Blazeoneup's Recirculating Dwc Construction Tutorial!

The plants overgrew the space was my biggest problem lol, I should have installed a trellis. Other then that I would use panda plastic( the black white poly sheeting) to block light through the lid as I got a little algae.

Does anyone discuss topics on this anywhere?
I've been slowly switching my ebb & flow tables in the flowering room over to buckets.
I've started with two buckets and the first thing I noticed was when I put a big plant in to the last bucket, I came back later to find the water level in the empty bucket very close to overflowing.
Something going on with levels and pressures that I am missing.
Any similar problems?
The other thing I would like to discuss is finding all the proper fittings and whether I need shutoffs on every connection so I can disengage any time, any where in the string.

I'm using this setup and I have a question. When I change out my solution and mix the new water/nute solution in the reservoir, is it okay that my float valve (same float valve as depicted) releases the water so slowly? I have 4 buckets plus the controller and I'm concerned that the roots may have issues waiting for the water to fill.

I never mixed nutrients into the reservoir, I mixed into the controller, I used the reservoir to top off with ro water through-out the week. You don't want those roots drying out. As long as it fills up fast enough your gonna be fine. But if its so slow that the roots start drying out you have a problem.
Add a 3/4" fitting to your reservoir and add a 3/4" shut off valve to that and run a line from the shut off valve on your res to your controller bucket. This will allow you to bypass the float valve during nutrient changes and then the float valve will work as intended to top off the system through the week. GL
Wonderful! Thanks for everything.
WOW, Quite a thread. Thanks Blaze and all the thread Jackers for all the knowledge. Informative and amusing at times. Setting up for my first grow. All I know at this point is it is going to be wet. I gotta say I Love the whole RDW setup. And at this time it is time proven. Only a few mods needed. (Like the 1/2 to 1/4 tee) Any chance to get the download able verson? Tons of great info! I find it amazing that a thread started in 2006 is still viable today. Guess it shows that good info and a well thought out designs are priceless!
Q Blaze Would you use the same system today? Or perhaps go with the Recirc drain tables that are so popular today?
Gruetoo

BRILLIANT- IT'S A BIT TO COMPLACATED 4 ME THAT IS,I WILL JUST STICK TO THE FLOOD AN DRAIN AN THE (IGS DRIPPER SYSTEM) THEY DO THE JOB AS LONG AS THE END PRODUCT STINKS AN IT'S A GRADE-A QUALITY SMOKE,WHO CARES ABOUT FANCY DWC SYSTEM.

WOW!!!! Great thread!!!!! Thanks for all the info.
Leaks in feed lines
Leaks in feed lines
Just put one of these together for a friend last weekend. Was pretty easy for the most part and when i fired it up for the test almost every single 1/4" barb inserted into the 1/2" feed line started to leak at the base of where the 1/4" barb gets poked down into the 1/2" feed line.
I shut it down, dried everything off and marine epoxied everything. I came back the next day and the leaks still were going nuts right at the base of the 1/4" barbs. Any thoughts on how to fix this? Marine epoxy and silicone aren't cutting it somehow. Maybe i just did a shit job? should i just re-cut the 1/2" feed lines and try again?

KarmaDank - I'd try it again, are you using the tool they have at the hydro shop to make the initial hole? They have a punch out for making the holes. Also when you insert the barbs try to push it straight in not at an angle.
Now that's service! Thanks for the quick reply, i guess I'll give it another go. I was just using the tip of the cooking thermometer but it was kind of a struggle getting the barbs in the hole. I feel like i could have been too rough getting the barbs in there and widened the holes too much. Oh well trial and error, I'm gonna re-attempt it on Friday.
GL I used a cooking thermometer before as well, I prefer the hole punch though. I know it can be done with the thermometer though just easier with the hole punch they have at the hydroponics shop.
GL I'm sure you will get it the second time around. Hell You could even use an end cap and a spare piece of tubing to practice on and then hook a pump up and test for leaks.
Hi I really loved the whole thread which I read today every post. I am in the proceeds of building a DWC before i read this post. It was good to see that what i was going to do was exactly like yours blaze. But I did notice a couple of post from someone that put the return line in the top and feed from the bottom (well i guess you could feed from the top but put the line down the bucket) I have thought about this and can see some benefits
1, No clogging outlets and
2. No chance of overflow.
3. Plus outlet water can waterfall in the control tank
Before I go ahead and build this system do you have any thoughts on this.

Screw punching a hole in there I had that issue too when I was building these for some friends. Melt holes with a fine tip solder iron perfectly round hole no tears causing leaks like with the hole punch. Don't press down hard it melts fast enough that you will go through a light touch is enough.
Incredible thread Blaze..You are a good soul to share your wealth of experience and help so many.I just started my first dwc after wanting to try it for ages.So far so good.It is exceeding my coco by far in terms of speed and health.
my question is if i were to use 5 gal buckets(four) under 1k and keep my room the tent is passively vented from at 65 degrees..Do you think I'd need a chiller? I plan on getting one and setting up a controller but until then..do I stand a chance? the chem d being vegged now is maybe 14" and has a lot of roots.I'm concerned that as the roots continue to build up(which they are doing pretty quickly) the lack of volume available for h2o will make the temps rise ...Much thx again

Amazing thread, thanks so much for all the detail and hard work. Quick question,
I read that RDWC systems permit significantly lower total nute concentrations (as little as half of norm) due to the added DO and root zone health / micro beasties aiding in uptake.
Early on it points to 1300-1500ppm max at mid flower stage.
What am in missing?
