how small of a light

[bluntmaster9]

how small of a light can i use *specificly* and still get good results with 4-6 plants all CLOSE together - in a 3x3x4 chamber lined with foil. i need the smallest available light usage and size. *what for vegging and what for flowering?

I'd go with a 400W HPS, but you could probably go with a 250W..... but if you want good results, go with a 400W. you can veg under that as well.

this would be my first indo grow - i have no clue about lighting. is that an expensive light? and can you show me a link to some where online i can check one out?
thanks orecal!

 

[bluntmaster9]

cfl lights? or hps

 

[bluntmaster9]

never mind sorry - read up a post and realized

 

[ORECAL]

yeah, sorry........ i got distracted........I don't even remember what mine cost, I think about 500 bucks for 2 400W HPS ballasts and reflecters,

I got a 150w floralux from htgsupply that I use for my flowering, n i use 2 23w cfls in a different spot for my veg. I was gonna use cfls for flowering too, but when I saw how many more lumens I could get from a 150w hps than a 150w cfl, I had to get it....why don't you check out the cfl forum?

i haev a 400 hps in a space like that heat is a bitch make sure oyu vent.


also -- dont use foil.....

 

[bluntmaster9]

no foil? - how come. just curiouse - i have never grown indoors and from my 'research' using foil helps get the lights to the bottom of the plant. t hat is why i was going to try it. - i will try it w/o

 

[ORECAL]

foil creates hot spots.... concentrates the light in certain areas. it will burn your leaves.

use flat white paint, or mylar.......

and it gets fckd up real easy too, like orecal says, flat white paint or mylar

 

[bluntmaster9]

flat white paint sounds good. i will try it out.
thanks guys for all the help

 

[ORECAL]

no problem..... I'm just glad you didn't cook your plants.....

by using mylar you are reflecting 90% of the light being shown on it where as foil only reflects about 45% and as ORECAL said it creates hot spots
