Quantum Tower LED PC case: 46w of SDOG

Hey GP7, thanks for stopping by, your links are great!! :wave:

Happy Friday everyone :dance013: I finally got some free time to work on my cab and build the scrubber I had in mind, as things are starting to smell a little.

Here is the new improved PC case. I was getting tired of sliding the case around the floor (and scratching it in the process) so I added some Lian-Li case wheels and a handle. They have a lock so my garden won't roll away on me :cool: I was not content with zipties holding my expensive lamp up, so I bolted it to the top of the case and added a filtered fan as an intake to dump fresh, cool air on it (very low CFM of course). This improves temps and gives me more vertical space.

Previously I had disabled the PSU fan and kept it as a passive intake. Still, it was getting pretty toasty so I broke open the PSU, soldered together the power and ground leads of the motherboard connector (so it always turns on) and removed most of the excess wiring save for a 12V molex lead. I plugged the fan back in and covered all vents except the one on the side, which now acts as a fresh air intake and doesn't pull from the grow room. I had to saw off part of the PSU extender (another Lian-Li case mod, who knew??) off but it turned out well and it stays nice and cool now.

I was tired of plugging/unplugging each array to turn it on and off, so I wired a couple switches up, cut a few holes in the 3.5" drive bay cover and now can turn them on and off without opening the case.

My wife calls it The Robot. I tend to agree.



Here is my scrubber. I based it on the CAN designs and other great DIY tutorials. It's basically a 120mm to 80mm fan reducer, some 120mm rubber vibration pads (for an airtight seal), an 80mm duct, and a couple pencil holders with nylons ziptied to them. I cut a hole in the bottom of the smaller holder and glued a mesh 80mm fan filter to it. Sticky caulk seals up all the little gaps. The Noctua fan does a good job pulling through the 20mm/.8in layer of carbon, although piggybacking two gives double the pressure for a higher airflow if needed.



One thing about LEDs is that you don't have to water nearly as much... and I found out the hard way. Unfortunately this has set my SDOGs back about a week in growth after transplanting to a bigger container. The runt I thought would never pull through but it's still hanging on... it has a wonderful earthy/spicy aroma so I hope it lives... the others are a mix between fuel and candy sweetness.

I feel a little ashamed for neglecting the babies :redface: but there is some healthy new growth so I'm optimistic.
 
looks like something wrong with your medium, not just overwatering. you in soil? personally I recommend coco. looks like you might wanna lose those, they'll spend way too much time recovering.

i guess you could lower the current without losing much/any yield.. 46w may be a bit too much for such a small area(0.05m²?)

stagafolaysa, I've considered it, but I think I'll give them a few more days. They aren't very vigorous to begin with, probably due to them being crossed with parents from the original seeds from JLP. I'm growing in organic soil, a 5:3:2 mix of peat, perlite and worm castings with some dolomite lime. I used it last time and it was great.

Bueno, thanks! I think I am finally happy with it... :)

asde, I could lower the current but heat seems to be under control and my drivers don't allow for it, so 700mA it is for the time being. My grow area is about 2 cubic feet so you could say I'm maxing it out a bit! I can always turn one array off...

Sorry for the lack of updates everyone... life got a bit hectic for awhile! Unfortunately I'm traveling for a few weeks so I won't be able to update with pictures. I'll still be around to answer questions if they arise. In true nerd fashion I installed a USB camera to monitor my mini garden from my smartphone while I'm away.

After near death from overwatering, the plants have sprung back nicely. There's new growth everywhere and they are getting much bigger and skunkier. When they are getting the correct amount of water, they DO love the LED lamp and reach for it without stretching :)

The carbon scrubber works like a charm so far. I just ordered some good coconut carbon from a hydro supply company to test once the ladies start to flower. I really can't afford to have ANY smell whatsoever. Last time my home made scrubber was adequate until the last week or so... I'm hoping this design fares better.

Stay tuned...!

+Rep for the light instructions. Same amount of power I was looking for. I talked to Knna last year but funds ran out. Looks like blue and white ratio has been swapped. Is your lamp expected to veg and flower? My cab is something like 20"x18" and 2.5' tall. Would your lamp handle that well?

What size wire would you use? I have lots of that but would have to buy copper tape. Would kapton still be needed?

Thanks much

GP7, yes the USB camera works great. Now let's hope my blumat auto waterers work! So far so good and the plants look really happy.

Voidling, yes my lamp will veg and flower. The reds will handle the flowering but the plants now do love to lean toward the whites in veg. I would expect a light my size to work in your space. You could even go higher, as knna recommends maxing out lights in small spaces if you can. Then again you could start small and add on in the future depending on your needs. If you're new to DIY LED that's what I'd recommend. As for wire, any small, flexible size would work as we're not pushing massive current through it. I'd expect the size that PC molex connectors use would be about perfect. If you use wire for the traces between each LED you won't absolutely need kapton tape, but that plus the copper tape gives you an easy surface to solder to. You can get both very cheap at Dealextreme.

Thanks. All my soldering has been with wire so hopefully I'll be fine. Still waiting for my funds to buy the parts. In the meantime I just keep drooling over everyone else's setup

It's all good my friend :) Any soldering experience is good experience. Like I said I had none and managed to figure it out. But building your own will be worth the wait in the end.

awesome build mate,
your guide inspired me to possibly make my own LED :)

i never thought i would ever consider that.
gonna be subbing to this.

Hey 5j, thanks for stopping in! I hope to get results that justify my build and inspire others.

Here's my webcam view, and about 10 days of growth... the blumats are working great, so it seems, giving the perfect amount of water. It's nice to be able to check on my garden remotely.

Nice, I like that a lot. I need to project this into my cab wall to show my plants what they're supposed to be doing

The plants are doing quite well. The front plant is getting so big that it's blocking the others! The only thing I'm concerned with is the blumat water reservoir running out. For that I used a plastic container identical to the pots the pants are in, which holds about a gallon, sitting underneath. It should be enough for another week or two when I get back from my trip.

At any rate I'd consider using the blumats permanently since they water so well and the plants are happier than ever with extremely vigorous growth. I'm very impressed with them.

My soil mix is all organic: peat moss, perlite, dolomite lime and worm castings as the base, also I added bone/blood/kelp meal and azomite as extra goodies. The ability if the blumat juniors to keep the soil moist without overwatering probably encourages the microherd to thrive. Everytime I look the plants are bigger!

After a busy month abroad I'm finally back :wave:

I found the plants a bit dry and droopy when I returned due to the water level in the reservoir getting too low. (At least they survived!) I lost a few fan leaves because of this but we're back on track with two nice lemony females.

Once the soil is ready in a few days I'll be transplanting each lady to a one gallon pot and training them through a scrog screen, which I have yet to make.

I think I'll let them stretch their legs for a week or so before hitting the lights.

Then the fun begins! See you all soon.
