DWC white russian,got some questions.PICS

[elito]

Iv been growing in soil for over a year till about 2 months ago i started an ebb and flow hydro grow,now i got the same clones in this ebb and flow and in some pots in soil and two clones in dwc i put straight to 12/12 soon as they developed some nice roots i wanted to see can i get a nice size plant without veg.time,these two clones in dwc outperformed all the other plants they are 24 days in 12/12 and they developed more than 38 day old plants in soil and 29 day old plants in ebb and flow thats a mesurment from the initiation of 12/12,so i wanted to ask some of u guys with more experience why is it so,maybe couse i have a dual air pump u would use in a 60 L tank i placed it in a 14 L tank in witch these two plants are growing now,if thats the reason then i might convert my ebb and flow tables to dwc and put 10 dual air pumps in it

Its because dwc kicks ass

 

[MAZEinaHAZE]

DWC focus is too grow big fuckin root systems. With solid roots, comes big plants.

can u tell me how much air if enough to have results like these i got,i wana run a 350-400L table with 98 clones i was thinking 8 or 10 dul air pumps,is the air that important

 

[FreezerBoy]

The secret is massive amounts of oxygen to the roots. Especially the upper roots which live above the water in a DWC

People forget (or don't know) that beyond anchorage, food and water, roots need to breathe. Not CO2 as the upper plants need but, O2. The upper roots are the air hogs. Plant too low and it will stall for a few weeks as it sprouts new roots at the surface. Some non-mj plants are so hungry for air they grow their air roots above the ground.

Gotta learn to type faster. Air is everything. Personally I use a pump rated at 60 gal for my 12 gal res.

While warm water doesn't have to mean rot or death, cooler water (say 68ºF) will hold MUCH more DO than warm water.

can u tell me whats the rating on the pump u use in a given system like i use a 7L/min air pump in a 4 gallon reservoir thats for the plants in the pictures

 

[FreezerBoy]

My Whisper pump (which is actually rather loud) doesn't give a liter per minute spec. The box simply said for use with up to 60 gal.

 

[elito]

do u think the ai bubbles made the big difference in this dwc compared to the ebb and flow or something else

 

[FreezerBoy]

I don't know it's the bubbles per se, it's the surface turbulence they create that causes aeration. The more your disturb the surface, the more oxygen in the water. Oxygen in the water keeps submerged roots from drowning but isn't the secret to increased growth.

Fresh oxygen to the upper roots, the air gap, is the key. Aero and Foggers report even greater growth as the root mass exists almost entirely in mist.

As E&F supplies better aeration than soil, so does DWC, Aero and then Foggers provide more than E&F. Unfortunately, due to the mechanics of each system, the greater the growth potential, the greater potential for disaster. Lose power in a soil grow, plants last for days, maybe a week. Lose power in a fogger, I don't know it would last the day.

 

[narutonut]

Absofrickenlutely!!! I swear by DWC mate and the bigger the volume of air (to a point) the healthier the roots will be. I didn't see anything above about a rez chiller and lots of air in each pot will help to keep root temps low as well as supercharge them with fresh O2. I run a 35w Sunleaves ($75) pump with a splitter and place 2 x 1" air stones in each of my 6 buckets. The surface of the water in the buckets froths like making a cappuccino. plants grow huge healthy and rot free. A great harvest every 8 weeks.

Upgrading to this in the next week or so, currently my 3 8 outlet ecoplus air pumps are a combined total 80L/min.

450L/min! I am sure my girls will appreciate it if they don't lift of to the moon. DWC rocks, RDWC is even better, I will go head to head with any other grow system with RDWC. You can literally watch them grow.

Check out the rate of growth here in RDWC, now take in mind they were on 300-450ppm the whole time in veg waiting for others to catch up, so with a proper feeding schedule it would have been faster.

 

[redspaghetti]

Nice time line PK!

 

[narutonut]

That is one thing I totally forgot about. The nutrient usage by adding lots of O2 to the root structure is exponentially increased. What this means to those that need to feed the gaping maws of the green beasts in their garden is that you spend less on nutes because your plants use it all more efficiently. In my flood and drain system i Veg at 950ppm and push 1900ppm in flower but with my DWC system I flower at 700-900ppm half the concentration or less than normal. I quit using DWC for veg because I kept overgrowing my room when they got to flower! Oh and when it comes to DWC vs RDWC RDWC is always king. My system and res exchange 100% every 45 minutes which leads to easy control of all bucket's PH/PPM/Temp without ever opening one (except to check air and feed lines).

 

[Think Green]

Dig the dwc. I run 5 gal buckets, but thinking of switching to 2 gal buckets to save room.

 

[elito]

my soil plants are at 1.6ec wile the dwc WR are at 2.2 and they seem to love it might even get it higher,i wana convert this table into a dwc SOG can somebody tell me how dificult is it to mix nutrients in a single big reservoir like this,in my ebb and flow i can use a power drill with a mixing fiting to stir the water to mix the nutes and get accurate readings of the PH and EC,do i need to get a pump in there to stir the water to mix it or will the nutes desolve on their own

 

[choch]

Done lot's of dwc but never on a table. In whatever system I use I always mix the nutes in a separate container and ph adjust before I put the roots in it.

I'd be tempted to have a pump in there like you suggest to stir things up anyway though. Might need to be on a timer if it adds too much heat.

Hope someone with more specific experience to your situation can give you better advice.

I'd suggest RDWC for that. A 2 gal bucket will be lucky to hold a single gal of water. The smaller the res the faster the disaster and a less than 1 gal res is tiny.

this table holds about 360-400l of water thast when i leave 3-4cm space between the pots and the water surface,i have 5 of these tables so i wana use em it took me too long to get em in this building and set em up to just throw them out now,can u direct me to a site or thread on RDWC i never analized that dont know even how it works
