Which would produce more DO in a DWC?

I thought I'd show how, and why I went through the extra lengths of isolating as much noise as possible.

I mix and record music at home, in my home studio, which is right across he hall from the grow room. My studio is dead silent, especially after I relocated my PCs to a non-adjacent room. In the grow room have 3 inline fans, a 70lpm commercial air pump, and a 400gph water pump, all going at the same time, but the room is virtually silent as soon as the door shuts. Even in the room, it's much quieter than many.

First thing I did was to hang my air pump, and suspend my water pump, so that no vibrations were making it into the walls. I then surrounded my air pump, and a fan I usually have running higher than the others, with dense foam sound isolation wedges, used for bass traps in home studios. If I had bass to trap in the grow room, I would have wedges in each of the eight trihedral corners of the room, where they are most effective. Since I eliminated any bass that would have been caused by the pumps, all I needed to do was surround the air pump with the blocks to absorb the high and mid frequencies. The foam converts absorbed frequencies into heat, but not anything that's noticeable. The water pump is tucked behind the reservoir, and is suspended in air by the pump manifolds, which helps isolate noise from that pump. Because there are a lot of hard surfaces around the pump, I could add padding to capture any reflected waves, but there's not much space, and the pump would probably start heating up. I'm able to keep the air pump at room temperature by having my tent exhaust fan blow on the pump. This really extends the life of the pump, helps keep temps down (especially the air going to the stones), and it allows me to really surround the pump with blocks without worrying about temps.

I've just got the blocks shoved up there, but I plan on cleaning it all up.


Here you can see how I have my exhaust fan blowing on the pump, which is suspended by hooks from the ceiling.


My studio across the hall...I finished building the desks, and setting up the room a couple months ago.


I love my 25" ultrawide monitors! :)


Sorry, just wanted to show off one of my hobbies outside the grow room. :)

Nah, they aren't too bad, especially with a few steps to quiet the overall noise in the room. Even tho those foam blocks are surrounding the pump, they are actually absorbing sound from the entire room. I have a seal on the room's door, as well as a heavy duty sweep. As soon as I close the door, it's virtually silent.

Thats a good idea, plus you then have smoke at least 3-6 months cured, depending on your lung capacity of course, which in my opinion is worth the wait, in general 3 months cure is what I aim for in the future...

Like you, I take curing seriously, and take my time. I usually won't smoke any earlier than three weeks from harvest.

I wanted to mention how much of an impact just adding a door seal and sweep has at reducing noise. Short sound waves/high frequencies created by fans, find thier way out through cracks, crevices, and vents. The walls, and even the tent, can contain those frequencies in the room quite a bit, but any place they can make their way out of the room, will be very noticeable. Those higher wavelengths bounce around the room, and amplify quite a bit.

Vents are really bad at noise leaks. For those, sound isolation boxes, and/or insulated duct can be used to cover the vent.

Door seal:


Door sweep:


It is really important to seal as much, and as tight as you can. Any little leak will be heard. The door is more difficult to close, because of the seal, but it's reassuring that the door is closed tight against the seal. This also helps keep bugs out of the room.

Got this Jack Herer being groomed for the outside. I'll be moving her out into the yard in about six weeks. I'm trying to get her spreading out wide, so I've got her in a sizable pot. Not sure if it's the same with cannabis, but with trees, the width of the tree is generally the width of the main root structure. So I was thinking this might promote her to grow outwards. I do have a few of the branches anchored down, and have both topped twice, and super cropped.

Wanted to once again, show how I keep my water nice and chilly, without a chiller. Just blow the air from the vent, on the surface of the water.






Here are my two Jack Herers, filling up the space of four. I swear these are two different strains. The one on the left is definitely sativa, and is most likely the real Jack, and the other looks more indica.

The water is actually cooler in the summer. In the summer, the AC air blows onto the water, which is around 60 degrees. In the winter, I use my closet inline fan to draw house air, and blow it onto the water. I usually keep my house around 67 in the winter, which is what blows onto the water. So, in the winter, my water temps stay at 69, and in the summer, it stays at 66. Those temps don't fluctuate at all.

Sorry if I posted this before, but O2grow has models from 1 +++ emitters (one for each bucket)

I finally resolved my root rot issues and have been using only a 2020 O2G for about 6 weeks (no agitation , circulation, or splashing), and it really works

Alas, no cannabis growers are running threads with them, so I had to learn on my own, but in the end what I learned was my root rot issues had nothing to do with the O2G and everything to do with air pumps/stones, although in many past grows air pump/stones served me well

Watch your threadjacking, please.

I'll also mention, as I have before, that this is the original fill. I don't flush at all, unless I smell something funky, which is a good indicator of a problem. My roots are pearly white, with no additives.

Something that I think may be helping is the massive amount of bubbles under each plant. The bubbles have more than enough force to get the roots all spread out. So getting DO to all parts of the roots is effortless. Not sure I could say the same if I was just running an Undercurrent.

Just some pics of my current grow. On the left is Jack Herer, and on the right is some mystery indica, that was also supposed to be a JH.










Once again, I've got my hood strapped to the top poles. I just strap the yo-yos around the vents, then I can ratchet the hood up high, easily.






66 degrees, with no chiller! I wonder if anyone else did this with theirs. If so, give me some feedback. It's such an easy way to keep the water cool.
