I'm gonna plant 4 seeds. If all of them will be female, I'm gonna have 4 plants. And I'm gonna use metal halide for lighting. But I'll put them to the balcony to prevent the heat and smell problem, and also my balcony takes sunlight about 8 hours a day. I want to take advantage of sunlight. So the lamp will be open after the sunlight(total 18 hours [at the flowering process, I'll close the windows brackets and change the 6500K mh lamp with 2700k mh lamp]). Also I'll support the lower parts with 2 bulbs attached to the floor.

So the question is; how many watts will be enough for metal halide lamp, and each of the bulbs on the floor?

This'll be my first grow and what I learned from the topics here is these values changes from seed to seed. It's impossible to buy seeds here. I'm gonna plant the seeds that i found under my desk. They're all afghan and they had fallen down there so they should come from good stuffs :smile:
