Thanks for the advice.
10gal of coco man those must be monsters! Thats awesome. Yes the medium will still be wet, but your EC will be more consistent within the medium. See the drying process does bring more oxygen into the coco, but that also spikes EC and fluctuates PH in worst case scenarios. I'm eager to hear how they respond. The frequent watering will give you the increased oxygen benefits along side EC and Ph stability. Best of luck!

One of the first problems I ran into was keeping the young clones too wet, the root system did not develop. With plants going into flower, they were drying out too quick, and needed multiple times a day. I was told by DansBuds, that letting it get dry is what causes the salt buildup problems, and wildly acid PH problems.
DJM's coco tree's thread says to let the coco dry out, till surface shows just the slightest dryness for growing plants. Here is his thread -
I am not here to argue. If that works for you, great!!!
Like I said, I am just using for mothers and selecting genetics, because easier to move plants around, than hydro.
The seedlings I let dry out too much, and have major salt buildup. Feeding 600 PPM, and runoff 1300 PPM.
I am going to try letting get almost dry when young and growing, but flushing at least once a week
(florakleen and 300 PPM of feed). Then multiple feeds a day for flowering plants.
One last point. You do not want to cheap out and use solo cups. Buy the smallest airpots, think they are called .75 gallon. From pictures in article there was massive root circling.
Airpots and smartpots stop that with air pruning, causing more lateral root growth. When I throw out rootballs in 3 gallon (really like 2.2 gallon) airpots, you can not get one flake of coco to fall off, there is so much root system.
I do not have time, but it would be a great experiment to try both ways, and report results.
For me, I would like to find the weight of a saturated pot, and one ready for watering, and use that for watering/up-potting schedule.
I use about 20 to 25 percent perlite. DJM's thread says you want plants to need feeding as often as possible.
Last thought on this post. I am not being a bitch to the thread starter, but this is biggest problem on internet. Accuracy of information. You have to check 10 or more sources, to even get a 90% answer. There are tons of factors to most problems or ways of doing things. Also when many narrow down things, to accomplish goal, they think everything else was wrong, if they see a gain. There are just too many factors.
You have been having coco problems for 2 years. I just wanted to state that again. I highlighted the key points I wanted to address with you sir.
Did you figure out the exact cause of why your roots did not develop? i would wager is was not because of the presence of water as if that were so no DWC type of grow would ever succeed. They didn't develop well because they didn't get enough OXYGEN.
There are 2 ways to get oxygen with coco:
1. let it dry out which causes oxygen to take up the free space as well as cause huge fluctuations in mediums EC and PH the more it drys or
2. feed it and allow the feed to pull fresh oxygen in while maintaining a consistent EC and PH.
Notice how Dansbuds(great guy) advice happens to coincide with the above logic? I understand you are not hear to argue, but I actually don't understand what the intent of your post is.
I would be scared to give my seedlings 600ppm(1.2EC is close to what I feed during flower) and let them dry out, but if it works for you that's awesome. I never flush because I don't run into salt build up since my nutrients stay in solution instead of concentrating in the coco while it drys.
I'm not really sure how to respond to what you said about solo cups. I'm at a loss of words on that but I thought I would highlight it anyway......
Based on the last section I highlighted I get the feeling that you are trying to imply that my information is not accurate. Fair enough we are all entitled to our opinion, but I merely posted this tutorial to show people what I do since I get asked so often. If you are implying that I think letting coco dry out does not work you are wrong. It does work, but in my experience it provides more problems than success. All my coco coir issues went away when i dropped my notions of soil and accepted that it is hydroponics.
I hope your coco growing goes well!

you mention about not using solo cups but im not sure how you can ague with good results.. his methods are clearly working very well. lots of ways to skin the cat and all that.
Indeed I would also like to see what those roots look like.

The handwatering is key to watering everyday. You can feel the container and add only what is needed, I used to use a measuring cup for that.
I think the debate about whether to water everyday is wrong or not depends on the conditions of the room. It's colder and more humid vs warmer and dryer, grow room that makes the difference.
How hot the lights are and how about how cold the floor is. It all factors in. Coco rocks if you use it the right way, I believe that without any doubts at all.
Justiceman's simplistic nutrient regime is also perfect for Coco.
For me, I started using Coco when canna came out with their Cannacoco. I would only use Coco a and b along with some rhizotonic off and on as needed when transplanting and after adding bloom boosters pk12/13, I think it's called. But the PK at recommended levels, would slow down water uptake and in my belief also the plant growth. I started just using more of the a and b then only 1/4 of the PK as a one shot.
I had disco balls of og shining under the hps.
Very nice roots justiceman! I used to use grow bags and the roots would grow all along the bottom looking like that, so clean and white. Coco!!!
Well said! Thanks for the root love too. Watering practices don't fix environmental issues like a magic wand. Nothing does. If our room is too cold it needs to be heated. If it's too warm it needs to be cooled. Humidity has to be kept in check. These are things that we as a grower are responsible for and if they are not in check it doesn't matter what technique or fancy bottled nutrient we use. Nothing will ever work well unless those things are dialed in first.
