Have you checked that your res is light proof? How are your temps? Plants should love that 600 watter, but that is a lot of light and heat. Sterilization should not matter as long as you wash the sterilizing agent off with a lot of water. Second thing I'd check is the rockwool. I personally...

Well, bennies themselves are organic obviously, but other then that, no, they shouldn't. Some of the ingredients in a tea are organic (molases), but those should be spent by the developing bacteria in the brewing process.

WelshMagic, frst of all, you mention H2O2. You know it is not to be used together with benneficials? Second, you say "pretty much all the other bull that goes with hydro". I think your problem is that you are pouring tons of crap in your bucket that is feeding slime. Instead of finding new...

I don't think there should be a special right to grow plants. What I do believe is that we are born free, and no one has the right to limit our freedom unless he can objectively prove that with our behaviour we are hurting other living beings. This is a fundamental principle upon every free...

Nope, very different strains. I was planing on separating them once they got a bit bigger, but it turned out one plant was sensitive even to lower then recomended nute concentrations I fed my plants. Whats suprising is that it is the plant that by comon knowlidge is a more heavy feeding strain.

Are you seing a doctor for your health issues. If you are, and are using your prescibed meds without achieving a full recovery, that would be a good starting point.

She is at 500 uS and is showing healthy new growth already.

Yes, there is a lot of information online, but most are tied to pseudoscientific alternative medicine claims I really don't count as reliable. As I said, even if an electrical current does pass through the electrodes, you would get hydrohen and oxygen, not silver ions as water molecule takes...

Are sure you can ever clean every piece of your grow room and equipment of every last spore? I mean, look at operating rooms in hospitals. Every instrument is heat sterilized. Every surface is made flat so it can be easily cleaned with strong cleaning agents, everyone comes in with clean clothes...

As many have noticed, it's impossible to keep a sterile res. No mater how well you clean and what you add, there will be bacteria and other microbes in there. Adding some H2O2 or chlorine can make it harder for the microbes to grow, but the amount that would be needed for an enviroment where...

Yep, looks like too much nitrogen.

Heisenberg (or anyone using tea successfully), my last brew of tea caused pH to go from 6 to 6,7 in a day and made quite a lot of foam in my res, while the last one had no such drastic effects. Is that normal, or does it indicate too much sugar left in my brew? Bigest difference I can think...

Thanx :) I'm changing my res every 7 days so that shouldn't be a problem. I have put my plants in separate buckets yesterday and given the "sick" one a bit less nutes. Now it has only 600 uS while the other one gets 800 again. I hope I'll be seing positive changes by tomorrow...

There will be large scale operations that will sell reasonable quality weed for reasonable price, then there will be small tightly controlled outdoor and indoor (greenhouse) operations that will sell premium quality for much higher price, and as always, there will be hobyists growing their own...

Hello from the almost as small neighbouring country :smile:

Erm... I have spoken to some chemists not long ago just about this silver hype and they were for starters all very skeptical about this method of introducing silvet to water solution. First of all, zero EC water means it is an insulator (no electrons pass through it, no electric circuit is...

I have noticed roots loke to act as a filter, catching particles that float in a bubbling water. Powdery coating might even just be soil particles from EWC. I get those on my roots.

Roots get damaged and your plants start looking sad.

So, I have 2 plants in a DWC bucket. One is doing fine, other has, I have recently noticed, sterted having new leaves curl downward at the edges (I think it's called the claw). They are dark green color with area where they curve tinted almost purplish. They are almost 4 weeks old, under...

Binds minerals? I have no idea how that will react with your nutes. Order pond zyme or some other product confirmed to go well with DWC. Also check the topic about brewing microbal tea. Some had problems with it, some love it. Might be worth a try.
