The klx Way!

Hey klx, thx for showing us your way of growing!
Im having the problem, that the roots are turning brown and overall not looking great and some plants are dying... i made a couple of mistakes this time...

1st mistake.
the clones were too long inside the cloner, so that all the roots grew together and by seperating the roots i had to rip off some roots. and by that, there are definitely some ripped off, dead roots inbetween the healthy roots. but since im using h2o2 there shouldnt be a problem with that right? all the bad bacterias would get killed anyway...

2nd mistake
the pump was once not turned on for about 3-4 hours. i did not have any hanging leaves yet but i feel like the roots did take some damage...

3rd mistake?
How crucial do you think is it, that the stem does not come below the water level?
bcs mine go all the way down to the bottom of the tray so they get flooded aswell.

so now i try to find what causes my problem.
some roots are brown, some are almost like transparent, some look like they are crippled and some are white
and some roots above surface level and some stems start to get white mold.
did you never have mold on roots that are above the flooding surface level? i mean its always wet down there...
what would be really interesting is, what were the mistakes you made with this system?

G'day!

It is hard to know at your exact problem without knowing all the details of your grow room, environment and nutrients and additives but I can make a few guesses.

What is the % of your H2O2? You really need to be using at least 30% or more for it to be effective and controlling pathogens. What strength are you using, how frequently and how much per application?

You will definitely shock and stall your plants if you let all the roots grow together in the cloner and damage them during transplant. In that scenario I would veg them a week or so in the flood trays to give them time to get over it before flowering them.

Hard to say without a picture. It should be ok because it stays quite humid under the lid of the tray as long as it has a good fit around the edges. If your leaves were not drooping it should be ok. I experimented a lot with different flood times and frequencies, especially during the first week. From memory 30on/30off worked well or even 30on/15off

Should be ok. It is not optimum but it should be fins as long as you are religiously adding H2O2 and the floods are not too long. There should be plenty of oxygen in the nutrient as it floods.

If any of your roots are slimy then you have pathogens and your H2O2 procedure is not right. Any kind of mold is not good and again suggests to me your H2O2 regimen is not dialled in. I never had mold on my roots or stems because I used H2O2 in the correct quantities and frequencies.

What mistakes did i make? I made all the mistakes because I figured out the system and learnt as I went. This thread was written when I basically had it on cruise control and had my methods down pat.

Good luck with your system!

Im no expert but some use lactobacillus extract for outcompeting anaerobic bacteria in some situations. Using two pumps parallel can sometimes be a good idea, means your le never completely out of action if there is a failure.

Always like to hear from KLX so hope hell make an appearance, he dont come around this thread too often anymore. Hope all is well with you, Kay!

Gday Rocket, I am well mate and I hope you are too!

How goes the grow down unda? Still rocking the same leds?

Yes same old LEDs they just keep on going! But also using that big LED in the sky more and more every year.

Outdoor is hard to beat when youre in the right climate. There smelly weed, theres dank, and then theres the outdoor Sephora level. Have you ever tried high altitude? But i forget, you also have the ozonehole which doubles as the same thing for extra uv. Sorry, im a glass half-full kinda guy,

I am in the sub tropics so summer grows of any wide leaf varieties are difficult with the humidity but winter is great for flowering, just need to bring them under lights at night during veg.

I have never grown at proper high altitude, its mostly pretty flat down here with some lumps and bumps.

Melbourne and south should be equivalent to high altitude anyways, something good cone with the bad. You should be able to keep them in veg outside if you throw some light on them. Btw, where is good for seeds in OZ? My cousin is asking me since he has a nice private yard garden but hes lost when it comes to where to get it. Autos probably hest place to start for him. Any good seedbanks around?

There are a few Aussie seedbanks on Instagram but with the legal ramifications everything is still black market. For Autos his best bet would be any of the bigger seedbanks in the UK or US who are willing to ship to Oz

thx for the quick response!
Environment should be all good. canna ferts, temp: 20-26 celsius, humidity 50-60%, still in veg, ec of 1-1.1
im using 40-50ml of 12% h2o2 for the 60l rez twice a week
flooding 5m on/40m off
water is falling back down into the rez and im having a circulation pump

its just that the roots and stems that are not submerged never get in contact with the h2o2. now they get moldy...

might be a combination of all the problems i had... weak plants=sick plants


another thing...i always had the problem, that after 5-7 days the ec starts to rise.
lets say i start with a new rez of ec 1.6.
after 5 days its down to 1.4 and after 6 days it starts to climb again.
if i make a new rez with 1.6 again, it is all good again until day 5-7

All seems good. See if you can get some higher concentration H2O2 and flood for longer periods.

Your roots should be below the flood level. The bottom of the stem doesnt need to be but the roots need to get flooded so they can uptake the nutrient.

Your EC will always fluctuate a little as the plants drink more than they eat. But large fluctuations can be a sign of pathogens.

But yes starting with weak, sick plants is not a good idea. You are better off taking new clones and losing 2 weeks than trying to get sickly clones through to harvest as yield and quality will always suffer.

Good luck
