Hi guy glad to see you picked up the induction light, been looking at them for a few months now, thinking of swapping 12 x 1000w out for 12 430 or 500 induction lights. Who are they made by?

There is no doubt that indoor is better than outdoor if all thing are equal which would be hard to do. I test grow in the summer outside to pick my new strains and I found that when I clone the keepers and grow them inside they are always better than outside. IMHO

What's your Ph? Check that first if Ph OK than likely Cal or mag issue but need pix.

I know how it feels and have put down my best friends a few times. Man it tears you apart inside.

When I have problems like yours I hit them hard with H2O2, but you need to fix the cause and that can be a few things, light is getting in some where, if you using totes they are not light proof! Temp will also do this, high temps are a breeding ground. So I mix my H2O2 down to a safe handling...
