FUCK!!!! I thought that would be pics not links....well here is roots of p/c [img]http://[IMG]http://i1178.photobucket.com/albums/x367/larryisdumb/018.jpg[/img][/img] [img]http://[IMG]http://i1178.photobucket.com/albums/x367/larryisdumb/017.jpg[/img][/img] here's side by side with the bigger being pots [img]http://[IMG]http://i1178.photobucket.com/albums/x367/larryisdumb/016.jpg[/img][/img] [img]http://[IMG]http://i1178.photobucket.com/albums/x367/larryisdumb/015.jpg[/img][/img] covered the tub with hydroton to eliminate any light leaks(hopefully)

OK man, I'm dedicating myself to helping you get this right. So, let's get to work.

First off, to get the pics here from photo bucket you dont have to use the instert image function. Just copy the IMG code from photo bucket and paste it into your post where appropriate. The insert image function when making a post just puts the IMG codes before and after the url, and the code from photobucket already has that so you just end up with double IMG codes.

Ok, now that that's out of the way. I've done a LOT of DWC in my day and never used foggers. I remember a lot of people back in the day trying to use foggers and having issues with them, not sure why. So, first off, I would discontinue use of the foggers. Like was said earlier, the bubbles popping at the airline will maintain 100% humidity easily in that small area, so you really dont need them anyways.

Also, algea has a hard time growing in the dark. So, do everything humanly possible to block all light entering the tubs. It doesn't take much light to allow algea a foot hold, just keep that in mind when light proofing.

Why are you using perlite in the netpots if you have hydroton? Why not just use hydroton in them?

What nutes and loads are you using? Because, the girls in the pots actually don't look all that fantastic either, no offense. They look better, just not as good as I would expect.

And on a final note, can you take a picture of the water with the bubbles going? I'd like to see how much air you got going in there. I'm a strong believer in the idea that you can't have to much bubbling going on in DWC.

If you want you can hit me with a PM and me and you will get this thing on track one way or another.

Root

Thanks for the help and I'm never offended by comments on my grow. I have discontinued the fogger in the tub with the hydroton coating(haha). I didn't like the weight of hydroton and in early trials seemed to have fewer roots than perlite. Just did it from observation. I try to always have 2 of everything so I can try different things. I think I follow the pic post but I am a computer iliterate jackass so maybe not. I will pic up what you ask for.

One other thing I just noticed, I read in another thread that you are using a burner to generate CO2. Your inlet for your air pump isn't in the same room as the CO2 generator is it? Because, that would just be a bad idea. The idea is to pump as much O2 into the res as possible, and if your pump is on the floor or low to the ground it is sucking up a lot of your CO2 instead.

Best bet would be to move it outside of the tent so that it will suck fresh oxygen rich air.

bubbles and air stone

The co2 is only a week old and the pots looked better before...didn't keep up with the nute uptake. The air pump is not in the same room. Soon to be in a cold locale. Using techniflora BC line and was using B'Cuz....b' cuz they were almost free. last check was 5.7 pH @ 1000ppm

Hmm, from the looks of it you should have acceptable air in the solution. More would be better, but what you have is acceptable none the less. Yeah, you got quite a bit of algea in there bud... Definately got a light issue or something helping it along. I would imagine you will have to hit it with some h2o2 to clean it up. I personally would dump the res, clean out all that algea, and dose the solution with h202 when I filled it back up. I'm not sure of the dosages as I've never needed to use it. I'll look through some other posts and see if I can't find a recommended dose and get back with you.

The brown line is the high water mark and is the residue from the physan 20. I don't know how to get more air, my pump uses 280w. The bubble pic is the tub with pots. I appreciate your help and will try everything you suggest since my nearly 3 months of struggle have not yielded positive results. I will start with a new clean tub and old nutes and post some pics. Start from scratch under your tutelage....then if it does not work it's not my fault. I can start with new clones even in about a week or so. It is cold enough now so rez temp shouldn't be an issue as it was earlier. I have all the measuring devices I need so any numbers you want are aavailable

I checked out the pix but I didn't see any root pix. Not that I need to see them. I left a tub of chopped plants in the grow room for a week with no air and it wasn't pretty! lol

The deficiencies I see in your plants are from inadequate root delivery of nutrients.

I recommend that you acquire some food grade H2O2. Chop off all roots at the pot, just take a sharp knife and shave them off. Add 5 mls/USGal H2O2 to a tub with a fresh batch of nutes. The net pots should be put in a lid over an empty tub and flushed with a 2% solution of peroxide before setting on the fresh tub.

Peroxide should be added every three days at 4 mls/Gal throughout the grow to prevent further problems and promote growth.

If you need any formulas for calculating percentages just let me know.

I think you might be confused about your air pump power usage. I use dual outlet pumps with 2 - 12" stones per tub and the power usage is only 10 watts max for each pump. Maybe something like 2800 cc/min? The air output?

I need sleep! lol

Tomorrow.



PS: That's the same tub I use. I drill 2 small holes under the handle to feed in the air lines and 12" long stones. One in the center of each of the bottom grooves.
