I know a guy who was going to trash some old PCs and I told him I'd take them for parts. I just got one of those flip video cameras so I decided to produce a series of videos showing how I built my PC grow box. I'll be uploading them on my YouTube channel as soon as I have all the footage edited and annotated.
For now I thought I should upload some photos and get some feedback on my build. Although I did put a lot of time and thought into this I ended up making a really simple mistake. I forgot to wire the timer inside the box. I kind of ran out of space anyway but now I"m stuck with the problem of the fans going off with the lights... No air circulation at night could cause mold or bacteria to form which is no good! (I might have a solution) Plus the entire point of my PC build was to be stealth and I don't know anyone else who has their computer plugged into a timer. Anyway here are some of the first pics I'm uploading for the world to see! This will be my third grow but first PC micro grow. Im excited ... sorry if you hate these smilies, I like using them.
...as you can see I have a little more work to do on the door. The computer case was originally one piece. I used a dremel to cut the panel off. I have a light trap built around two fans for the exhaust and two fans mounted to the front of the PC drawing in cool air. There is also one fan inside the case circulating air and drawing the heat away from the lights. Each is wired separately and has its own switch. To be more specific I wired two fans together for both the exhaust and intake so even though there is a total of 5 fans (probably overkill) there are only three switches. I decided to use this many fans because Im also using 5 CFL's which Im sure some of you will say is overkill... but I say the more light the better!! Still devising a plan for some kind of custom carbon filter. I'll add it when smell becomes a problem.
Having this many lights will also allow me to cover more of the light spectrum. Right now I have it set up to veg with (4) 23W 5000K @ 1500 lumens each and (1) 75W 6500K @ 1170 lumens. I know you're supposed to use 6500K lights to veg but my 5000K CFL's push out more lumens...maybe one of you advanced growers can tell me what I should do about that. I plan on keeping it mostly 6500K to 5000K for veg but I'm thinking about swapping out one of the 5000K for a 2700K...what do you growers think?
You might also be wondering why I choose to wire the fans the way I did... reason being I'm thinking about using CO2 and I would like to be able to regulate the temp and airflow as much as possible. I've been researching the amount of CO2 thats supposed to be in the air in order to be useful and so far a lot of people are saying in the neighborhood of 1000 - 1200 ppm. Im wondering if thats true and whats the best way to use CO2 in a micro grow like this? Please let me know if you have any information about it, preferable from personal experience...
I also attached a picture of the seeds Im germinating as of 4/13/2011. I have 5 different bag seeds, one of which is immature but I'm hoping it sprouts because the bud was a great medication. I have them in a small tupperware container between two layers of moist/wet napkin...light proofed the clear lid with a few layers of magazine and tape. Now the container is sitting inside my entertainment system on top of my cable box where it stays nice and warm from the heat of venting electronics.
I don't know what I'm going to do if they all sprout; I'm only going to attempt to grow one or two in the PC grow box at a time. I have a feeling I'm going to want to let them grow bigger so I've started drawing a plan for a small stealth closet grow which this may or may not turn into. I'll at least keep one plant in the PC start to finish for the sake of this thread. I plan on doing an LST grow or maybe some super cropping who knows. I'd like to try training it into a spiral to utilize as much horizontal grow space as possible and maximize my yield.
