ok, so i feel its time for an update. my loving weasel slayed my crown bitch by ripping up the roots a few weeks ago. i'm bitter.

but not really so i started something new to help out with the continued cfl grows.

i used some seeds from good mids and germinated 9 of them. then i put a natural spec. 23w cfl about 2 - 2 1/2 feet above them. i figured that the strains that were more sensitive to light would look better and be the prime candidates. i got 4 of them to come up through the dirt, but one wasnt tough so now i'm at 3. i'll take pics within the next couple days to let u guys see what my setup looks like. now that i have my 3 winners i doubled the wattage and now have them 1 1/2" from the plants with a ghetto tech patented air cooled aluminum reflector over it.

so here is the unfinished pics of my rubbermaid box, i desided to use a piece of glass to create a wind tunnel for these tiny heaters. i have an indirect breeze from the bottom to exchange air, its at an even 75 degrees. i have some more work to do on the reflectors, i'll post pics of the babies when they come all the way up.



right above the big middle light is the outtake fan, 12v 3.5inch fan
where the glass starts on top there in an intake fan, same as above
on the bottom under the cups there is a smaller but same power fan


i need to windex that.

the cups are up on a little box . there is more room in there than the picture shows. i took out the glass too. had to lower the plants a little tho to get it back to 75. 95 watts of flourescent.

back to my design.......

MSince I had everything except the bulbs laying around the house My set up only cost me $40.00 LOL
me too.

that looks really good would u link me to the grow u did with that? or the one you're doing?

or just post it in the Post all CFL grows here link

here's the new pics after i did some adjustments. i made the ducts with project paper and everything adhesive here is 100% masking tape. every time i make something ghetto like this i pick a roll of tape and only use it. no mixing of tapes here folks. this is the real deal son.







welcome to the surface.. now grow my minions!

Emergency Blankets:

These are ultra thin polyester blankets that are sold in most camping stores and are constructed of a single layer of polyester film that is covered with a layer of vapor deposited aluminum.

It is not very effective at reflecting light because it is so thin. Holding it between you and a light source, many small holes are noticed at the intersections of creases and the entire blanket is translucent to begin with, this coupled with the many creases that are in it when you purchase it takes away a significant amount of it reflectivity. It is very easily creased as well which also detracts from its ability to reflect light. And while it is reflects nearly 90% of radiant heat energy, it is only able to reflect around 70% of the light.

The largest advantage of using this type of material is that it is very cheap and therefore easily replaced. Emergency blankets can create hotspots if not attached flush to the wall so it is important that no air gaps exist between it and your supporting wall. The easiest way to attach this is to use tape (Aluminum or metal tape is recommended), as it tears very easily once it is cut or punctured.


Aluminum Foil:
Aluminum foil is no more than 55% reflective - if used, make sure that the dull side is the one that is used to reflect the light. When it becomes creased its reflectivity is even lower (around 35%.) It is also very dangerous to use because it creates hotspots easily, is electrically conductive, and is a fire hazard when it is in close contact with HID lighting. Attaching this to walls is a pain and usually using aluminum tape or glue is the best way. This should only be used as a last resort, and even then its usefulness is questionable.

And now for the real fun. I use this and it totally ROCKS!

After all of that this is the cheapest and easist solution:


Flat white paint:

Self explanatory; a great option for large grow rooms or for people who are interested in a low maintenance wall. Flat white paint has the ability to reflect between 75-85% of the light, and does not create hotspots. Adding a fungicide is recommended when painting.

Glossy and eggshell whites not reflect light as efficiently as flat white. Semi-gloss paint for example, only has the ability to reflect between 55-60% of the light. Also important to remember when using paint is that any smears or blemishes on the surface take away from how reflective the wall is so care should be taken to avoid marking or staining the walls. Titanium white paint is very reflective; however it is usually only used on reflectors due to its high cost.

u know i was trying to avoid painting the inside of this little box, i'd rather hand sheets of flat white plastic or somethig just to avoid taking it out side and letting it dry. but--- if i can get a small spray can of this titanium white for like $5 i might do it. (u dont need to sell me on the flat white idea, ive always used it before and recommend it as well)

Somebody reccommended the cheap Mylar wrapping paper that they sell, after all it is not the thickness of the mylar but the reflectivity. so the mylar wrapping paper should work well . But I am usually wron about everything , ask my x wife.

It works very well. Just re-enforce the corners or anywhere you adhere it to the wall with tape. Remember that it works best when it is stretched pretty tight and without too many ripples and waves. Dust it off very gently once a week with a dry cloth to maintain the absolute brightness of the material.
