Question about CO2, dripping in coco and recirc..(for large set up)

Hello to all my true brothers and sisters. Thank you all for knowledge, experimentation, honest opinions and the heartfelt desire to achieve more while sharing, as we all know, so many of us can be so secretive.

First off, I have to say I love coco....LOVE, LOVE, LOVE COCO. I started off in coco with nothing but canna... the whole line. Never used a meter, just distilled. Everything ran perfect. Off that wifey and I bought our first house. Now, like an idiot I tried to go to rocks in a bucket system in the new house-C.G.E.- 10,000 Watts, Harvest Master Pro Plus, Gen. propane burner, 100 gal res, water chillers, air handler, 5 ton compressor, sulfur burner, the whole nine. Basically my set up can be adjusted to whatever temp including low 50's at the touch of a button. After dialing everything in kept experiencing root rot and cyanobacteria - one or the other, can't really tell. After chasing that problem since Sept.(yep, call me a dumbass) of last year and going into huge debt, I decided to go back to coco. Yeah I know :bashhead: what took me so long. Stupidity, really. Trying to chase a dream that I didn't quite understand. Rocks suck, sorry, for me they suck, now my buddy gets in upwards of 15 units in the same type of setup, however he's at a higher elevation, maybe that makes a difference maybe not. I'm not willing to try and figure it out anymore. I'm going with what I know. That brings me to this:

I have a custom built table measuring 6 ft by 14 ft, everything's in 3 gal bags, some with bcuzz coco and some with ez coco phase 1, and I'll probably pick up some canna today and see which do better. I know all coco is different but like I said prior, coco is home for me. I have drippers going to every bag with feed to waste for now until I can get comfortable with the recirc.
Now, if I have my res in one room and feed before the CO2 comes but the system recirc's, what about when the CO2 comes back on and it's feeding time? Isn't that enough time to pick up carbonic acid and bring it back to the res? Now from there where do you go? That's my only problem with the recirc. Chasing PH is not fun, you turn into a up/down slave, always checking. Hmmm, unless you have the ph nanny --something to think about.

Next question, when I read the threads on the dripping throughout the day, I've seen everything from 30 sec 3-4 times per day to 2 minutes 3-4 times a day. We all know every setup is different, however has anybody noticed an informed or confirmed difference in yield in an honest opinion? I'm interested in hearing about that. Not assumptions, but true yield difference when bagging up. Has anybody said "Wow, that's what I'm doing from now on!"?

Anyhow, thank you all for supplying all the knowledge, ideas, sarcasm and care into all your threads. It's much appreciated to us who stay in the shadows. My op. is a medical grow in cali. so I don't worry to much about anything, even after I had cops show up at the door after my apartment manager said she smelled "marijuana odor". But for all others who are trying to cultivate a natural plant in not so forgiving cities, keep it up. Screw Big B and the Rothschilds that control them. Learn to cultivate to free yourself.

I will be posting pics sometime in the next week or so of the progress of this run, but I have to finish up the room and am gonna take a couple days to get some sleep.
To give you an appetizer to marinate on -- Same system as above, all Bubba Kush...the real one (reason I say this is because I went through a lot of clones before finding one that can literally make someone's heart stop. I'm a heavy hitter and need something that I can feel, instead of think about if I'm feeling it. This also may help someone with future budgets if they have a similar strain.) Her tops are normally cut at 54 days and I let the rest fill out while I trim and dry. If I take her out all at once she's a 58 day girl. Fast and hard is how she likes it.
Sorry to post so much, just an introduction of myself.

Oh, for nutes: (this is my custom recipe)
My water is run through de-chlorinator. Found that using that helps with the trace minerals your plants can use while getting rid of the chlorine and other sediments. Another cool thing about this is if you have a larger res it fills 50 times quicker than an R/O. I have R/O as an option but it takes soooooooooooooooooo long....yeah that long. :)
H&G Aqua A & B
Cal Mag only 1.5 - 2 ml to make up if any got lost in the de-chlor
Roots Excel. (for first 3 weeks)
BCuzz Bloom
Hydroplex
Protekt
Drip Clean
Bud XL
no zym's until after roots excel, but then I'll run Multi-Enzyme, or Hydrozym
Gravity
Shooting Powder



Peace and Love
We are All ONE
remember that

I think you need a certain number of posts to be able to post pictures, but I can't wait to see them, it sounds like you've got a great setup.

I'm just finishing up my first grow so I can't offer too much insight, but I grew in 4" netpots and fine coco, watered twice a day for 1 minute, 1 hour after lights on and 3 hours before lights off, and the mix was kept at basically the same consistency the entire time.

I'm going to drop back to once a day because I think that if let to dry out just slightly it should help root growth, and I know I've seen threads that compared watering methods, and I'm pretty sure the once daily watering yielded best. Not 100% on that but I'm going to try to find the info, will link it as soon as I do.
 
Thanks bounty 29. I've been leaning towards that because I have had root rot one too many times. Not in coco but in rocks. That's a feeling that hits you in your gut. Especially when everything looks fine until week 3 of flowering.

I did post a new thread...follow me down the bubba kush trail. I'm gonna document my grow here and hope for suggestions and critique. Check it out.

Chasing PH is not fun, you turn into a up/down slave, always checking. Hmmm, unless you have the ph nanny --something to think about.

Feeding with the c02 on hasn't been a problem for me ever but I do keep my rez's in a separate room. Are your rez's in the flower room or separate room? Once you get your set up and ec lever dialed in the ph should stay pretty consistent. I go about a week without adjusting ph. Top offs are almost always plain water, fresh rez and nutes every 2 weeks and I may add nutes to one top off between rez changes. I run 120 gallons for every 3 1k lights so that is very relative as well. Running more lights/plants off a smaller rez will obviously require more maintenance.

Next question, when I read the threads on the dripping throughout the day, I've seen everything from 30 sec 3-4 times per day to 2 minutes 3-4 times a day. We all know every setup is different, however has anybody noticed an informed or confirmed difference in yield in an honest opinion? I'm interested in hearing about that. Not assumptions, but true yield difference when bagging up. Has anybody said "Wow, that's what I'm doing from now on!"?

I don't think there is any benefit to a short duration in a recirc since it's all draining back to the rez anyway. Just make sure the whole root zone gets plenty of water each time. If I run 16 plants per light (4'x4') I use 2 gallon pots and water twice a day for 15 mins. (I use the standard 15 min interval timers for water pumps). With 25 plants per light I use 1 gallon pots and water 3 times a day, 15 mins each. I use open spaghetti lines, no dripper heads, no need for them and they can clog. The only time I let my coco dry out is if I'm hand watering and I have not noticed any yeild difference.

Good luck

thanks for the input turbotanical. I really appreciate it. So no difference in yield with letting dry out and dripping a few times a day? I think I'm going to move the res into another room tomorrow and put a chiller on it since that room -nicknamed 'the sauna'- gets pretty not, a steady 88-90. But I've got to 1/4 chillers from my run in rocks so I'm good, right? If you don't think I need one (a chiller) chime in. I was just thinking with the return water sitting in there in a hot room may cause some nasties that I could possible avoid with the chiller. Looking at the room today was an incredible experience. After struggling with the rocks for the last 8 months, I saw a beautiful scene. Growth. :)

hey mister good luck with your venture into coco. it was the best decision i ever made. i highly recommend you amend your coco, not for nutes, but for aeration purposes. i use three gallon coco bags with about a one part perlite/fytocell to two parts coco and i am able to get by watering once every three days, every other day at the MOST. i can't seem to find other people that use it, but i attribute my ability to water so little on the below product.

additionally, make sure you treat your coco experience more like hydro than like soil. coco plants can handle a heavy load of nutes and experience the explosive growth of hydro, but have the added stability of a moistenable medium.
 
Thanks suckerrepellent, I will definately keep that in mind when filling up the bags. I'll have to go to the store tomorrow to pick some fytocell up. Do you recirculate your solution?
