I know... I wasn't going to let the obvious newb tell you how great they are.

lol 500w would be an easy bake oven. At work when people leave the halogen desk-lamps leaning on the monitors it melts the monitor casing easily. I cant see a use for one at all in grow environment unless your growing with cfl and just need some heat

I use 4 flourescents two warm and two cool Whites, I usually keep them within inches until they are about three weeks old and then i'll go 8 inches and let them take off I have been growing for a while and have NO problems doing my grow this way. use drip feed but this time around i did EBB and Flow for Vegg.
When i flower them i usually take a couple clones off each one and let the clones become mothers (I have already established mine are all female) once the clones root i'll put my big girls into flower with a 400 watt HPS 12/12 and I use Ebb and Flow.

Hi everybody. thanks for your input.

I'm already building my dream..........................................

I've started with the idea in the drawings ..and I've got another thing... because of the space (read "height")... because of my belief.. fluoros will win.



Strange:

Every person that I see trying FLO and then it writes here that is using 2 maybe 3 maybe 4 maybe 5 FLO ..........and then sees that bud is late and switches to HPS.

Guys........ get real!

In my final solution (for now) I am using seventeen 21W HE tubes for an area of 2x3 feet with custom built reflector for each tube.

For now I don't have an Hps to mesure but what I can tell you is that I am beating MH big time

I am using this light meter:


.........so..... an 400 MH @ tolerable distance, at least one foot, is giving me a reading of +/- 40.000 LUX.

In my box I am reaching that with nine tubes... 21W each that is.

Pics & details will follow.

this was the first ideea

AND THIS IS WHAT I AM BUILDING NOW.

ur idea looks really cool and all. justthe top...
will it be ajustible? cause with floro's they can be like 2in away..

wont they stretch?

No is not adjustable. But the reflector shape that you see behind every tube is designed specially to focus the light in a beam.
Actually the plants are gonna receive more light when are small because they will be in the middle of the box where all the reflectors aim.


First I've created 4 reflector shapes:



after I decided for the second I've made a vector image for a friend of mine who cuts Styrofoam with a computer aided machine:




Another shape for holding the clams (hope this is the word):




And after gluing this I run out of pictures:

Looks like a good idea Keep up the good work

that does look cool. Keep us posted. As to cfls/fluorescents...I've pulled 2 ounces of dense high quality herb from a single 3' plant using a mix of warm cfls and a cool fluorescent 2 tube fixture.

hmm, your idea is looking wicked man, and even if you could really aim the light im pretty sure the plant can sence the light really isnt that close..
imm keep watching just too see cause i am curious as too making it work.
im deffinatly not saying you cant do it..

the only issue i see is that all the lights won't be getting to the plant until it is about fully mature. With cfls hanging from extension cords...you can adjust individual light sources daily if need be so that the are within a few inches of bud sites.

okay, i didnt want to start a new thread and i didnt know where to post so im just posting my question here.

i have ONE plant, its white widow btw, and im using a incandescent right now w/ 60 watt.

for the flowering stage however, i believe i need a light thats better but its just ONE plant not for a whole room, like a cupboard.


its a very small space and the plant could get too close to the light and get burned so it cant get very hot.
also price is a HUGE thing, its gotta be kinda cheap.

so what kind of light can i use that will work well? will a full spectrum fluorescent work? where can i find one?

thanks guys, hope you can help!

can you tel me how many WATS that was?

I work with the meter in few pics above so I kind of know what the plant are "sensing".
For now I have only 9 tubes running in the box and this are the numbers:

a. touching the tube with the meter 40.000lux
b. one inch away 28.000lux
c. four inches away 32.000lux
d eight inches to middle of the box 34.000lux

this is real data (little bit stupid that i don't have a camera, especially if you see all the other things i have around)

incandescent? 60?




an helpful answer will follow.

Each tube was 40 watts so that = 80 watts. Eight 23 watt warm cfls = 184 watts

So a grand total of 264 watts.

Ok. do you have pics from that?

I smell a non-believer.

My pleasure...

Add 23 more watts to my total...apparently i used 9 cfls not 8. It's the constant adjustment of the individual cfls...keeping them with 2" of bud sites and blanketing the plant with light that made a difference.

That thread has a in-closet shot 37 days into flower. (so that you can see just how close i got the lights)

No way ) I'm a believer.

I've started a post asking you about positioning & distance of the light, vent, reflective material or withe ...................then I've realized that better ask for photos and if not then I ask the questions
