pc/ultimate scrog grow yield!

Hello peeps sweet thread please accept my apologies as I didnt finish reading your thread i made it to page 3 but I cant bare the suspense anymore as I am anxious to hear some feed back from you guys on my diy contraption I have built...

we have I think a 2008 emachines desktop pc gutted but exterior kept to spec. I have a brinks digi timer for 100w brinks MH light, 12v psu for fans and 5v psu for arduino which controls fan speed thru a couple n channel mosfets with pwm. and soon to add a few temp sensors and have the fans/heating element to automatically control temps to keep avg temp of 70-80F but as of now im winging it without even a water heater temps are low as room stays around 55-70 degrees depending on this southern winter weather but it is warmer in pc due to mh light except at night but not too much thanks to my idea to insert this glass it basically eliminated all heat issues its like two seperate rooms the glass is almost safe for plant to touch. I have just swapped from egg carton to homemade net basket with cut up cardboard egg carton medium now dwc till i decide if ebb/flow can fit/ is worth the trouble. but without futher ado i give you my reworked pc grow box 2013-01-29 02.10.07.jpg2013-01-29 02.09.53.jpg2013-01-29 02.07.33.jpg2013-01-29 02.07.12.jpg2013-01-28 22.27.08-1.jpg2013-01-28 22.27.08.jpg2013-01-29 02.11.16.jpg2013-01-29 02.10.34.jpg2013-01-29 02.15.08.jpg2013-01-29 02.14.46.jpg2013-01-29 02.14.26.jpgok I know it cant be considered stealth do to light output but i havent sealed it up yet or attached the ac filters to outlets but (hopefully)"she" is now about 1 to 1 and a half weeks and on 18/6 just now transferred to dwc and she had her first shot of nutes misted on leaves and medium and is no longer in milk jug humidity chamber I had to break down and use mg soil plant food cuz i had some and saw some browning tips and spots hopefully it will hold her off till I can order legit stuff but what you guys thinks of my hard work maybe she will pay off also im using bag seed till i can order some 90 day wonder or something sativa :) also any recommendations? preference on dwc vs eeb and flow/ flood and drain on 45 secs on/ 45 off or 24 hr mister/ sprinkler head. great work fellow grow boxers sometimes smaller can be better ;) im very optimistic now thx.... You can see my first video with my attempt at cloning, with mixture of willow water solution i made and a rooting powder, cuttings from my last late started grow half indo / outdo one actually turned completely purple at flowering it was beautiful http://www.youtube.com/watch?v=GyLaIi2C1ss

wow i stopped using this thread i thought noone looked at it already.
i am still doing a new pc grow but havent started a thread because i dont want to let you guys down again.
no untill i find out if its a female is when ill start a thread again.

was up with the 100w brinks mh light is it ment for growing?
how are the temps with that light.
and is the socket any diffrent then cfls meaning is the socket bigger?

you got a good looking grow looks kinda cramped in their
the glass does help but they told me it also takes light density off. so you might want to figure out a diffrent way without the glass?
im really intrested in ;your bulb since im going to cancel my cabinet grow 250w. do to money.
im making a mini fridge grow using cfls but if that brink bulb might do better is it like and mh/hps or diffrent?

Nice PC grows guys. I remember doing one for my first grow, ahh good times.

And this was 5g, LOL. But I had a ton of fun and I still use the case for cloning/starting seedlings.

Just caught up on this thread, but it was over 3 years ago when it started.
All the entries were dealing with CFL or HID lighting... I did this a LONG time
ago with CFL just as a proof of concept based on the old OverGrow site forums.

Am starting up again with the same PC chassis I used before, but taking out the
old lights and experimenting with some CXA1507s. They have a much smaller
footprint than the previous CFLs and will allow a bit more canopy room.

That concept grow was fine but not enough light, the buds were very fluffy.
Would have had a grow thread back then, but OverGrow got shut down about
2 weeks into my project, but that's ancient Drug War history...

So much new tech since then.
