Bad Habit's 7.5'x11' Shed Buildout

Dank Demon

Growing herb is a way of life!

Hey Bad Habits, could you not separate the external ac intake and out take by using a slim piece of wood or metal between the vents to segregate the air one releases and the other draws? If you see what I mean that way you do not need to do anything internally just externally? Or even just using some slim line box section just placed under one of the external metal ducts you already have and running along the outside of the shed to another location?

Peace
 
Alright, it's really about time I up dated this thread. I had family from across the country visiting so I didn't have any time to work on it, but I'm back on track now. Hopefully will be ready to have plants move in by the weekend :dance013:

Thanks man. Its much appreciated. From what I can tell, I love your work too hehe :D

I think everyone will have a decent chance of getting something this time.. crossing my fingers they get there okay..

Keep up the good work!!

Thank you sir :tiphat: Bummed about your decision to step away from providing the beans, but I'm sure you know what's best for you. Keep doing what your heart desires :joint:

Hi Dank, thanks for droppin in again. Unfortunately it's too late to seperate the AC intake/exhaust as it's already in place and sealed in. Plus there were studs in the way of moving them out more...

The good news is I have done some heat tests with 4 of the 6 lights on and the AC has kept the room at 78-80 while set at 70f. You can set it as low as 60, so I think it should work out alright.
 
Okay, some updates!

Installing a PVC female garden hose connector onto the tray.

A garden hose will screw into it, which will then be fed into the condensate pump which will pump it all outside of the shed. No more manually removing totes full of run off! :dance013:

The first one I tried PVC glue to attach it, but it didn't seem the best. Next one I went with only caulk which seemed to hold it in pretty well. I still have 2 trays to do, and was contemplating using JB weld instead. Only thing is JB weld is some pretty strong shit, so I was worried it might cause some off-gassing? Anyone have any idea?

Taped some screen over the tray discharge outlet with water proof tape so no pieces of perlite get in the hose or condensate pump and clog it up:

Garden hose screwed in:

I made a major goof here. The condensate pump intake holes are 4" high. When I designed the tray supports I decided to have the discharge 2" above the pump intake holes (6") so there would be enough decline for the water to passively drain into it. HOWEVER I completely neglected to take into account the fact that the PVC adaptor and hose itself takes up another 3 or so inches (hence the hose sitting on the ground in the photo)... :laughing: The good news I dumped 5 gallons of water in the tray, and despite it having to go uphill in the hose it still makes it into the pump fine and gets pumped out... whew!
 
Condensate pump behind the AC with the garden hose going into it:

I still need to plumb the tray on the opposite side of the room into it.

Here's what it looks like coming out of the shed:

picture.php


I made a ghetto P trap to keep bugs out by bending the hose and tacking it up against the sheathing with zip ties and screws, and caulked the edges around the hose coming out. The garden hose then screws into a irrigation hose (the kind that has a bunch of tiny holes in it) which helps disguise the water as it comes out. When the condensate pump turns on it really shoots it out, so if my neighbor randomly happened to be looking over my fence (pretty unlikely, but you never know) when it discharged, it would certainly look suspicious. This way, you can never tell when it discharges because the hose just releases a little bit through all the tiny hoses in it.
 
Before I was having issues keeping the T5s level, because I was suspending them from zip ties in order to save vertical space that the original wire hangers take up. I came up with a solution:

picture.php


These are the hangers that came with my hoods that I bought for my flower room. I didn't use them on the hoods in there in order to save vertical space in there as well. Here I just stuck them in through the vent hoods and secured them with 2-4 sheet metal screws. No more balance issues.

Gettin some cords outta the way:

picture.php


Hung down some wood to put my clip on fans on (picture was taken before I added the V-hangers on the lights):

picture.php


The fans are fairly dinky, but because I am really squeezing all the juice I can outta the amps I have in this room I opted for these smaller fans as they don't use much electricity at all. Hoping they are enough - I have 2 per 2x8 tray. One nice thing about them though is you can adjust them up and down as needed unlike wall mount fans.

I redid the back one so as to make it easier to move the T5 up and down without having to take the fans off every time:

picture.php
 
Installed the 6" hyper fan and ducting from the flowering cab, which will draw air from outside the shed via the passive intakes on the bottom level, then up through the top level via the PVC pipes and finally through the exhaust:

picture.php


To help reduce noise I added a duct sleeve over the aluminum ducting on the exhaust side of the fan, and put some fiber glass above as well on the ceiling to absorb more vibrations from the fan. When I put the duct sleeve on I pulled it over the fan (just the thin shiny part, not the fiber glass part) so the fan is pretty covered - I hope this isn't hazardous? Not the best pic to show how it was done unfortunately.

Installed rollup doors made from reflectix and velcro on the flower cabs:

After I took this pictureI added another 45 degree turn with ducting on the end to ensure it is light proof.

very cool. I love the attention to detail. very well thought out. looks like you have done this a time or two :D

I've seen friends invest 100s of thousands into big grows where they didn't think every detail out which resulted in massive growing pains and countless headaches. Being able to see friends go through this instilled in me it's much better to do it right the first time rather than the do-it-as-you-go mentality.

Also I hate having to do modifications as you go. For example, I could have already had plants in the trays, watered them, and just shop vacuumed it up. But since I want it to be automated I'm plumbing all the trays to discharge outside... I could have added the discharges after, but with a room full of plants that would be a big pain in the ass. Not to mention all the light poking through the holes to the outside when I had to actually drill it Just things like that. Some people might think I'm overanalyzing scenarios like that, but IMO better safe than sorry.

And this is actually really only my 3rd build. I grew in a closet/a few cabs for a few years, then I built my main flowering room in this house, now this. So really not a whole lot of experience honestly.

Thank god for ICmag though and being able to do tons of research, for free! :tiphat: The user The Gnome was very instrumental in getting my flowering room built. I figure it's the least I can do to type up my builds to share with the community here, as I know personally reading threads like this which are pretty much step-by-step were extremely useful to me when I was doing my researching. The knowledge passing continues. :smoke out:

I really like all the time, thought, and most especially effort going into this. I can't wait to see this fully operational deathstar with some plants in it. :yes:

Thank you sir! My motto is if you're gonna do something, do it right :biggrin: That being said I'm definitely way behind schedule... this thing should have been finished weeks ago :laughing:

And your wish is my command... pics incoming! :tiphat:
 
Got the the carbon filter hung up:

picture.php


This was NOT fun to do. I think it's a can 75 and it weighs a million pounds, which is not particularly easy to lift up even with 2 people. Definitely couldn't have done it by myself, that's for sure. Used some heavy duty bungee cords and hooked it to both the roof spine in 2 places, and to 2 ceiling joists in 2 places just to play it safe (although I'm certainly no structural engineer - I have no idea if this spreads out the weight distribution and is better for the structural integrity of the building or not lol). There's is a duct silencer on the other side as well, which I also wrapped in reflectix because I had some extra leftover it has a small R value to it as well.

Here I am framing in a light trap for the entrance:

picture.php


This accomplishes 2 things: when opening the door at night there isn't a huge flash that looks like an alien spacecraft landing through the neighbors window, as well as helping to keep bugs out at night as well as they won't swarm in when I open the door since it will be dark when you step in.

I framed in a triangle to help save space on the left side of the picture so I can later install a water filter/rezs there. I had left over orca film from my flower room build so I have the white reflective side facing the inside of the room and the black side facing the door. I just need to hang the final piece where it is still open (there is orca film on the top and left side in this pic although it's hard to tell.

Demonstrating the drainage from the top tray to the bottom tray:

picture.php


It's not a great pic because my back was up to the wall so couldn't get a very good angle. But there is a garden hose connected to the PVC adaptor in the upper tray, which is then tacked to the wall with zip ties and screws and then drains into the bottom tray, which will drain into the condensate pump.

Some Obama Kushes in 2.5 gal pots:

picture.php


These were growing straight up into the lights in the previous veg closet. As you can see, they are already almost up into the lights here as well lol. I need to top them again, train them, and then transplant them one last final time. They are a little stressed out in this pic because I hit them with triazicide yesterday before moving them in an attempt to keep any unwarranted pests out of this room.

Some GSC in 1 gals in the top tray:

picture.php


Need to transplant these, then top them and train them as well.

Things left to do:

- Finish the drainage plumbing on the flower cab side
- finish the light trap roll up door
- get the dehumidifier in (currently just using the ACs dehumidifier option at night, got a new 50pint friedrich unit today ready to move in)
- install a small or tall boy water filter and get some rezs in there. Only thing is I'm not sure if I have any juice left to spare for the pumps that the rezs would require, so I will have to do some trial and error. Either way hand mixing and hand watering from a rez in the room would be much easier than lugging it from the house - outside - into the shed.

Cheers!
 
Freakin' awesomely detailed thread! The grow is awesome too; clever as hell and clean to boot. Anyway, your goal is to run drippers, correct? and dtw?

I couldn't find what you were using for nutes. If you're using amended soil, rather than nutes in your sol'n, you can just use line pressure to run irrigation water directly to the irrigation tubing (after the filter), and skip the res. You will need a flow limiter if you do this, or your irrigation tubing will leak like crazy/fly apart at the joints. I use this system to automatically water my vegetable garden in the back yard, it works great and I'd use it inside too if I didn't run nutes in my sol'n.

Also, if you're running drippers you can probably get away with a pretty darn small pump. What's the required lift, like 4'-ish?

If you run the pump to a Tee in the middle of the table, and have your two irrigation lines at 4' each instead of an irrigation line with an elbow on one end with an 8' irrigation line, the pressure will remain more even. Also, if you use 1/2 gph emitters instead of 1 or 2 gph emitters, it will keep the pressure in your irrigation line higher, and you can run more drippers on a smaller pump. Also, the flatter the irrigation line, generally will give you a bit more even watering.

Oh, you could also use nute injectors (they're freakin' sweet), but that would be insanely over-priced in this instance.

Note: When I say irrigation line, I mean 1/2" (or whatever you are using) tubing, not the final 1/4" drip tubing.

That light trap is a very cool idea. I'm having a hard time imagining how that works though (i'm not a bright man). Are you opening the door, Stepping in, closing the door, and then opening another door to enter?
 
hows it going with the awesome grow shed? I wanted to know if you ve had much time to test out the sweet pvc cooling/ventilation invention? Im guessing that with the doors rolled up it would work from top to bottom but it doesn't matter as you always have the doors down right?
Thanks man I like your attention to detail and when you explain how much of a pain it can be fixing on the fly, your right
