Which would produce more DO in a DWC?

I'm repurposing my old tent. I'm using the bottom half of the frame for my nets, and secured some mylar from the tent. It makes a huge difference.




Next I'm going to be replacing the existing ducting going from the hood to the fan, then to the ceiling with insulated ducting, since I'll be adding a 600w hood for suplimental lighting, so there's going to be some extra heat to account for. Using insulated ducting makes a huge difference. Feel yours, and if it's really warm/hot, it's just adding heat that you have to right.

Added my extra 600w hood. Makes a big difference on the footprint! It's probably going to be near the end of this grow before I get the QBs, so I'm just going to be using this setup till the end.


Swapped out the existing duct for insulated. With the new duct in place, the temps barely flex, with the addition of the 600w. The 6" fan is usually set between 10% and 40%, depending.

I've got the 600w on another circuit (extension cord running across the mylar). Running it with the 1k trips the AHCI breaker. The one on the wall is tapped into the kitchen, on the other side of the wall.

I've got a 6" fan mounted to the wall, below the pump and ballasts. It really helps dissipate the standing heat, which I would think helps keep the room cooler. I mentioned it earlier, but I can't emphasize how important it is to clean the fan blades, and cage, often. Like every few weeks, or even more if you're in a dusty environment. It doesn't take much dust buildup at all, to get these fans blowing nothing. It's so simple to pop off the front cage, and blades.

White Widow, around a week and a half into flower. I don't do a real SCROG. I use the nets to spread out the branches, as well as holding a good portion below the net. But I don't keep tucking the branches below the net. I let everything grow up from there, and then I'll have another net at the top, to hold the colas up. I may have to go a few inches down.

Hey Hey....I've got the same 2 inch fittings. Any leak issues? Did you use gaskets or O rings?

Nope, no problems. The 2" bulkheads that come with gaskets, seals without having to use any sealant or silicon.

What spacing did you use between trellis levels? Looks great.

Thanks. They're round 14" apart.

Maybe more like 16" to 18"

If I can't smell things in here, I definitely have the virus

Continuesly down right nice mate, have a good weekend...

Not bad for a day's work...

The valves and everything are still really easy to get to. I also still have room to work in the tent from the side flap. That was something I wasn't willing to give up. I've got a bad back.

I need this design do you have a list of everything I might need and is it possible to make it 5 plants other than 4

Just start at the beginning of this thread. I got through every step, with lots of pics and details.

Another great site is the growweedeasy site

No, I use the house air to keep it at 68 degrees. Very easy to do, and very inexpensive.

I refuse to get a chiller, but I'm determined to keep my water temps down. Last few hydro grows I used frozen jugs to keep temps in check, and it worked great. However, it's kind of a pain. I also had a small fan blowing across the surface, which also helped keep temps down via, evaporative...

Okay I will

Almost there. Maybe another week.

The odd one in the corner, which ended up producing enormous buds, was harvested last week. The three remaining White Widow are taking their time, but are getting really close. I'd say within the next few days.

I wanted to show some more pics of how I repurposed my old tent.

Blocking light from getting into the containers can be a bitch. Since tent material is lightproof to begin with, and has a reflective mylar side, I thought it'd work good on top of the totes. It works even better than I thought. Also, my reservoir ended up with some black mold, and other nasty stuff. I was using a tent previously, and my reservoir was in a dark corner. Now that I'm growing in the open, I forgot to protect the reservoir from light. Luckily I didn't have any issues, but this time I'm taking steps to prevent that. Again, using my old tent.






Alsoz finally decided to use actual blackout window film, rather than stapling up sheets of black poly. This works really well, especially since the other side is white, and doesn't get hot with the sun hitting it full on for most of the day. Used black Gorilla tape to cover up the edges of the window film.

I didn't realize this wasn't undercurrent, and just straight DWC.
The main thing I liked and used R-DWC for was having a control bucket/res for easy measurements, additions, changes, and constant mixing of the solution. And even being able to have that control/res outside of the room/tent or whatever.
DC water pumps are extremely low power consumption compared to mag-drive/similar and barely heat up the water at all, nowhere near the standard mag-drive (like danner, etc) style ones do. Same reason I used diaphragm styles air pumps instead of piston style, heat mainly.

There was and probably still is a thread at ICmag (biobuckets), one singular waterfall, at the res - no other aeration at all from what I remember. Great results, no issues, I build a few.
Now that I know about ORP meters I'm very curious to actually test some of this stuff out because I'm yet to see someone quantify DO from either or, though I haven't looked in a pretty long time...long time. I bet the aquarists have though.

This looks like a RDWC system to me.
