Oh good, so much useful information. I think i'll leave the lights on during the night so the temperature doesn't fall too low, and than use the lights during the day for filming. Also i'll go with the 18/6 method. Oh also the electricity is cheaper at night so extra bonus. Also there is a small window in the room that also gives out some light that i'll cover up with something.
I would also like to ask a few more questions. How high does the plant usually grow and also how much distance should there be between the plant and the lights? Also also XD, how big pots do you recommend i seed them in? And what fertelizer do you recommend? I was thinking of using horse manure or is that a mistake?
As for the lights i was thinking something in the line of the bellow links. Just the stands. What light bulbs do you recommend besides HPS? Also anyone knows the wattage?
Also thank you so much, every tip is helpful
