Closet Doms in Water.... An Ad Hoc Log of Black Dominas in DWC Hydro

Yeah that's what mine has too. Im using it for my 400w mh for vegging and I REALLY like that reflector. ;)

WH, if I remember right, you have the lens and a fan on yours? Or just a fan? How does it help the temps?

I'm half way thu installing a muffin fan right now...

I think jorge cervantes mentioned in his book that that particular reflector was one of the best deals in North America....which is saying something in my book.

I use both the glass and the muffin fan (dayton 4 inch....105cfm) but I originally bought the glass back when I used that reflector for my 1kw mh and hps so I was asking it to do a LOT more back then.....which it did very well with a four inch 279 cfm inline fan.
The 400wmh is MUCH less hot than a 1kw (of course) but a 400w/hps will run even cooler than that. The difference between your setup and mine is the space. I have mine running in a huge room so the heat buildup is pretty much nil. I dont at ALL know what it would be in a small space like yours. Are you planning on venting into the room itself? That's what I'm doing.

The room itself is vented thru a 6 in 449 CFM Vortex inline fan that is hooked up to the carbon filter. The whole closet itself is 7 ft wide x 2 ft deep by 8 ft tall = 112 cu. ft. The room is an additional 12 ft x 13 ft = 1152 cu. ft., which means my fan can clear the entire room+closet in under 3 min when run wide open. I usually have it throttled back to 60 percent or so, which means it clears the room in about 4.5 minutes.

My only concern for heat is directly under the light where I have noticed ambient air temps run 80-85 degrees at times. Much of that has changed now that I am running my light during evenings to keep room temps warm at night and moderate during the daytime hours.

I saw in Opie's SCROG (LSTTT thread) that he has a fan directly under the lamp blowing up onto it, so maybe I'll spec that into my build and use that as an additional measure if needed...

Yeah, I love Jorge Cervantes book as well as Greg Green's book too. They get a lot of use around my house. For any beginners or intermediate growers that are following this thread, I highly recommend them in this order.

Spent some time workin' with wood today... building the screen of course. First I built a frame out of fir strips (1x2 roughs for those unfamiliar),
[attachment=o170610]
then measured my 2 in x 2 in screening to fit the frame. I went and test mounted the frame first so that if it didn't fit, I was ahead of the game cuz I did not have to remove the screening to fix the fit problem.
[attachment=o170611]
No fit problem at all. Next I used my staple gun with 1/2 staples and secured the screening to the frame before test mounting it again in the closet. I decided to attach mounting strips to the closet, then set the screen on top of the mounting strips and attach it with 2 screws... I'll do that once I vacuum up the mess and install my glass lens on the light.
[attachment=o170612]
This is what it looks like with the screen in place. I am going to make a 'stadium' screen for the 2nd level (approx 8-12 in above the 1st screen) once I get the glass installed on the light and do my final cleaning/sterilization of the space.
[attachment=o170613]
So... that is about it for now. If there is anyone lurking out there I would like to know what you think so far and if there is anything you wanna know about the setup.

I know it is not a true SCROG since I did not veg the plants with the screens in place. In real life shit happens and my last grow had nute deficiencies that screwed up my schedule, and... wa la... I am now gonna finish by flippin' to 12/12 and doing my best to finish them as you see here so far.

If there are any Scrogmasters out there who wanna warn me what I am in for by doing this, I am up for it.

MVP :jointsmile:

Today was a big day. I got the closet all cleaned up and monkeyed around with the fans and ventilation and stuff. Then I decided it was time to bring the girls into their new home. Before doing so I got them situared in their new DWC grow containers.

These containers I made from 10 gal. sterlite storage totes, 3/4 ball valve plumbing, and covered them with aluminum tape to seal out ALL light from the reservoir.
[attachment=o170725]

I then cut 2 holes in the container top - one to fit my square 6 in net pots, and one to fit the round 6 in net pots. My reason for doing this was simple: to afford easy access to the res for PPM and PH monitoring. Also to have flexibility when I wanted to use one type of pot over the other (so I didn't have to waste cash and buy multiple lids).
[attachment=o170726]

Now each DWC bubbler has its own 14 inch airstone that is run by a dual line air pump rated for a 30-60 gallon aquarium setup. I used a "T" just inside the res to bring both lines together and power the airstone. As you can imagine, plenty 'o bubbles.

Lastly I prepped the girls into their new containers and went on to finish up a few final details on the grow space itself...

Ahhhh, there they are in the HydroHut, getting ready to move to their new place...

The deal is that I cannot remember exactly what I posted, and when the site went down last night I retreated to the garden and did a little bit more work. I'll have to update quickly cuz I gotta run errands in a few minutes.

Moved them into the flowering closet and test fitting the 'stadium' type screen.

Here they are in the closet for the first time. The air lines and electrical cords are a bit messy, but I am gonna clean those up this afternoon when the lights go on.
[attachment=o170780]

When I was test fitting the top screen I had to bend it around a bit to get the fit I wanted. Once happy with the fit I attached the screen to nailing strips with the staplegun. I then mount the screen to the wall by screwing drywall screws into the wall studs in the closet. That way if I ever need/have to remove the screen it is as easy as removing a couple of screws (as opposed to stapling it into the closet and having to rip it out)...
[attachment=o170781]

The next two pics below show the screens in place after I attached the nailing strip to the wall and spent some time tweaking the screen and bending it into place to my liking.

Next update this afternoon sometime..... thanks for stopping by

Wow that looks great MVP! Can't wait to see those babies start spreading out through that screen. Too much work for me....but certainly would like to have the results from all the energy youve put into them. Think you'll have a GREAT harvest here! :thumbsup:

Ps....Good photos too....even I understood what you were doing. :D
