Thanks Snype, do you mean OzzieAI? He is not referring to neem oil dunks in DWC. I think he grows in soil. Not sure it would make much difference though. I am still indecisive about what to do here. I am pretty sure I am gonna drop one of my good clones in hot water tonight. I know it kills the RA. Just not sure how much damage it does to the roots. If little or none it seems vastly superior to any other method at least for RDWC growers. I am thinking about using the bathtub as the water temp would drop far less when I plop the plants in. I would have to wait for my wife to be asleep because she would be real mad if she saw me washing root aphids into the bathtub.
Not sure why you couldnt add 100% neem to RDWC. Talk to him about it. Thats him.
Woah.....there is a lot of chit chatting going on in here.
Hey Sahdgrower....bro I hope you get this thing straightened out. I dont know your sistuation but for me...I have a good supply of clones on hand, all the time for times like yours.
The way I look at it is...its easier for me re start some new clones then it is trying to save the only ones I have. Anyway, good luck man.

I lied, I posted pictures before building the cages for the other 5 pods. I wont have time until this weekend to do it.
Anyway, these plants should get pretty large...at least that is the idea..
its kinda hard to see what happening in here because I still have some soil plants finishing out. But you can see the other 5 pods...the only pods with out the cages..
Sensi Star
White Widow X big bud
Purple Kush
And the first three
Hopefully these girls yield something decent....bud production seems to be on the slow side

In fact I think I may have a problem.
This pic if from 11/29 and bud formation looks relatively the same

So in 2 weeks nothing has happened? Your data will tell you a lot. A few days ago, you would have topped off to your marked line and recorded PPM. When you topped off today and saw the PPM, it should have gone. You need to analyze your data. All I see is picture but without many variables, pictures are useless.
I don't know snype, these plants have been fussy the whole time. Ppm drops about 10 a day. I don't top off, the r/o filter does, I only add nutrients.
Still trying to master the hydro green thumb. If I can't hit it off with my new girls in bloom then it's back to what I know best. Cheers!

Well, if your meter tells you to add then something is right. My PPM loses almost 100 every day at 800 PPM and I add back every day manualy. Each of my 10 bucket systems needs 6 gallons of top off every day. Your top off system is handicapping your data. I see bud growth daily. You are lacking data which will set you up for failure. I log almost 10 different variables daily. Data is the key.
Dang, 10 variables?? All I have to check is pH and ppm. Having such a large volume means my ppm should drop a lot slower right?

Yeah that makes sense cause you have more water but the size of the buds in rdwc should easily blow away the soil. The fact that you say that nothing has changed in nearly 2 weeks tells me there is a problem. That's why you need to be collecting more data. Here is what I collect:
Height of plant
Girth of bud
PPM before top off
PPM after top off
pH before top off
pH after top off
How much water to top off
24 hour min and max water temps
24 hour min and max air temp
24 hour min and max rH
What I added or sprayed
General notes on health
I analyze this data when things seem wrong. I maximize yields because of it. I save crops that most others would lose. I don't wait for problems before I take data. I take data every day.
Oh I suppose I measure height too along with before and after pH/ppm readings, I just need a more organized way of collecting it. Only thing I imagine it could be is my ec is to high again. I'm at 650ppm now but will go down to 450.
The thing that gets me is wen I dropped ec last time, my plants developed a cal mag problem and then I raised it a lil and bud production dropped off. Perhaps I should try the flora series.

Well I think it is safe to say my first three plants were a bust. I did a number of mistakes and quite honestly just over complicated things.
Snype...per our conversation I am now collecting and organizing data.
Every two twos I write down: pH, ppm, plant growth, and water level.
Since adding the new 4 plants to bloom two days ago they have grown 2.5" inches and consumed almost 50 ppm.
My question is...when do I replenish nutrients and bring them back up to the starting point? I set it at 550ppm and today the solution is at 513ppm.
I started working on the screens for each pod...they take a while to build. I have three done but only took a picture of one.
They are even looking perky with the lights off...
I also finally have my veg area where I want it..I plan on running 4 plants every 4 weeks. The bloom room holds 8 total so if everything works out, I should get a harvest every 4 weeks.
Here is the next batch that started veg on 12/11 with a due date in the bloom room no later then 1/11/14...350ppm/5.9pH
and here is my little make shift ebb & flow table using smart pots and lava rocks...these plants are getting a 4 week pre veg and will replace the 4 plants in the previous pic. This set should be massive after a 8 wk veg....300ppm@5.8pH

Sorry to hear that but I knew this would happen with no data and those huge buckets with not enough air. Smaller buckets and the right amount of air. Follow my formulas in my RDWC guide. RDWC is either huge yields or complete failure. No room for error. I don't lose crops. Even with water temps in the low 90s. Ive straight up mastered this shit. Its real easy when you follow rules and analyze data. One of your tasks is to see how your plant is eating via your calibrated PPM meter. As you are learning, it is best to see a good loss of PPM, 24 hours after your last top off. That reading is taken before top off. When you know what your are doing, your reading before top off will equal the same reading, 24 hours after your last top off. When you perform this method, your top off is nutes at the same strength as the system. Dont think you will accomplish this in your next run. This all comes with extreme accurate data collecting with your specific clone. It is good to grow the same clone for multiple generations to learn how to master her. You can see her health by past feed data as well with how much shes drinking. Your data will tell you what to do so the more variables you record the better. Chlorine is a must unless you are using a different proven method that isnt mine.
I came up with my methods from failing many time and almost quitting growing. It was bad. Data is your key. Without it you are flying blind.

Snype your just a beast from the Middle East. I love this hydro thing but I just don't know if I have what it takes. These next 4 plants will tell. It's just so much and whatnot. If all else fails, I have my organic soil to fall back on. I'll put in 110% though.
You have what it takes because anyone can do this. I dont know how much air you have in those huge containers. Also it is possible those containers are contanimated with something from your last crop. If you are going to use those again, scrub them well. 140 gallons of solution will require your air pumps be rated around 250 Liters/min. If you cant supply that much air, either get smaller containers or go back to soil. Imagine placing soil plants in 20 gal containers with no perlite.

Hey Snype,
Wondering what PPM of DO you shoot for and if you have done comparison/result testing for grows at varying levels of DO PPM. I realize now what you have been saying to me from the beginning regarding container size.
On a side note I got my chlorine meter (didn't realize I needed reagent for each test
) Anywho my tap chlorines at .7 ppm, I have been airing the tap out before putting in my system however this is quite tedious due to the nature of my setup (I will correct this time provided) my question is, Is there any reason not to just put the water directly into my system when I do a system change out? Sheesh I have a million questions for you but I blank when I sit in front of the computer. I will write them down next time I am in my grow room.... 15 minutes from now.
Bennyweed,
Thanks for your support, I was thinking an easy way to reduce at least a portion of the water in your system is to swap your control bucket for a 5 gallon. No need for all that space if there are no roots in it?
Have you isolated the problem in bud growth to lack of DO or do you suspect something else?

Just remembered, I added a fishtank filter to my system but I am wondering if I will just be filtering out all the chlorine I add?
If your tap has chlorine, you dont need to add any. No need to let it sit either. Just add some clorox after every 5 days after you change out your system.Hey Snype,

As far as DO, 90% saturation will be good.

90% saturation at what temp? As I understand and please correct me if I am wrong water saturates at a different level depending on temperature. So 90% saturation at 68F would be around 9ppm? I cannot measure that as I haven't the equipment but just want to be sure I am understanding.
