Saggy Leaves

Wouldnt leaving some soultion in the bins with an air stone essentially be DWC? Not that it matters just curious. Also, I was thinking that it would be a bitch to get the solution out of the bins with the plants in them come res change/final flush time.

So all that said, do you think it would be better to design the bins to drain out completely or to leave solution in there with an airstone? Either one would require a complete redesign so I am open to all options.

I like the DWC thing.....there's really no overwatering or anything. The only trick would be making sure you can empty that somehow as well; not that you'll be emptying it often but it will need to be cleaned every once in awhile.

The thing is....in my photo of my roots....the entire last two feet of them sit in water so if your ppm and ph are the same I'm wondering why your roots are rotting off on the ends. Makes me wonder about oxygenation to your root area.....if the containers are pretty airtight then I wonder if it is a matter of putting an airstone in your containers and try and get some fresh air circulating in them. Dont know if it would make a difference but is it doable? If just doesn't make sense to me that sitting in the water would rot your roots......mine sit in water all the time.....

Yeah, changing out the bins I my biggest concern. It is a bitch right now to take the lids with the plants and put them somewhere while I clean the bins. I would have to incorporate some kind of drain with a plug to make that work.

As far as the oxygen, the bins aren't even close to airtight and I don't think an airstone would stay submerged in there. I do have an airstone in the res itself and I use H2O2 every other day so oxygen shouldnt be a problem. My roots did the same thing last time where they grow to a certain point and then stop growing so I didn't think it was that big of a deal but that just shows what I know.

Actually I remember you mentioning it several times and I didn't think too much about it (or your PONTIFICATION about the plants in the corners) so that shows what I know. I was very convinced it was your nutes somehow but couldn't figure out how.

Are you using a zyme product at this point? Something that the roots are sitting seems to be burning or rotting them.....and I'm honestly not sure why.

I'd just stick an airpump line down into your containers....not necessarily in your water. I have a feeling there is less 02 flow in there than should be. It's fine that there is H202 in the solution but the roots still need to breathe even when no solution is present.....extra air pumped in would help I think but it's just a guess. (Ps...H202 level is not too strong is it?????)

I am only using 2 tbsp of H202 every other day in a 25 gal res. As far as pumping air in there, there is oneholeopen so plenty of o2 should be getting in there by itself. I was going to get a new pump and airstone tonight because my old airstone is over 50% clogged and I wanted to run more than one so I will try it and see what happens.

Well pooh.....just when I think I have it figured out. That certainly doesn't sound like too much H202 and with a big open hole sounds like plenty of 02 as well. Back to the drawing boards......:confused:

I'm dying to figure out how the corners fit in here.....

Well I just picked up two small 1" air stones for the bins and a big "bubble wand" for the main res. Hopefully that will get some more oxygen flowing in there and help my cause a little. Only 18 days to go (25 for the mother) until the 8 week mark so hopefully they all will survive.

Keep us updated....:)

Well, the small air stones are just barely submerged laying on their sides in the little dip around the bottom of the bin. They are putting out quite the blast of bubbles, but none of the bubbles seem to be going through the water. Does that matter or is oxygen being supplied to the entire area of water on a molecular level that I can't see?

I mistakenly got this bubble curtain thing that won't stick to the sides or bottom of my res. I think I am going to try to wedge it under the pump though. It is definitely putting out more bubbles than the 10" airstone ever did though.

Also, the middle plant on the left bin is starting to turn yellow, which disproves my corner theory because the right corners are ones that look good except for the nitrogen toxicity in the front one.

Well mine dissapated when you said you had a large open hole to let air in...that seems to be plenty to me....

like I say.....roots sit in alot more water than yours and I've never seen mine do that. Are you using a zyme product?
