thank you all for your advice.....i will set the lights at two feet from the top of the ladies and every 3 days i will make sure the woman goes to bathroom to wash her hair from my cum.......hahahaha the idea really makes me laugh but is safer than a plastic hanging bag full of water.....oh, sorry baby i missed your face......guys it's hard to achieve but i'll give it all to her hair if that is going to buy me enough time.......for ventilation these is a window.....with sills closed well enough so as to allow air circulation without any visible lights from outside....been outside and nothing can be seen.....more or less the air of the room changes...as we talk the window is a little bit open.....temp with the bulb on is constant at 25 celsius/77 farenhait.....when i am in the room it rises 2 degrees at 27/80.....i suppose this is optimal......during at night and with the window always open like now it drops at 18/64......again i think this is normal.....i will take care and this as well.....more or less i am 3 weeks from flowering.....hehehehe
