Masterkush Masterstealth CFL growbox

This will be my second and yet first real attempt. My last i started out with no clue but at end i knew whats what yet the only remaining plant was a male. Now i have built a new growbox 21x17x27 inches (l,w,h) out of a perfect old sewing machine box. It fits perfectly under my desk, has a lock and looks unsuspicious. After removing all sewing machine parts i painted the inside white, made two holes in back for fans and made a light fixture out of an ikea cd rack i had laying around. Currently there are 6 CFLs (4 cool and 2 warm) yet there is a remaining socket for a 7th. Total its about 125 Watts. In back i attached some air pipes (whatever the name really is) to vent the outgoing air away from the ingoing. Thermostat can be read form outside and in middle it is 80 F. All in all im very happy with how it turned out.
I have germinated 3 feminised masterkush seeds on September 4th, one germinated on the 6th, next on 7th and those two are now in soil, still waiting on third.
Here are some before/after pictures of the growbox

Might be interesting to post some building pics, took 2 days and had to build quietly because im in somewhat of a dorm. Try chisseling 2 holes with hardly any use of a hammer.

This is after removing all the sewing machine stuff...




Lights are from Ikea but wired 7 together so that there are only 3 plugs






This is generally what was done, all the little details left out oc (installing fans, sealing off etc..) There is a 10 F difference inside from top and bottom, ill try to even it out by placing a small fan inside mixing up all air.

have you given any thought to what strain you want to grow considering height restrictions. also if your in a college dorm be careful. i had a female friend who got a scholarship to a good college and lost it all due to smoking in her dorm room. hope your grow goes well and keep us posted.

Im growing feminised masterkush, will have to give it some training. And this isnt really a dorm but more like an appartement building just for students.

yeah i was wondering after i responded like "wait, its in the title and even his name is masterkoosh, doesnt he already know?"
Thanks for the interest anyways :-P.
Two seeds have germinated, potted and sprout yesterday. Ive have 3 of the 6 CFLs on atm to reduce the heat since the sprouts are way up by the lights and itll get over 90 if i turn on all at once. On bottom its under 80 so ill be getting a new fan to mix all the air around some time soon.
The third seed didnt germinate, i put it into soil to see if it does anything and started germinating seed number 4, this time making sure its in a warm place (aka on my laptop) thinking that might have been the problem. If all 4 grow instead of 3 i dont know what ill do seeing that the grow space would be too small.

No huge changes, the two sprouted plants are still growing, the old and newly (seed #3 and #4) germinating seeds are yet to sprout, i doubt the old one still will but the new one shoult pop out of the soul any time now.
I got myself a 125 Watt warm envirolight today, the temps would be around 93 if i added it now but im going to get a 230 volt fan from ebay within a week (if i "win" it tomorrow) that will be put into the growbox to circulate the air from the bottom and top, this way it will stay under 90F right under the bulbs.
After exchanging a warm 23 watt cfl for a cool ill have pretty much 125 watt cool in small cfls and 125 watt warm with the enviro. I purposly got the warm to ensure i have max light for flowering stage.
One mistake, i toppled over one of the plants, however it seems to be alright. From now on ill be more carefull.

The new bulb:

Hey Valuable, I am in almost the same situation as you with regards to being in uni accomodation and needing stealth, so im glad i found your thread =) awesome setup by the way, you have exactly what I am aiming for. I was thinking of PC growing but the price and size just dont seem worth it.
i was thinking of using my chest of drawers as a box (take out the drawers) and hanging enviro's inside. and use the front of the drawers to make it look normal.
one thing, what about the smell? when your MK starts flowering, it sure is guna stinnk hehe

Good job, Very nice setup & Very stealthy. I agree with danny about the smell, it's definitely something you'll need to address at some piont in your grow. Good luck and again good job

I have never heardof a successfull PC grow, the space is just too small. I was going to rebuild some drawers too but then i found this lockable cabinet and am glad i did. The smell is an issue ill deal with when i know how bad its getting but have thought about it oc. The smallest filter with fan would cost 100$ but a guy at the headshop advised me towards other things like oil that are supposed to work. I would also be interested in building my own filter but like i said, thatll come in a few weeks.

My 3rd and 4th seed dont want to germinate. The 3rd i can forget but i dont know why the new seed wont grow. Its prett frustrating, ill have to try to maximise the 2 plants i have, at least i know theyll be female.

Still wondering if i should LST or top them. And also if i should build a whole new smaller box to keep a plant for cloing in and use this box i have now to flower.

Progress report. Both are doing fine, ive either got bad seeds or im just not a good germinator (im afraid its the second). The last two seeds wont show any signs of life, cant imagine what im doing wrong.
The other two are doing well, happy as could be. Heres the pics

How in the world are you going to fit 4 MK or even 2 in that thing?
looks like itll be two, and thats something thatll have to work out with the right training.
I will be giving them new pots, i just need to find some that are wide rather than tall first. If im, they are, lucky then tomorrow.

I put in the 125 watt warm light, its mounted to the door and when its closed it lights them from the side. This is more of a simple fast way i could mount it instead of screwing it to the top but works rather well. When in flowering ill rearange the lights so the warms are above.
Now the two have 250 watts of CFLs.

Today i have ordered another 85W warm and 125W cool enviros.
Im planning on building a PC grow box for clones where ill be adding the new 125W light. The 85W will be added to the current grow box so i will have 330W and will be my flowering space.
I will need new pots asap but first i need to get some studying done.
