I used a 1000 watt HPS for vegetive and a 1000 watt Metal
Halide for flowering in an 8x8 room usually fitting around
6-7 plants. I don't know if the lighting i used had anything to
do with the reflection off the flat white paint, most of the time
yielding around a pound- 2 pounds a plant give or take. (cured weight)
Maybe im just hard headed when i find something that works
I stick with it. The whole if its not broke don't fix it theory. Some
growers get to complicated in their growing methods and take
all the fun out of it. Growing is meant to be enjoyed. My advice
to any new grower indoor or out door is to buy a simple grow
book Ed Rosenthal's books are the ones i enjoyed the most
simple and to the point, and that if you are a beginner do
not expect some miraculous yield your first time around.
You will pick up little tricks of the trade with each grow and
over all make it an enjoyable experience not a stressful one.
Trying to fit all you have herd into your first go around will
only leave you in disappointment and possibly so feed up
that you give up on another try.

Ok im over my little speach proccess now.......LOL
Happy growing to all
