I looked around, what are my options. I find a big store what selling CFL bulbs. I find some bulb what I think I can be use.
23W 1380L 6500K CFL bulb. I figured if I use 6 bulb like this I got 8280L from 138W. You say its better than 1 big bulb, but I dont really understand why.
The 125W CFL bulb what I see first can make 10000L. Why is it better if I use more smaller one? (Perhaps because of the light coming from different directions) I cant find another option. Because at first glance the one big bulb have better properties (125W, 10000L , 6X23W=8280L). Do not want to be clever, I accept the advice, just do not understand why is it better...
In my country I find a grown forum (simply plants, not AF) and in the site I find a grown calculator. It sad for my box (40cmX50cmX80cm) need about 7000L. It can be enought? If its workable I will go to the shop in this week and by the bulbs.
