Some questions about the DWC system

[Mr. Ganja]

I've seen many of you fellas using the DWC systems and I think it's nice and plan on using it in the near future when I have have my own growroom.
Anyways, I was wondering. How does the system work for really small plants? And by that I mean seedlings that have just been germinated in rockwool and are ready to be transfered.
Wouldn't a week old plant have very little root clusters? How would the water being splashed by the airstones be able to penetrate though the 4-6 inch worth of claypebbles and reach the small root clusters?
Does the water level have to be set so high, even to the point where it submerges most of the hydrotron? Then will it be able to splash the roots of the young plant?
I know this is a stupid newbie question, but I'm a bit buzzed right now and I was itching to ask.

I wonder the same thing, believe it or not.

Someone please correct me if I'm wrong as this is really just my theory. I believe that you could submerge the net pot just a little to allow the wicking action of the medium to feed the roots. I know this works with perlite but I've never used Hydroton before. The splashing from the bubbles may also be sufficient but then again I'm not sure. You could possibly even thread a wick throughout the pot which in turn is submerged in the nutrient solution.
These are just some of the ideas I've come up with before attempting DWC myself. They may not be plausible.

all you have to do is get the netpot right above the water, bubbles bubbling and believe it or not, all the hydroton gets wet by transference and the roots will seek out the wetness...Do not put netpot in water because everything will stay too wet...all you need is damp. HTH, lw

Well, I don't necessarily agree with that statement...I have had some seedlings in perlite with the roots completely submerged under water: the plants seem to do fine as long as the roots get enough oxygen without much contact with light. The way I look at it, a mature plant is going to have its roots dangling in the water, and as long as there are no signs of overwatering, you are doing fine. I feel it is completely easy to start in perlite if you have never attempted a hydroponic grow before. You can grow in a quart sized paint bucket, just drill some holes in it (it may be ghetto, but it is the same basic principle as a netpot). Once the seedlings mature to the point where they need nutrients, throw them into your dwc system and watch em grow.

[latewood]

sure you can, but...
My root system will kick your root system's ass, because my root system had to work to get fed as opposed to just laying in solution...this is 'old school' DWC knowledge, sorry

basic dwc principle...establish a strong root system by encouraging roots to seek out the readily available nutrients...OH yes, you are right about this...Oxygenated nutrients.

It is different once plant is mature and wants to uptake nutrients at a faster rate...:thumbsup:

matter of fact: I have clones rooting in dwc as we speak...and I had to take a gallon of water out of rez because the netpots were too wet. not enough oxygen to the small interior root system! Now I have white fuzzy's :dance: starting to pokeout all over.

I agree about rooting in perlite...If you followed my grows, you would see that I am almost finished with the 2nd generation of clones in a system I built...using perlite as a medium, all they way.

and ghetto, Hell ask anybody around here...I have built and grown hydro in just about everything you can Imagine.

I made a great set of bubblers out of empty distilled water jugs and grew lbs. out of them over 2-3 grows, until I evolved beyond them...I use them for vegging, sometimes.

Well, I've got to go dig a spliff out of my gooey buds and contemplate your doubting my word on this?:smokin:
Perhaps you should research this a bit...I am sure you will be able to find confirmation of my theory.

In the words of the immortal "Donnie Baker"..."I gotta go"

Hey,
Let me preface my comments with a few quick words... I commend you on your knowledge.
I wasn't saying you should do it that way, I'm saying that a plant will still grow under those conditions. Weed is a weed. I just like the ease of just throwing it in a tub of water and forgetting about it.
But, you learn something new everyday. I'll make the growing medium damp for my next try. I'd like the best results if at all possible for a fool like me.
I'm starting a new growlog if you want to help add some pointers. :thumbsup:

One big happy family...I just hope we all learn and grow together, spiritually and become better people as well as better grower's...
I appreciate the fact that you challenge methods/concepts.
Reminds Me of ME...LOL goodluck, holler at me, when you post...Lots of good happy growers helping each other out...Here at Cdot

I also, have said many times myself..."It is a weed!!!"
Just let it grow...The KISS method works best most of the time.

PS...I am not always right...there, I said it...lw

What sized airstones would you dudes reccommend for something like a 20 gallon rubbermaid plastic box? I plan on using the Elite 802 airpump.
Thanks for clearing up that for me, much love to all of you guys.

I would use the air tube things. They work great and never clog or need replaced.
