seriously guys, theres so much info on this board, i could become a guru without anybody knowing. Seems like every question I have can be answered either by searching or in the FAQ. But I just have to post and get your guys' two cents on some things.

What might be some ideal demenions for a container for 2 to three plants (of snow white in particular)?

And, do you guys think one computer fan would be sufficient ventilation? or should I go for two or three?

Also, I've decided as far as lighting goes I can get two 125w cfl's for vegging and probably graduate to 400 hps or perhaps a 1000 hps (considering im going to up the ante a bit when i move so i can accomadate more plants). I duno, what do you guys think/recommend?

I'm definately anxious to get my seeds and start growing. I also cant wait to start a journal(seeing that its the cool thing to do ;))

That's all for now!

sounds like a good idea but i would add at lest one or two more fans it can get hot under the lights even cfls.

i might add 2 or 3 more cfl too.


Approximate light production:
Incandescents: 17 lumens/watt
Mercury vapor: 45-50 lumens/watt
Fluorescents: 60-70 lumens/watt
Metal halide: 90 lumens/watt
High pressure sodium: 107 lumens/watt


Determine the square footage of your area (example in a 4 foot by 4 foot area, there is 16 square feet)
If you have a 1000 watt High Pressure Sodium, that produces (approx.) 107,000 lumens.
Divide this by 16 (your square footage) 107,000 / 16 = 6687 lumens per square foot.
So just divide the total amount of Lumens, by the total amount of Sq ft, and thats your lumens per square foot.


The minimum amount of light required by marijuana plants is around 3000 lumens per square foot. However, it's not 100% accurate, since although you may have a 10,000 lumen light, the amount of light that reaches the plant varies with the distance between the light and plants, and reflectivity of the grow box. The ideal amount is somewhere around 7000-10,000 lumens/sqft, and as long as the plants do not burn, as much light can be used as you want.
(*note, the sun produces about 10,000 lumens/sqft, on a sunny summer day).
