Bud candy and sensizym would cause trouble for sure. Have you tried just a and b grow without any aditives?

One question about the nutes. I see sensi grow and bloom have added fulvic and humic acids. Those are organics, but from what I read are chemically stable and hard to break down. Has anyone had expirience with those? Are they safe for DWC slime-wize?

Every bucket change should be enough, but I'd be adding a bit on the third third day after the res change for a while just to be sure. BTW. don't forget you can't starve your plants forever. You'll have to give them some nutes soon. Just make sure they are pure inorganic mix.

Are those roots on first photo slimy or just stained?

If you can write a short tutorial, that would probably be most helpful.

Ok, another experiment, brewed tea at 25 C this time. Added to the res, no pH up effect after 9 hours. I've noticed foam apearing much sooner then when brewing at 22C. Perhaps higher temps cause more bacteria and less funghi in the tea.

Tripple, embryonal leaves still look full of food, so I wouldn't be feeding it yet. When they begin dying should be the right time.

Hey guys, I've figured out even better way of avoiding root slime. Don't grow anything! Seriously, I haven't heard of anyone not growing any plants and having tropble of any kind with his plants.

Are you using rockwool? If so, check if it is waterlogged. My plants almost died because rockwool soaked too much water and was drowning the roots.

I need a bit of help understanding soil and pH. I am primarely a hydro grower and have some understanding of how pH works, but soil seems a bit mor complicated to me. I don't ive in the US so I don't have any of your soil mixes available. I also don't have access to dolomite lime (no one has...

Yes. Now I just need to figure out the best way to do it :) I could add another 300m3/h intake but that will create a positive preasure and make smells very hard to controll. Then I could make that another exaust, but that would take another carbon filter and those things cost...

Thanx :) It seems we are expiriencing the same thing, so we're probably doing fine.

Matt, my tea also has some particles in it. I think it's normal but I'm quite new to tea brewing myself. By the way, I'd like to bump my question about tea and pH. Mine always bumps the pH up quite a lot. Is that normal?

Ok, I'm just saying, I spoke to more then one chemist about this and they all said that they don't see how passing electricity through silver would do anything to produce silver solution or coloid. Chemistry is in practice not as exact as they teach you in a classroom, so there might be some...

Room temps. Res temps are at 16 to 19 C (60 to 66 F), well hiden from the lights.

Nice. Now you'll have to find some nutes.

What are the ideal temps for hydro and are they different form soil techniques? My temperature sensor shows 31C (87.8F) (goes down to about 28C (82,4F) when I make a little tin foil roof above it so its not directly exposed to the light). From what I understand that is a bit high for soil, but...

Same stuff I think.

Perhaps it's the biofilm or foam created by bacterial activity. If roots are doing OK, you shouldn't worry.

I'm using advanced hydroponics nutes, but I think they market to EU primarely. As for the aquashield, I think he should be perfectly OK, even better off, with his Orca. It contains both fungi and bacteria, while aquashield contains just bacteria as far as I know.
